-How to Apply These Terms to Your New Programs
-
-If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
-
-To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.
-
-<one line to give the program's name and a brief idea of what it does.>

-
-You should have received a copy of the GNU General Public License along with this program. If not, see <https://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode:
-
-<program> Copyright (C) <year> <name of author>
-This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box".
-
-You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see <https://www.gnu.org/licenses/>.
-
-The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read <https://www.gnu.org/ licenses/why-not-lgpl.html>.

-### Requirements for the SC
+## Publishing
 
-* Study processes which can be generalized are abstracted and modeled in that manner that the structure can be adapted to any german university.
-* It must be platform- and software-independent.
-* Search interface must be clearly specified that different working groups with different search tools can retrieve the same search results.
-* Must be expandable.
-
-### Generate documentation for routes
-
-To generate a documentation for the routes use the following command.
+After having added all changes using `pnpm changeset`
 
 ```shell
-node --require ts-node/register src/cli.ts routes PATH/TO/ROUTES.md
+pnpm publish-packages
 ```
 
-### Annotations
+Internally, this will run
 
-Annotations are used to add additional informations to fields, which are used to autogenerate mappings from the core objects. 
-External dependencies can not be covered by the annotations. Documentation about some of the annotations can be found in: [typedoc](https://typedoc.org/guides/doccomments/)
+```shell
+pnpm changeset version # bump versions
+pnpm syncpack:fix
+pnpm format:fix # changes to the package.json can cause issues
+pnpm install # update lockfile and rebuild packages
+git add .
+git commit -m "refactor: update changelog"
+pnpm changeset tags
+git push --follow-tags
+# from here the pipeline will do the publishing
+```

+## Remote caching
 
-*Note: tags ignore casing, but for consistency they should use the variants proposed here.*
+Turbo supports remote caching, which massively speeds up build processes.
+
+### Connecting to the remote cache locally
+
+`.env.local`
+
+```dotenv
+TURBO_API=http://example:3000
+TURBO_TEAM=openstapps
+TURBO_TOKEN=abc123
+```
+
+### Connecting to the remote cache in GitLab Pipelines
+
+You will need to define
+
+- `TURBO_API`
+- `TURBO_TEAM`
+- `TURBO_TOKEN`
+  Like you did locally as described in [this](https://turbo.build/repo/docs/ci/gitlabci#remote-caching)
+  guide.
+
+### Hosting a cache
+
+Self-hosting via Docker is extremely simple, just follow
+[this](http://v2202207178592194230.supersrv.de:6341) guide
+or in short:
+
+`.env`
+
+```dotenv
+PORT=...
+TURBO_TOKEN=...
+```
+
+```shell
+docker run --env-file=.env -p 3000:3000 fox1t/turborepo-remote-cache
+```
+
+## Useful commands
+
+#### Why is this package bloating the app?
+
+```shell
+pnpm why --prod -r --filter @openstapps/app PACKAGE
+```
+
+#### Licenses
+
+```shell
+pnpm licenses --prod --filter PROJECT
+```

+### Major Changes
+
+- 64caebaf: Migrate config system to cosmiconfig
+
+  Configs are now written using type-checked JavaScript
+
+  ```js
+  // @ts-check
+
+  // This file is now type-safe just like TypeScript, but
+  // without the compilation step
+
+  /** @type {import('@openstapps/package').Type} */
+  const foo = {};
+  ```
+
+  You can write config files in JavaScript, JSON, or other
+  cosmiconfig-supported formats.
