+
+## Build Instructions
+
+### Prerequisites
+
+1. **Initialize submodules:**
+   ```bash
+   git submodule update --init --recursive
+   ```
+   This MUST be done first before any build attempts.
+
+2. **Set up environment variables:**
+   ```bash
+   export ANDROID_NDK_ROOT=/path/to/ndk/27.0.12077973
+   export PATH=${PATH}:${ANDROID_NDK_ROOT}/toolchains/llvm/prebuilt/linux-x86_64/bin/:${ANDROID_NDK_ROOT}
+   ```
+   Note: Path format varies by OS (linux-x86_64, darwin-x86_64, etc.)
+
+3. **Install Rust toolchains:**
+   ```bash
+   scripts/install-toolchains.sh
+   ```
+   Required for building the native Rust components.
+
+4. **Build native libraries:**
+   ```bash
+   scripts/ndk-make.sh
+   ```
+   **IMPORTANT:** First run takes 30-60 minutes as it builds for all architectures (armeabi-v7a, arm64-v8a, x86, x86_64).
+   For faster development builds, build for a single architecture:
+   ```bash
+   scripts/ndk-make.sh armeabi-v7a
+   ```
+
+5. **Build APK:**
+   ```bash
+   ./gradlew assembleDebug
+   ```
+   Build time: ~2-5 minutes after native libraries are built.
+
+### Build Flavors
+
+- **gplay:** Google Play version with Firebase Cloud Messaging (applicationId: `com.github.arcanechat`)
+- **foss:** F-Droid version without proprietary services (applicationId: `chat.delta.lite`)
+
+### Build Outputs
+
+- Debug APKs: `build/outputs/apk/gplay/debug/` and `build/outputs/apk/fat/debug/`
+- Release APKs require signing configuration in `~/.gradle/gradle.properties`
+
+### Common Build Issues
+
+1. **Missing NDK or incorrect version:**
+   - Error: `ANDROID_NDK_ROOT not set` or native library missing
+   - Solution: Install NDK 27.0.12077973 and set ANDROID_NDK_ROOT environment variable
+
+2. **Submodules not initialized:**
+   - Error: Missing deltachat-core-rust files
+   - Solution: Run `git submodule update --init --recursive`
+
+3. **Gradle wrapper validation:**
+   - Always validate gradle wrapper before building: `./gradlew wrapper --gradle-version=current`
+   - Wrapper is validated in CI via `gradle/actions/wrapper-validation@v4`
+
+4. **Clean build issues:**
+   - If build fails, try: `./gradlew clean && scripts/ndk-make.sh && ./gradlew assembleDebug`
+   - Remove `build/` directory if clean doesn't work
+
+## Testing
+
+### Running Unit Tests
+
+```bash
+./gradlew test
+```
+Expected duration: 1-3 minutes
+
+### Running Instrumented Tests
+
+1. **Disable animations** on your device/emulator:
+   - Developer Options → Set "Window animation scale", "Transition animation scale", and "Animator duration scale" to 0x
+   - **CRITICAL:** Tests will fail if animations are enabled
+
+2. **Run tests:**
+   ```bash
+   ./gradlew connectedAndroidTest
+   ```
+   Expected duration: 10-30 minutes depending on device/emulator
+
+### Online Tests
+
+Some tests require real email credentials. Configure in `~/.gradle/gradle.properties`:
+```properties
+TEST_ADDR=youraccount@yourdomain.org
+TEST_MAIL_PW=yourpassword
+```
+
+### UI Tests and Benchmarks
+
+- Located in `src/androidTest/java/com/b44t/messenger/`
+- Test categories: `uitests/online/`, `uitests/offline/`, `uibenchmarks/`
+- Run via Android Studio: Run → Edit Configurations → Android Instrumented Test
+
+## Coding Conventions
+
+### General Guidelines
+
+1. **Embrace existing style:** Match the coding style of the file you're editing
+2. **Minimize changes:** Don't refactor or rename in the same PR as bug fixes/features
+3. **Readable over paradigmatic:** Favor readability over strict Java patterns
+4. **Avoid premature optimization:** Keep things simple and on point
+5. **No excessive abstraction:** Avoid unnecessary factories, one-liner functions, or abstraction layers
+6. **Comments:** Only add comments if they match existing style or explain complex logic
+
