+
+## 🔄 Auto-Sync Implementation
+
+### WorkManager Periodic Task
+
+Auto-sync is based on **WorkManager** with the following configuration:
+
+```kotlin
+val constraints = Constraints.Builder()
+    .setRequiredNetworkType(NetworkType.UNMETERED)  // WiFi only
+    .build()
+
+val syncRequest = PeriodicWorkRequestBuilder<SyncWorker>(
+    30, TimeUnit.MINUTES,  // Every 30 minutes
+    10, TimeUnit.MINUTES   // Flex interval
+)
+    .setConstraints(constraints)
+    .build()
+```
+
+**Why WorkManager?**
+- ✅ Runs even when app is closed
+- ✅ Automatic restart after device reboot
+- ✅ Battery-efficient (Android managed)
+- ✅ Guaranteed execution when constraints are met
+
+### Network Detection
+
+Instead of SSID-based detection (Android 13+ privacy issues), we use **Gateway IP Comparison**:
+
+```kotlin
+fun isInHomeNetwork(): Boolean {
+    val gatewayIP = getGatewayIP()         // e.g. 192.168.0.1
+    val serverIP = extractIPFromUrl(serverUrl)  // e.g. 192.168.0.188
+    
+    return isSameNetwork(gatewayIP, serverIP)  // Checks /24 network
+}
+```
+
+**Advantages:**
+- ✅ No location permissions needed
+- ✅ Works with all Android versions
+- ✅ Reliable and fast
+
+### Sync Flow
+
+```
+1. WorkManager wakes up (every 30 min)
+   ↓
+2. Check: WiFi connected?
+   ↓
+3. Check: Same network as server?
+   ↓
+4. Load local notes
+   ↓
+5. Upload new/changed notes → Server
+   ↓
+6. Download remote notes ← Server
+   ↓
+7. Merge & resolve conflicts
+   ↓
+8. Update local storage
+   ↓
+9. Show notification (if changes)
+```

+
+## <20> Sync Trigger Overview
+
+The app uses **4 different sync triggers** with different use cases:
+
+| Trigger | File | Function | When? | Pre-Check? |
+|---------|------|----------|-------|------------|
+| **1. Manual Sync** | `MainActivity.kt` | `triggerManualSync()` | User clicks sync button in menu | ✅ Yes |
+| **2. Auto-Sync (onResume)** | `MainActivity.kt` | `triggerAutoSync()` | App opened/resumed | ✅ Yes |
+| **3. Background Sync (Periodic)** | `SyncWorker.kt` | `doWork()` | Every 15/30/60 minutes (configurable) | ✅ Yes |
+| **4. WiFi-Connect Sync** | `NetworkMonitor.kt` → `SyncWorker.kt` | `triggerWifiConnectSync()` | WiFi enabled/SSID changed | ✅ Yes |
+
+### Server Reachability Check (Pre-Check)
+
+**All 4 sync triggers** use a **pre-check** before the actual sync:
+
+```kotlin
+// WebDavSyncService.kt - isServerReachable()
+suspend fun isServerReachable(): Boolean = withContext(Dispatchers.IO) {
+    return@withContext try {
+        Socket().use { socket ->
+            socket.connect(InetSocketAddress(host, port), 2000)  // 2s Timeout
+        }
+        true
+    } catch (e: Exception) {
+        Logger.d(TAG, "Server not reachable: ${e.message}")
+        false
+    }
+}
+```
+
+**Why Socket Check instead of HTTP Request?**
+- ⚡ **Faster:** Socket connect is instant, HTTP request takes longer
+- 🔋 **Battery Efficient:** No HTTP overhead (headers, TLS handshake, etc.)