+
+  The config files now are
+
+  - `backendrc.{js,json,...}`
+  - `elasticsearchrc.{js,json,...}`
+  - `prometheusrc.{js,json,...}`
+
+  You can also split them into multiple files,
+  as well as using the `markdown.js` helper in
+  `config/default/tools` to include markdown files
+  as text (see `config/f-u/about-pages`)
+
+- 64caebaf: Move project to a turbo monorepo & pnpm
+
+  Internal dependencies are now defined using `"@openstapps/package": "workspace:*"`
+
+  - Removed extraneous files from packages
+    - `.npmrc`
+    - `.npmignore`
+    - `.mailmap`
+    - `.gitignore`
+    - `CONTRIBUTING.md`
+    - `LICENSE` (Project license file is added upon publishing, see [pnpm.io](https://pnpm.io/cli/publish))
+    - `package-lock.json`
+    - `.editorconfig`
+    - `.eslintrc.json` (moved eslint config to `package.json`)
+    - `.eslintignore`
+    - `.gitlab-ci.yml` (Most workflows are workspace-level)
+    - `.gitlab/**` (issue templates etc. are now workspace-level)
+    - `.dockerignore` (Docker files are determined by which files are deployed with `pnpm deploy`, as per `package.json/files`)
+  - TSConfig has been moved to its own package (You can now use `"extends": "@openstapps/tsconfig"`)
+  - Removed ESLint and Prettier peer dependency hell by injecting them through the `.pnpmfile.cjs`
+  - Added syncpack for keeping dependency versions in sync (and consistent key ordering in `package.json`)
+  - Replaced conventional changelog with changesets
+  - Apps with binaries now use a top level `app.js`
+
+  ```js
+  #!/usr/bin/env node
+  import './lib/app.js';
+  ```
+
+- 64caebaf: Migrate to ESM
+
+  CommonJS is no longer supported in any capacity. To use the new
+  version, you will need to migrate your package to ESM.
+  We recommend using `tsup` and `Node 18`.
+
+  ```json
+  {
+    "type": "module"
+  }
+  ```
+
+- 64caebaf: Migrate package to Node 18
+
+  - Consumers of this package will need to migrate to Node 18 or
+    higher.
+  - Packages have been migrated from promisified `readFile` or
+    `readFileSync` towards `fs/promises`
+  - Packages use native `flatMap` now
+
+- 0a7e6af1: Migrate es mapping types from es-mapping-generator to .d.ts next to generated mappings
+- 64caebaf: Migrate build system to `tsup`
+
+  All packages now use an `index.ts` file to expose contents.
+
+  You will need to migrate paths from `import foo from '@scope/package/lib/foo` to `import foo from '@scope/package'`
+
+### Minor Changes
+
+- 64caebaf: Migrate integration tests from docker-compose solution to a shell script
+
+  `api-cli` no longer builds as a Docker container as a result.
+
+- 64caebaf: Migrate tests to C8/Chai/Mocha
+
+  - `@testdeck` OOP testing has been removed.
+  - Tests have been unified
+  - CommonJS module mocking has been replaced through
+    refactoring of tests, as ES Modules cannot be mocked
+    (do yourself a favor and don't try to mock them)
+  - C8 now replaces NYC as a native coverage tool
+
+- 64caebaf: Migrate away from `@krlwlfrt/async-pool`
+
+  ```ts
+  import {mapAsyncLimit} from '@openstapps/collection-utils';
+
+  await mapAsyncLimit(
+    [1, 2, 3],
+    async it => {
+      await someNetworkRequest(it);
+    },
+    5,
+  );
+  ```
+
+### Patch Changes
+
+- 64caebaf: Migrated changelogs to changeset format
+
+  ```js
+  import fs from 'fs';
+
+  const path = 'packages/logger/CHANGELOG.md';
+
+  fs.writeFileSync(path, fs.readFileSync(path, 'utf8').replace(/^#+\s+\[/gm, '## ['));

+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+Preamble
+
+The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+The precise terms and conditions for copying, distribution and
+modification follow.
+
+TERMS AND CONDITIONS
+
+0. Definitions.
+
+"This License" refers to version 3 of the GNU Affero General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+1. Source Code.
+
+The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+The Corresponding Source for a work in source code form is that
+same work.
+
+2. Basic Permissions.
+
+All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+8. Termination.
+
+You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+13. Remote Network Interaction; Use with the GNU General Public License.
+
+Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.

+# backend (a reference implementation of a StApps backend)
+
+This project is a reference implementation for a StApps backend. It provides an HTTP API to index data into a database,
+perform full text search, sorts and filters. It also delivers the configuration needed by the app. The API is specified
+within the [@openstapps/core](https://gitlab.com/openstapps/core).
+
+If you want to perform requests, index data or search within JavaScript or TypeScript you should consider using our client
+[@openstapps/api](https://gitlab.com/openstapps/api).