+### Architecture
+
+- **UI/Model Separation:** Delta Chat Core (Rust) handles the model layer
+- **High-level interface:** Core provides data in UI-ready form; avoid additional transformations in UI layer
+- **Direct approach:** Prefer direct implementation over excessive class hierarchies
+
+### Key Principles
+
+- Work hard to avoid options and up-front choices
+- Avoid speaking about keys/encryption in primary UI
+- App must work offline and with poor network
+- Users don't read much text
+- Consistency matters
+- Primary UI should only show highly useful features
+
+## Common Development Tasks
+
+### Adding New Features
+
+1. Consider the UX philosophy (minimal options, offline-first, simplicity)
+2. Check if core library changes are needed before implementing in UI
+3. Match existing code style in modified files
+4. Add instrumented tests for UI changes when appropriate
+5. Update relevant documentation
+
+### Modifying Core Integration
+
+- Core library is in `jni/deltachat-core-rust/` submodule
+- Java bindings are in `src/main/java/com/b44t/messenger/Dc*.java`
+- JSON-RPC bindings in `chat.delta.rpc.*` package (generated via dcrpcgen)
+
+### Generating JSON-RPC Bindings
+
+To regenerate JSON-RPC bindings after core changes:
+```bash
+./scripts/generate-rpc-bindings.sh
+```
+**Note:** Requires Rust tooling and [dcrpcgen tool](https://github.com/chatmail/dcrpcgen) installed
+
+### Working with Translations
+
+- Translations managed via Transifex (not in repository)
+- English source strings: `res/values/strings.xml`
+- Don't mix string changes with refactoring
+
+### Debugging Native Code
+
+Decode crash symbols:
+```bash
+$ANDROID_NDK_ROOT/ndk-stack --sym obj/local/armeabi-v7a --dump crash.txt > decoded.txt
+```
+
+## Validation and Quality Checks
+
+### Pre-commit Checks
+
+Before committing changes, always run:
+
+1. **Gradle wrapper validation:**
+   ```bash
+   ./gradlew wrapper --gradle-version=current
+   ```
+
+2. **Build verification:**
+   ```bash
+   ./gradlew assembleDebug
+   ```
+
+3. **Unit tests:**
+   ```bash
+   ./gradlew test
+   ```
+
+4. **Code style:** Match existing code style in modified files (no automatic formatter configured)
+
+### When to Rebuild Native Libraries
+
+Rebuild native libraries (`scripts/ndk-make.sh`) when:
+- Updating deltachat-core-rust submodule
+- Modifying anything in `jni/` directory
+- Changing NDK version
+- After `git clean -fdx` or fresh clone
+
+**DO NOT** rebuild native libraries for:
+- Pure Java/Kotlin code changes
+- Resource file changes
+- Gradle configuration changes (unless changing native library linking)
+- Documentation updates
+
+## WebXDC Support
+
+ArcaneChat has extended WebXDC support:
+- `window.webxdc.arcanechat` - Version detection
+- `sendToChat()` - Extra properties: `subject`, `html`, `type` (sticker/image/audio/video/file)
+- External link support in apps
+- `manifest.toml` - `orientation` field for landscape mode
+
+## Important Files
+
+- `build.gradle` - Main build configuration (Android Gradle Plugin 8.11.1, Java 8 compatibility)
+- `CONTRIBUTING.md` - Contribution guidelines
+- `BUILDING.md` - Detailed build setup instructions
+- `RELEASE.md` - Release process
+- `proguard-rules.pro` - ProGuard configuration (enabled for both debug and release)
+- `google-services.json` - Firebase configuration (gplay flavor only)
+- `settings.gradle` - Gradle settings
+- `.github/workflows/` - CI/CD configuration
+
+## Dependencies and Constraints
+
+- **Java Version:** Java 8 compatibility (do not use Java 9+ features)
+- **Gradle:** Use wrapper (`./gradlew`) to ensure correct Gradle version
+- **NDK:** Must use version 27.0.12077973 (specified in build.gradle)
+- **Min SDK:** 21 (Android 5.0) - code must be compatible
+- **Target SDK:** 36 (Android 16) - test on this API level when possible