+
+Or generate your own client using the openapi/swagger definitions you can get form the [API documentation](https://openstapps.gitlab.io/backend).
+
+# Usage
+
+This backend is not a standalone software. It needs a database like Elasticsearch to work.
+
+If you just want to use the backend you should consider using
+[minimal-deployment](https://gitlab.com/openstapps/minimal-deployment). The minimal-deployment will provide
+you with everything you need to run this backend.
+
+# Local usage for development purposes
+
+## Requirements
+
+- Elasticsearch (8.4)
+  - [ICU analysis plugin](https://www.elastic.co/guide/en/elasticsearch/plugins/current/analysis-icu.html)
+  - OR Docker
+- Node.js (~14) / NPM
+
+### Startup Behaviour
+
+_This might be important if you work on the Core_
+
+The backend is using Elasticsearch Mappings and Aggregations from its currently used `core` dependency.
+
+## Start Database (Elasticsearch)
+
+Elasticsearch needs some configuration and plugins to be able to work
+with the backend. To save you some work we provide a
+[docker image](https://gitlab.com/openstapps/database) which
+only needs to be executed to work with the backend.
+
+Run `docker run -d -p 9200:9200 registry.gitlab.com/openstapps/database:latest`
+
+Elasticsearch should be running at port 9200 now. If you have problems with
+getting elasticsearch to work, have a look in the
+[README](https://gitlab.com/openstapps/database) of the image
+first.
+
+## Metrics collection
+
+The backend contains an express middleware which can be optionally enabled by setting the environment variable
+`PROMETHEUS_MIDDLEWARE` to `true`. The middleware collects metrics and provides a [Prometheus](https://prometheus.io/)
+compatible endpoint from which the metrics may be scraped by Prometheus.
+
+The middleware may be configured with JSON provided in `config/prometheus.json`, i.e.
+
+```JSON
+{
+  "metricsPath": "/metrics",
+  "collectDefaultMetrics": true,
+  "requestDurationBuckets": [0.1, 0.5, 1, 2, 5, 10, 20],
+  "requestLengthBuckets": [512, 1024, 5120, 10240, 51200, 102400],
+  "responseLengthBuckets": [512, 1024, 5120, 10240, 51200, 102400]
+}
+```
+
+The available options are documented on [npmjs](https://www.npmjs.com/package/express-prometheus-middleware) or the [homepage](https://github.com/joao-fontenele/express-prometheus-middleware#readme) of the express-prometheus-middleware project. You may get a compatible grafana dashboard at [grafana.com](https://grafana.com/grafana/dashboards/14565).
+
+## Start backend
+
+Run `npm install` and `npm run build`, then start with `npm start`. The server should now be accepting connections at `http://localhost:3000`.
+
+# Environment Variables
+
+To select a database implementation you have to set the `NODE_CONFIG_ENV` variable. At the time only `NODE_CONFIG_ENV=elasticsearch` is supported.
+Set `NODE_ENV=production` to run backend for production usages. In production the backend expects some kind of monitoring to be set via the
+environment. At the time only SMTP is being implemented. The backend wouldn't start if you don't provide SMTP authentification. Alternatively
+you can set `ALLOW_NO_TRANSPORT=true`. To set up an SMTP configuration have a look at
+[@openstapps/logger](https://gitlab.com/openstapps/logger).
+
+The list of environment variables includes:
+
+- `NODE_ENV` when set to `production`, there will be a reduced amount of output from the logger
+- `PORT` when this is not set, the backend will default to port 3000
+- `ES_ADDR` the Elasticsearch address, if not set it will default the Elasticsearch address to `http://localhost:9200`
+- `ALLOW_NO_TRANSPORT` if set to true, the backend will allow starting without an Email configured that receives critical errors.
+- `ES_DEBUG` setting this to `true` will result in Elasticsearch logging to be **VERY** extensive, in almost all situation this should no be enabled.
+- `PROMETHEUS_MIDDLEWARE` if set to `true` will enable metrics collection with [Express Prometheus Middleware](https://www.npmjs.com/package/express-prometheus-middleware)
+
+## Config files
+
+Each university can have it's specific config for the general backend and app and for all databases.