+- **ProGuard:** Always enabled - ensure ProGuard rules are correct for new dependencies
+- **Multi-dex:** Enabled - app exceeds 65k method limit
+
+## Package Structure
+
+- `org.thoughtcrime.securesms.*` - Main UI components (legacy namespace from Signal)
+- `com.b44t.messenger.*` - Delta Chat core integration
+- `chat.delta.rpc.*` - JSON-RPC bindings (generated)
+
+## Notes for AI Assistants
+
+- This is a fork of Delta Chat Android with ArcaneChat-specific improvements
+- Maintain compatibility with Delta Chat core library
+- Test on both gplay and foss flavors when making changes
+- Native library must be rebuilt after core changes
+- ProGuard is enabled in both debug and release builds
+- Multi-dex is enabled due to app size
+
+## CI/CD Workflows
+
+### Preview APK Workflow (.github/workflows/preview-apk.yml)
+
+Runs on every pull request to build and upload a preview APK:
+
+1. **Setup steps:**
+   - Checks out repository with submodules
+   - Validates Fastlane metadata
+   - Sets up Rust cache (working-directory: jni/deltachat-core-rust)
+   - Sets up Java 17 (Temurin distribution)
+   - Sets up Android SDK
+   - Caches Gradle dependencies
+   - Sets up NDK r27
+
+2. **Build process:**
+   ```bash
+   scripts/install-toolchains.sh && scripts/ndk-make.sh armeabi-v7a
+   ./gradlew --no-daemon -PABI_FILTER=armeabi-v7a assembleFossDebug
+   ```
+   Note: Builds only armeabi-v7a for faster CI builds
+
+3. **Output:** Uploads APK artifact to GitHub Actions
+
+### Important CI Considerations
+
+- Always validate Gradle wrapper before committing changes
+- Fastlane metadata must be valid (validated in CI)
+- Use `--no-daemon` flag for Gradle in CI environments
+- CI builds use FOSS flavor to avoid Google Services dependencies
+- Expected CI build time: 15-25 minutes for full workflow

+When checking out _deltachat-android_, make sure also to check out the
+subproject _deltachat-core-rust_:
+
+- When using Git, you can do this initially by
+  `$ git clone --recursive https://github.com/deltachat/deltachat-android`
+  or later by `git submodule update --init --recursive`. If you do this in your
+  home directory, this results in the folder `~/deltachat-android` which is just fine.
+
+## Generate JSON-RPC bindings
+
+To generate/update the JSON-RPC bindings (ex. `chat.delta.rpc.*` package)
+install Rust tooling (read sections below) and the [dcrpcgen tool](https://github.com/chatmail/dcrpcgen)
+then generate the code running the script:
+
+```
+./scripts/update-rpc-bindings.sh
+```
+
+## Build Using Nix
+
+The repository contains [Nix](https://nixos.org/) development environment
+described in `flake.nix` file.
+If you don't have Nix installed,
+the easiest way is to follow the [Lix installation instructions](https://lix.systems/install/)
+as this results in a setup with [Flakes](https://nixos.wiki/wiki/Flakes) feature enabled out of the box
+and can be cleanly uninstalled with `/nix/nix-installer uninstall` once you don't need it anymore.
+
+Once you have Nix with Flakes feature set up start the development environment shell:
+```
+nix develop
+```
+Nix development environment contains Rust with cross-compilation toolchains and Android SDK.
+
+To [build an APK](https://developer.android.com/studio/build/building-cmdline) run the following 2 steps.
+Note that the first step may take some time to build for all architectures. You can optionally read 
+[the first comment block in the `ndk-make.sh` script](https://github.com/deltachat/deltachat-android/blob/master/scripts/ndk-make.sh) 
+for pointers on how to build for a specific architecture.
+```
+$ scripts/ndk-make.sh
+$ ./gradlew assembleDebug
+```
+
+Resulting APK files can be found in
+`build/outputs/apk/gplay/debug/` and
+`build/outputs/apk/fat/debug/`.
+
+## Build Using Dockerfile
+
+Another way to build APK is to use provided `Dockerfile`
+with [Docker](https://www.docker.com/) or [Podman](https://podman.io/).
+Podman is a drop-in replacement for Docker that does not require root privileges.
+
+If you don't have Docker or Podman setup yet, read [how to setup Podman](#setup-podman)
+below. If you don't want to use Docker or Podman, read [how to manually install the
+build environment](#install-build-environment).
+
+First, build the image `deltachat-android` by running
+```
+podman build --build-arg UID=$(id -u) --build-arg GID=$(id -g) . -t deltachat-android
+```
+or
+```
+docker build --build-arg UID=$(id -u) --build-arg GID=$(id -g) . -t deltachat-android
+```
+
+Then, run the image:
+```
+podman run --userns=keep-id -it --name deltachat -v $(pwd):/home/app:z -w /home/app localhost/deltachat-android
+```
+or
+```
+docker run -it --name deltachat -v $(pwd):/home/app:z -w /home/app localhost/deltachat-android
+```
+
+You can leave the container with Ctrl+D or by typing `exit` and re-enter it with 
+`docker start -ia deltachat` or `podman start -ia deltachat`.
+
+Within the container, install toolchains and build the native library:
+```
+deltachat@6012dcb974fe:/home/app$ scripts/install-toolchains.sh
+deltachat@6012dcb974fe:/home/app$ scripts/ndk-make.sh
+```
+
+Then, [build an APK](https://developer.android.com/studio/build/building-cmdline):
+```
+deltachat@6012dcb974fe:/home/app$ ./gradlew assembleDebug
+```
+
+### Troubleshooting
+
+- Executing `./gradlew assembleDebug` inside the container fails with `The SDK directory '/home/user/Android/Sdk' does not exist.`:
+
+  The problem is that Android Studio (outside the container) automatically creates a file `local.properties` with a content like `sdk.dir=/home/username/Android/Sdk`,
+  so, Gradle-inside-the-container looks for the Sdk at `/home/username/Android/Sdk`, where it can't find it.
+  You could:
+  - either: remove the file or just the line starting with `sdk.dir`
+  - or: run `./gradlew assembleDebug` from outside the container (however, there may be incompatibility issues if different versions are installed inside and outside the container)
+
+- Running the image fails with `ERRO[0000] The storage 'driver' option must be set in /etc/containers/storage.conf, guarantee proper operation.`:
+
+  In /etc/containers/storage.conf, replace the line: `driver = ""` with: `driver = "overlay"`.
+  You can also set the `driver` option to something else, you just need to set it to _something_.
+  [Read about possible options here](https://github.com/containers/storage/blob/master/docs/containers-storage.conf.5.md#storage-table).
+
+## <a name="setup-podman"></a>Setup Podman
+
+These instructions were only tested on a Manjaro machine so far. If anything doesn't work, please open an issue.
+
+First, [Install Podman](https://podman.io/getting-started/installation).
+
+Then, if you want to run Podman without root, run:
+```
+sudo touch /etc/subgid
+sudo touch /etc/subuid
+sudo usermod --add-subuids 165536-231072 --add-subgids 165536-231072 yourusername
+```
+(replace `yourusername` with your username).
+See https://wiki.archlinux.org/index.php/Podman#Rootless_Podman for more information.
+
+## <a name="install-build-environment"></a>Install Build Environment (without Docker or Podman)
+
+To setup build environment manually:
+- _Either_, in Android Studio, go to "Tools / SDK Manager / SDK Tools", enable "Show Package Details",
+  select "CMake" and the desired NDK (install the same NDK version as the [Dockerfile](https://github.com/deltachat/deltachat-android/blob/master/Dockerfile)), hit "Apply".
+- _Or_ read [Dockerfile](https://github.com/deltachat/deltachat-android/blob/master/Dockerfile) and mimic what it does.
+
+Then, in both cases, install Rust using [rustup](https://rustup.rs/)
+and Rust toolchains for cross-compilation by executing `scripts/install-toolchains.sh`.