+
+All config files can be found in `./config/`. There is a `default.ts` which is used by default. You can create an
+university specific file with following naming scheme: `default-<university license plate>.ts`
+
+A university specific file will only overwrite all properties of the `default.ts` that are set in the file itself.
+To start the backend using your configuration you have to provide the `NODE_APP_INSTANCE` environment variable
+with your university license plate.
+
+To set a database you have to provide the `NODE_CONFIG_ENV` environment variable with the name of the database.
+At the time only Elasticsearch is implemented.
+
+To create your university specific config file for the elasticsearch you have to create a file with following naming
+scheme: `elasticsearch-<university license plate>.ts`.
+
+## Debugging
+
+Set `ES_DEBUG=true` to enable verbose Elasticsearch tracing information.
+This can be useful to debug some issues between backend and elasticsearch.

+
+Die App verlinkt an einigen Stellen auf die Website der Goethe-Universität sowie auf andere, externe Websites, die in einem In-App-Browser dargestellt werden. Wir bitten Sie bei Aufruf dieser Websites, die dort geltenden gesonderte Datenschutzhinweise und Erklärungen zu beachten.
+
+### <u>2. Zweck(e) der Datenverarbeitung</u>
+
+**Zugriff auf Standortdaten**
+
+Für die Navigation benötigt die Goethe-Uni-App Zugriff auf den Standort des verwendeten Endgerätes (Location Based Services). Bei einer Anfrage erhebt die App den aktuellen Standort über GPS, Funkzellendaten und WLAN-Datenbanken, um Ihnen als Nutzer:in Informationen zu Ihrer unmittelbaren Umgebung geben zu können. Der Zugriff auf die Standortdaten erfolgt nur, wenn Sie den Zugriff auf die Standortdaten erlauben. Daten zu Ihrem Standort werden ausschließlich für die Bearbeitung von standortbezogenen Anfragen genutzt und um Ihren Standort auf der Karte anzuzeigen.
+
+**Zugriff auf Zugriffsdaten**
+
+Die Speicherung und Verarbeitung von Protokolldateien erfolgt, um die Funktionsfähigkeit der Goethe Uni-App für Sie sicherzustellen. Zudem benötigen wir die die Daten aus Gründen der Sicherheit unserer informationstechnischen Systeme. Eine anderweitige Auswertung oder Weitergabe findet in diesem Zusammenhang nicht statt.
+
+**Zugriff auf Spracheinstellungen**
+
+Der Zugriff auf die Spracheinstellung erfolgt um Ihnen die Oberfläche der App in der von Ihnen gewünschten Sprache anzuzeigen.
+
+**Zugriff auf die Einstellung der Statusgruppe**
+
+Der Zugriff auf die Einstellung der Statusgruppe erfolgt um Ihnen in der App die für Ihre Gruppe zutreffenden Informationen anzuzeigen, z.B. Mensapreise

+
+Die Verarbeitung der personenbezogenen Daten aus der Feedbackfunktion dient uns zur Kontaktaufnahme und Fehlerbehebung.
+
+**Zugriff auf personenbezogene Daten bei der Kalendersynchronisation**
+
+Der Zugriff auf die Termindaten erfolgt um sie bei aktivierter Kalenderfunktion in den Gerätekalender zu schreiben.
+
+**Zugriff auf Daten der Campus Dienste**
+
+Der Zugriff auf das Campus Management Systems erfolgt ausschließlich um persönliche Daten der Studierendenverwaltung in der App anzuzeigen (z.B. Prüfungsnoten).
+
+**Zugriff auf bibliotheksspezifische personenbezogene Daten**
+
+Der Zugriff auf die Daten (z.B. Ausweisnummer, Name, Postanschrift) erfolgt zur Durchführung von Bestell- und Ausleihverfahren von Büchern und sonstigen Materialien der Universitätsbibliothek. Die vollständigen Angaben zu den Verarbeitungszwecken finden Sie in der Datenschutzerklärung der Bibliothek: https://www.ub.uni-frankfurt.de/benutzung/datenschutz.html
+
+### <u>3. Rechtsgrundlage(n) für die Datenverarbeitung</u>
+
+Die Nutzung der Nutzungs-/Zugriffsdaten („Protokolldateien") basiert auf Artikel 6 Absatz 1 lit. f) DSGVO.