+
+Then, configure `ANDROID_NDK_ROOT` environment variable to point to the Android NDK
+installation directory e.g. by adding this to your `.bashrc`:
+
+```bash
+export ANDROID_NDK_ROOT=${HOME}/Android/Sdk/ndk/[version] # (or wherever your NDK is) Note that there is no `/` at the end!
+export PATH=${PATH}:${ANDROID_NDK_ROOT}/toolchains/llvm/prebuilt/linux-x86_64/bin/:${ANDROID_NDK_ROOT}
+```
+
+After that, call `scripts/ndk-make.sh` in the root directory to build core-rust.
+Afterwards run the project in Android Studio. The project requires API 25.
+
+With chance, that's it :) - if not, read on how to set up a proper development
+environment.
+
+
+## Install Development Environment
+
+1. Some libs required by Android Studio may be missing on 64 bit Linux machines
+   [Source](https://developer.android.com/studio/install.html)], so for Ubuntu execute
+   `$ sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 libbz2-1.0:i386`
+   and for Fedora execute
+   `$ sudo yum install zlib.i686 ncurses-libs.i686 bzip2-libs.i686`.
+
+2. Download Android Studio from <https://developer.android.com> (android-studio-ide-...-linux.zip)
+   and unpack the archive which contains a single folder called `android-studio`;
+   move this folder e.g. to `~/android-studio`.
+
+3. To launch Android Studio for the first time, open a terminal, navigate to
+   `~/android-studio/bin`, execute `./studio.sh` and use all the standard values
+   from the wizard.
+
+4. Android Studio now asks you if you want to open an existing project;
+   choose `~/deltachat-android` as created in the "Build" chapter (Android Studio starts to
+   build the project, however, there are some steps missing before this will
+   succeed).
+
+5. If components are missing, click on the corresponding error
+   message and install eg. required SDKs and the "Build-Tools" (you should
+   also find the option at "Tools / Android / SDK Manager / SDK Platforms").
+   Now the build should succeed - but the app still misses the native part.
+
+6. Download Android NDK from
+   [NDK Archives](https://developer.android.com/ndk/downloads)
+   and extract the archive containing a single folder
+   called something like `android-ndk-r23b-linux`; move this folder e.g. to `~/android-ndk`.
+
+7. Export the folder path to your environment as `ANDROID_NDK_ROOT` and add it to `PATH`.
+   You can achieve this e.g. by adding this to your `.bashrc`
+   ```bash
+   export ANDROID_NDK_ROOT=${HOME}/android-ndk
+   export PATH=${PATH}:${ANDROID_NDK_ROOT}/toolchains/llvm/prebuilt/linux-x86_64/bin/:${ANDROID_NDK_ROOT}
+   ```
+
+## Run UI Tests and Benchmarks
+
+- You don't necessarily need a dedicated testing device.
+  Backup your current account first, maybe there are some bugs in switching accounts.
+
+- You can run benchmarks on either an emulated device or a real device.
+  You need at least Android 9. For better benchmark results,
+  you should run the benchmark on a real device and make sure that the core is compiled in release mode.
+
+- Disable animations on your device, otherwise the test may fail:
+  at "Developer options"
+  set all of "Window animation scale", "Transition animation scale" and "Animator duration scale" to 0x
+
+- In Android Studio: "File" / "Sync project with gradle files"
+
+- In Android Studio: "Run" / "Edit configurations" / "+" / "Android Instrumented test":
+  Either select a specific class or select "All in Module" / "OK" /
+  Select your configuration in the toolbar / Click on the green "run" button in the toolbar to run the tests
+
+### Get the benchmark results
+
+When the benchmark is done, you will get a result like
+`MEASURED RESULTS (Benchmark) - Going thorough all 10 chats: 11635,11207,11363,11352,11279,11183,11137,11145,11032,11057`.
+You can paste `11635,11207,11363,11352,11279,11183,11137,11145,11032,11057`
+into a cell in a LibreOffice spreadsheet, do "Data" / "Text to columns",
+choose `,` as a separator, hit "OK", and create a diagram.
+
+### Run online tests
+
+For some tests, you need to provide the credentials to an actual email account.