+
+Für alle spezifischen Funktionen, bei denen die Datenverarbeitung auf Ihrer freiwilligen Einwilligung als Nutzer:innen basiert, werden explizit Einwilligungen bzw. aktive Zustimmungsakte („Opt-In") eingeholt. Die Bereitstellung personenbezogener Daten zu Ihrer Person gegenüber der Goethe-Universität erfolgen dabei auf freiwilliger Basis. Die Rechtsgrundlage ist in diesen Fällen jeweils Artikel 6 Absatz 1 lit. a) DSGVO. Sie können Ihre jeweilige Einwilligung jederzeit einzeln widerrufen bzw. Ihre Einstellungen ändern.
+
+### <u>4. Datenlöschung und Speicherdauer</u>
+
+Die in den Protokolldateien der App erfassten Daten werden sieben Tage nach dem Ende des Zugriffs automatisch gelöscht oder anonymisiert.
+
+Die Löschfristen bzw. Speicherdauer der in den Bibliotheksystemen erfassten Daten finden Sie in der Datenschutzerklärung der Bibliothek: https://www.ub.uni-frankfurt.de/benutzung/datenschutz.html
+
+Für alle anderen Funktionen und Dienste gilt: Die Löschung erfolgt hier je nach Vorgabe des genutzten Dienstes. Die personenbezogenen Daten der betroffenen Person werden gelöscht oder gesperrt, sobald der Zweck der Speicherung entfällt.
+
+### <u>5. Datenweitergabe/Datenübermittlung</u>
+
+Ihre personenbezogenen Daten werden von uns nicht an Dritte weitergegeben.
+
+Von Betreiberseite wird durch technische und organisatorische Maßnahmen sichergestellt, dass Dritte keinen Zugriff auf die verarbeiteten Daten, wie z. B. Nutzungsdaten, erhalten. Ein Auftragsverarbeitungsverhältnis nach Art. 28 DSGVO besteht nicht, da ausschließlich eigene Server verwendet werden.
+
+### <u>6. Automatisierte Entscheidungsfindung</u>

+## Information on the processing of personal data
+
+### <u>1. Scope of the processing of personal data</u>.
+
+According to Article 4 DSGVO, personal data is any information relating to an identified or identifiable natural person.
+
+We process personal data of you as a user inside of the Goethe University App to the extent that this is technically necessary for the provision of a **functional application**.
+
+Furthermore, data processing may be based on your voluntary consent if you wish to use **specific functions**.
+
+We therefore distinguish below between
+
+- Access data when using the app: content of requests, IP addresses, date/time of request, requested URL, error codes, browser identifier, HTTP header.
+
+- Location and navigation: voluntary location information
+
+- User settings: voluntary specification of a) language preferences (currently: German/English), b) status (e.g. guest/student) or c) specific search queries and search results (notifications)
+
+- Calendar function: voluntary use of the calendar function (optional with voluntary use of a sync function: opt-in) or the integrated timetable function. The following data is processed and stored on the users device: appointments and events
+
+- Feedback function and contacting: voluntary use with the provision of contact data and, if applicable, voluntary transmission of log data
+
+- Campus services: voluntary use with processing of grade view, matriculation number, email address, name
+
+- Services of the library: voluntary use with processing of library account data, such as ID number with name, e-mail address, postal address, right of use, order data, fees, reservation, loan data. Full details of processing can be found in the library's privacy policy:<br />
+  https://www.ub.uni-frankfurt.de/benutzung/datenschutz.html
+
+In some places, the app links to the Goethe University website and to other external websites that are displayed in an in-app browser. When you visit these websites, we ask you to pay attention to the separate data protection notices and declarations that apply there.
+
+### <u>2. Purpose(s) of data processing</u>
+
+**Access to location data**.
+
+For navigation, the Goethe University app requires access to the location of the end device used (location-based services). When a request is made, the app collects the current location via GPS, radio cell data and WLAN databases in order to be able to give you as a user:in information about your immediate surroundings. The location data is only accessed if you allow access to the location data. Data about your location is only used to process location-related requests and to display your location on the map.
+
+**Access to access data**.
+
+Log files are stored and processed to ensure that the Goethe Uni app functions properly for you. In addition, we need the data for reasons of security of our information technology systems. No other evaluation or disclosure takes place in this context.
+
+**Access to language settings**.
+
+Access to the language setting is made in order to display the interface of the app in the language of your choice.
+
+**Access to the status group setting**.
+
+Access to the status group setting is provided to show you the information in the app that applies to your group, e.g. canteen prices.
+
+**Access to personal data when using the feedback function**.
+
+We use the processing of personal data from the feedback function to contact you and troubleshoot problems.
+
+**Access to personal data when synchronizing calendars**.
+
+Appointment data is accessed in order to write it to the device calendar when the calendar function is enabled.
+
+**Access to Campus Services data**.
+
+Access to the Campus Management System is solely for the purpose of displaying personal student management data in the app (e.g., exam grades).
+
+**Access to library-specific personal data**.
+
+Access to data (e.g., ID number, name, mailing address) is for the purpose of carrying out ordering and borrowing procedures for books and other materials from the University Library. Full details of the purposes of processing can be found in the Library's Privacy Policy: https://www.ub.uni-frankfurt.de/benutzung/datenschutz.html
+
+### <u>3. Rechtsgrundlage(n) für die Datenverarbeitung</u>
+
+The use of usage/access data ("log files") is based on Article 6(1)(f) DSGVO.
+
+For all specific functions where data processing is based on your voluntary consent as a user:in, explicit consent or active acts of consent ("opt-in") are obtained. The provision of personal data about you to Goethe University is done on a voluntary basis. The legal basis in each of these cases is Article 6 (1) a) DSGVO. You can individually revoke your respective consent or change your settings at any time.
+
+### <u>4. Data deletion and storage duration</u>
+
+The data collected in the log files of the app are automatically deleted or anonymized seven days after the end of the access.
+
+The deletion periods or storage duration of the data collected in the library systems can be found in the library's privacy policy: https://www.ub.uni-frankfurt.de/benutzung/datenschutz.html
+
+For all other functions and services, the following applies: deletion takes place here depending on the specifications of the service used. The personal data of the data subject will be deleted or blocked as soon as the purpose of the storage no longer applies.
+
+### <u>5. Data disclosure/data transfer</u>
+
+We will not pass on your personal data to third parties.
+
+On the part of the operator, technical and organizational measures are taken to ensure that third parties do not gain access to the processed data, such as usage data. An order processing relationship according to Art. 28 DSGVO does not exist, as only our own servers are used.
+
+### <u>6. Automated decision-making</u>
+
+Automated decision-making, including profiling, does not take place.
+
+## Rights of the data subject
+
+If personal data is processed by you, you are a data subject within the meaning of the GDPR. The assertion of your data subject rights is free of charge. You can, of course, contact us for this purpose. You are entitled to the following data subject rights vis-à-vis Goethe University:
+
+### <u>1. Right of access</u>
+
+You can request confirmation from us as the controller as to whether and which of your personal data is being processed by us. You have the right to request copies of your personal data from us. Please note the exceptions that may arise due to specific regulations.
+
+### <u>2. Right of rectification</u>
+
+You have the right to request us to rectify and/or complete, if the processed personal data concerning you is not (anymore) accurate or not (anymore) complete.
+
+### <u>3. Right to restriction of processing</u>
+
+Under certain conditions, you can request the restriction of the processing of personal data concerning you, i.e. that your personal data is then not deleted, but marked so that further processing is restricted.
+
+### <u>4. Right to erasure</u>
+
+Under certain conditions, you can demand that we delete the personal data concerning you without delay. This is particularly the case if the personal data is no longer necessary for the purpose for which it was originally collected or processed.
+
+### <u>5. Right to information</u>
+
+If you have asserted the right to rectification, erasure or restriction of processing against us, we are obliged to inform all recipients to whom the personal data concerning you have been disclosed of this rectification or erasure of the data or restriction of processing, unless this proves impossible or involves a disproportionate effort. You are entitled to be informed about these recipients.
+
+### <u>6. Right to data portability</u>
+
+Under certain conditions, you have the right to request that we transfer your personal data directly to another controller or organization. Alternatively, under certain conditions, you have the right to request that we ourselves provide you with the data in a machine-readable format.