+You have 2 ways to do this:
+
+1. (Recommended): Put them into the file ~/.gradle/gradle.properties (create it if it doesn't exist):
+   ```
+   TEST_ADDR=youraccount@yourdomain.org
+   TEST_MAIL_PW=youpassword
+   ```
+
+2. Or set them via environment variables.
+
+## Decoding Symbols in Crash Reports
+
+```
+$ANDROID_NDK_ROOT/ndk-stack --sym obj/local/armeabi-v7a --dump crash.txt > decoded.txt
+```
+
+`obj/local/armeabi-v7a` is the extracted path from `deltachat-gplay-release-X.X.X.apk-symbols.zip` file from https://download.delta.chat/android/symbols/
+
+Replace `armeabi-v7a` by the correct architecture the logs come from (can be guessed by trial and error)
+
+### Deobfuscating Java/Kotlin Stack Traces
+
+Because the app uses code minification (ProGuard/R8), Java stack traces in crash reports are obfuscated.
+To decode them, use `retrace` with the `mapping.txt` file that is included in the symbols zip:
+
+```
+retrace mapping.txt crash.txt > decoded-crash.txt
+```
+
+`mapping.txt` is extracted from the same `deltachat-gplay-release-X.X.X.apk-symbols.zip` file available at https://download.delta.chat/android/symbols/

-and may follow different coding styles and conventions.
-
-If you do a PR fixing a bug or adding a feature,
-please embrace the coding convention you see in the corresponding files,
-so that the result fits well together.
-
-Do not refactor or rename things in the same PR
-to make the diff small and the PR easy to review.
-
 Project language is Java.
 
+Code formatting is enforced via [Spotless](https://github.com/diffplug/spotless) Gradle plugin.
+Auto-format all files by running `./gradlew spotlessApply` before opening a PR.
+CI will fail if files are not formatted correctly so make sure to run the formatter before pushing.
+
+If you do a PR fixing a bug or adding a feature, do not refactor or rename things in the same PR
+to make the diff small and the PR easy to review.

 By using [Delta Chat Core](https://github.com/deltachat/deltachat-core-rust)
 there is already a strong separation between "UI" and "Model".
 Further separations and abstraction layers are often not helpful

-## Detailed data protection information
-
-### 1. Name and contact information of the data controller
-
-Responsible for the processing of your personal data is 
-```
-    Asiel Diaz Benitez
-    Reichsgrafen Str. 20
-    79102 Freiburg
-    Germany
-```
-E-mail: [adbenitez@duck.com](mailto:adbenitez@duck.com)
-
-### 2. Processing when using the ArcaneChat e-mail messenger
-
-All data is stored locally on your device or with your e-mail provider. Neither we nor ArcaneChat developers have any possibility to access the end user's data, as all communication and data processing takes place on the end user's device without ArcaneChat servers being involved. Only for the optional Push Notification (see 2.2) the Push Notification Token is processed by Delta Chat servers without them having any knowledge about the messages themselves, not even in encrypted form.
-
-#### 2.1 Sign up with your e-mail provider
-
-ArcaneChat communication works through your e-mail account. In order to establish the connection, the app needs the access data. These are only stored locally on your end device:
-
-- e-mail address
-- your password
-
-The legal basis for the processing is [Art.6 (1) lit.b GDPR](https://gdpr-info.eu/art-6-gdpr/), as you have a usage contract with us by using our services. 
-
-Security procedures are in place to protect the confidentiality of the data:
-Only the bare data needed to fulfil the user request of login are stored,
-encryption takes place as well as local sandboxing,
-see 2.3 for further details.
-
-#### 2.2 Heartbeat push notification
-
-Push notifications can be sent to the user's phone at regular intervals to enable receipt of messages while the ArcaneChat app is not currently active. Current messages can then be retrieved on the end device. The token is only created if the user wants reliable receipt of messages even when the app is not active. 
-
-In order to use push notifications, a unique identifier or token (Push Notification Token) is created after the app is downloaded and installed. This token allows Delta Chat servers to send notifications to the user's device. The token is generated and provided by the provider. The token is then stored on our systems and sent to the device at regular intervals to cause the app to retrieve new messages from the e-mail provider. Our systems have no knowledge of whether a message arrives or who may have sent a message.