+
+### <u>7. Right to object</u>
+
+If we process your personal data because the processing is in the public interest, part of our public duties, or if we process your data on the basis of a legitimate interest, you have the right to object at any time to the processing of data relating to you for reasons arising from your particular situation.
+
+### <u>8. Right to revoke the declaration of consent under data protection law</u>
+
+If we process your personal data because you have given us your consent, you have the right to revoke your declaration of consent at any time.
+
+### <u>9. Right to lodge a complaint with a supervisory authority</u>
+
+You also have the right to lodge a complaint with a supervisory authority. The competent supervisory authority will examine your complaint.
+
+## **Contact details of the supervisory authority in the area of data protection**

+# Goethe-Uni App 2.4
+
+Wir freuen uns euch mehr in der Goethe-Uni App
+bieten zu können.
+
+## Navigation zu Gebäuden und Orten
+
+Als eines der Ergebnisse des Ideenwettbewerbs wurde jetzt
+ein Navigationsfeature in die App integriert.
+
+Orte auf der Karte, Mensen, sowie sogar Termine (wenn hinterlegt)
+bieten jetzt direkt die Option eine Verbindung zu finden, gestützt
+durch die Karten App auf deinem Gerät.
+
+## Integration der Jobbörse
+
+Jobs findest du ab sofort auch in der Goethe-Uni App.
+
+Auch das ist ein Ergebnis des Ideenwettbewerbs,
+und wir freuen uns es euch hier präsentieren zu können!
+
+## Der Umweltscore
+
+Der Umweltscore für Gerichte wird nun auch in der App angezeigt.
+
+> Nachhaltigkeit, Umweltschutz, Gesundheit und Klimawandel sind
+> zentrale Begriffe im gesellschaftlichen Miteinander.
+> Unsere Ernährung spielt hierbei eine wichtige Rolle.
+> Das Studierendenwerk Frankfurt am Main zeichnet seine Speisenpläne
+> ab sofort mit einem Umweltscore aus.
+> Anhand dieser Bewertung können Sie direkt ersehen,
+> welchen Einfluss Ihre Essenauswahl auf das Klima hat.
+
+## Weitere Verbesserungen
+
+### Performance
+
+Die Performance der App beim Navigieren wurde stark verbessert und ist datensparender.
+
+### Kalender
+
+Die Kalenderabschnitte haben jetzt neue Namen bekommen:
+
+- Der _Kalender_ zeigt Termine für spezifische Tage
+- Die _Wochenübersicht_ ist ein Stundenplan mit allen Termine, die sich wiederholen (z. B. Vorlesungen)
+- Die _Einzeltermine_ zeigen alle Termine, die sich nicht wiederholen
+  (z. B. Klausuren)
+
+### Meine App
+
+Der "Meine Kurse" Abschnitt wurde überarbeitet, und zeigt jetzt Termine
+für die nächsten Tage und mit mehr Details an.

+
+## Navigation to buildings and places
+
+As part of the "Ideenwettbewerb," the idea competition,
+we have now integrated a navigation feature into the app.

+
+## Integration of the job market
+
+Jobs are now also available in the Goethe-Uni App.
+
+This feature is also a result of the idea competition,
+and we're happy to be able to present it to you here!
+
+## The environment score
+
+The environment score for dishes is now displayed inside the app.
+
+> Sustainability, environment protection, health, and climate change are
+> central topics in how we live today in our society.
+> Our eating habits play an important role in it.
+> The "Studierendenwerk Frankfurt am Main" is marking up its menus
+> from now on with the so-called "Umweltscore," the environment score.
+> Based on this rating, you can see the impact your meal choice would have on our climate.
+
+## Further improvements
+
+### Performance
+
+The performance while navigating around the app has been heavily improved and requires less data to work.
+
+### Calendar
+
+The calendar sections have new names:
+
+- The _calendar_ shows appointments on specific days
+- The _week overview_ is a schedule with all events that repeat (e.g. lectures)
+- The _single events_ show all appointments that don't repeat (e.g. exams)
+
+### My App
+
+The "my courses" section has been revamped,
+and now shows events for the next days and with more detail.