-
-The aforementioned data will only be processed with your consent, in accordance with [Art.6 (1) lit.a GDPR](https://gdpr-info.eu/art-6-gdpr/).
-
-#### 2.3 Data in the app
-
-The ArcaneChat app works in a data-saving way. All relevant data is stored exclusively on the respective end devices:
-
-```
-- chat histories (text messages, voice messages, media, ...).
-- contacts
-- settings 
-```
-ArcaneChat servers have no access to this data, not even in encrypted form, as data processing takes place only on the end devices.
-
-#### 2.4 App permissions
-
-Within the app, you can enter, manage, and edit various information, tasks, and activities. The app also requires the following permissions:
-
-<table>
-    <thead>
-        <tr>
-            <th>Permission</th>
-            <th>Reason</th>
-        </tr>
-    </thead>
-    <tbody>
-        <tr>
-            <td>Internet access</td>
-            <td>This is needed to send the messages to the communication partner. </td>
-        </tr>
-        <tr>
-            <td>Camera access</td>
-            <td>
-This is needed for you to take photos and send them via the app. In addition, the camera access allows you to scan QR codes.
-            </td>
-        </tr>
-        <tr>
-            <td>Microphone access (optional)</td>
-            <td>
-This permission allows you to send voice messages.
-            </td>
-        </tr>
-        <tr>
-            <td>Location access (optional)</td>
-            <td>
-This is needed if you want to share your location with a communication partner.
-            </td>
-        </tr>
-        <tr>
-            <td>Background location access (optional)</td>
-            <td>
-This will be needed if you want to share your location over a certain period of time.
-            </td>
-        </tr>
-        <tr>
-            <td>Contact access (optional)</td>
-            <td>
-This allows you to load and save contacts from your phone book into the app. The contact data is stored locally in the app and not forwarded and stored on ArcaneChat server.
-            </td>
-        </tr>
-        <tr>
-            <td>
-Storage (optional)
-            </td>
-            <td>You can save images and files from the app to your device.</td>
-        </tr>
-    </tbody>
-</table>
-
-The processing and use of the above permissions are performed to provide the service. The internet access is necessary for the use, therefore the legal basis of the processing is [Art.6 (1) lit.a GDPR](https://gdpr-info.eu/art-6-gdpr/), as you have a usage contract with us by using our services.
-
-The optional permissions only take place based on your consent according to [Art.6 (1) lit.a GDPR](https://gdpr-info.eu/art-6-gdpr/) and can also be reduced to individual services, e.g. only internet usage to send messages without pictures or location data. ArcaneChat does not receive any access to this data.
-
-### 3. Platform dependent processing
-
-Certain information is already processed automatically as soon as you use the app. We have listed below which personal data is processed exactly:
-
-When you download the app, certain required information is transmitted to the app store you use ( e.g. Google Play or Apple App Store), in particular the username, the email address, the customer number of your account, the time of the download, payment information as well as the individual device identification number may be processed. The processing of this data is carried out exclusively by the respective app store and is beyond our control.
-
-For the rest, we refer to the data protection policies of the respective app store providers or responsible parties of the operating systems. We do not collect and/or process any other data.
-
-Your personal data will not be transferred to third parties for purposes other than those listed below.
-
-# 4. Rights of the data subject
-
-As a data subject of a processing of personal data, you have the right to 
-
-1. request information about your personal data processed by us in accordance with [Art.15 GDPR](https://gdpr-info.eu/art-15-gdpr/). In particular, you can request information about the processing purposes, the category of personal data, the categories of recipients to whom your data have been or will be disclosed, the planned storage period, the existence of a right to rectification, erasure, restriction of processing or objection, the existence of a right of complaint, the origin of your data if it has not been collected by us, as well as the existence of automated decision-making including profiling and, if applicable, meaningful information about its details;
-2. in accordance with [Art.16 GDPR](https://gdpr-info.eu/art-16-gdpr/) of the GDPR, immediately request the correction of inaccurate or incomplete personal data stored by us;