+- 🎯 **More Precise:** Only checks network reachability, not server logic
+- 🛡️ **Prevents Errors:** Detects foreign WiFi networks before sync error occurs
+
+**When does the check fail?**
+- ❌ Server offline/unreachable
+- ❌ Wrong WiFi network (e.g. public café WiFi)
+- ❌ Network not ready yet (DHCP/routing delay after WiFi connect)
+- ❌ VPN blocks server access
+- ❌ No WebDAV server URL configured
+
+### Sync Behavior by Trigger Type
+
+| Trigger | When server not reachable | On successful sync | Throttling |
+|---------|--------------------------|-------------------|------------|
+| Manual Sync | Toast: "Server not reachable" | Toast: "✅ Synced: X notes" | None |
+| Auto-Sync (onResume) | Silent abort (no toast) | Toast: "✅ Synced: X notes" | Max. 1x/min |
+| Background Sync | Silent abort (no toast) | Silent (LocalBroadcast only) | 15/30/60 min |
+| WiFi-Connect Sync | Silent abort (no toast) | Silent (LocalBroadcast only) | SSID-based |
+
+---
+
+## <20>🔋 Battery Optimization
+
+### Usage Analysis
+
+| Component | Frequency | Usage | Details |
+|------------|----------|-----------|---------|
+| WorkManager Wakeup | Every 30 min | ~0.15 mAh | System wakes up |
+| Network Check | 48x/day | ~0.03 mAh | Gateway IP check |
+| WebDAV Sync | 2-3x/day | ~1.5 mAh | Only when changes |
+| **Total** | - | **~12 mAh/day** | **~0.4%** at 3000mAh |
+
+### Optimizations
+
+1. **IP Caching**
+   ```kotlin
+   private var cachedServerIP: String? = null
+   // DNS lookup only once at start, not every check
+   ```
+
+2. **Throttling**
+   ```kotlin
+   private var lastSyncTime = 0L
+   private const val MIN_SYNC_INTERVAL_MS = 60_000L  // Max 1 sync/min
+   ```
+
+3. **Conditional Logging**
+   ```kotlin
+   object Logger {
+       fun d(tag: String, msg: String) {
+           if (BuildConfig.DEBUG) Log.d(tag, msg)
+       }
+   }
+   ```
+
+4. **Network Constraints**
+   - WiFi only (not mobile data)
+   - Only when server is reachable
+   - No permanent listeners
+

+
+## 📦 WebDAV Sync Details
+
+### Upload Flow
+
+```kotlin
+suspend fun uploadNotes(): Int {
+    val localNotes = storage.loadAllNotes()
+    var uploadedCount = 0
+    
+    for (note in localNotes) {
+        if (note.syncStatus == SyncStatus.PENDING) {
+            val jsonContent = note.toJson()
+            val remotePath = "$serverUrl/${note.id}.json"
+            
+            sardine.put(remotePath, jsonContent.toByteArray())
+            
+            note.syncStatus = SyncStatus.SYNCED
+            storage.saveNote(note)
+            uploadedCount++
+        }
+    }
+    
+    return uploadedCount
+}
+```
+
+### Download Flow
+
+```kotlin
+suspend fun downloadNotes(): DownloadResult {
+    val remoteFiles = sardine.list(serverUrl)
+    var downloadedCount = 0
+    var conflictCount = 0
+    
+    for (file in remoteFiles) {
+        if (!file.name.endsWith(".json")) continue
+        
+        val content = sardine.get(file.href)
+        val remoteNote = Note.fromJson(content)
+        val localNote = storage.loadNote(remoteNote.id)
+        
+        if (localNote == null) {
+            // New note from server
+            storage.saveNote(remoteNote)
+            downloadedCount++
+        } else if (localNote.modifiedAt < remoteNote.modifiedAt) {
+            // Server has newer version
+            storage.saveNote(remoteNote)
+            downloadedCount++
+        } else if (localNote.modifiedAt > remoteNote.modifiedAt) {
+            // Local version is newer → Conflict
+            resolveConflict(localNote, remoteNote)
+            conflictCount++
+        }
+    }
+    
+    return DownloadResult(downloadedCount, conflictCount)
+}
+```
+
+### Conflict Resolution
+
+Strategy: **Last-Write-Wins** with **Conflict Copy**
+
+```kotlin
+fun resolveConflict(local: Note, remote: Note) {
+    // Rename remote note (conflict copy)
+    val conflictNote = remote.copy(
+        id = "${remote.id}_conflict_${System.currentTimeMillis()}",
+        title = "${remote.title} (Conflict)"
+    )
+    
+    storage.saveNote(conflictNote)
+    
+    // Local note remains
+    local.syncStatus = SyncStatus.SYNCED
+    storage.saveNote(local)
+}
+```
+
+---
+
+## 🔔 Notifications
+
+### Notification Channels
+
+```kotlin
+val channel = NotificationChannel(
+    "notes_sync_channel",
+    "Notes Synchronization",
+    NotificationManager.IMPORTANCE_DEFAULT
+)
+```
+
+### Success Notification
+
+```kotlin
+fun showSyncSuccess(context: Context, count: Int) {
+    val intent = Intent(context, MainActivity::class.java)
+    val pendingIntent = PendingIntent.getActivity(context, 0, intent, FLAGS)
+    
+    val notification = NotificationCompat.Builder(context, CHANNEL_ID)
+        .setContentTitle("Sync successful")
+        .setContentText("$count notes synchronized")
+        .setContentIntent(pendingIntent)  // Click opens app
+        .setAutoCancel(true)              // Dismiss on click
+        .build()
+    
+    notificationManager.notify(NOTIFICATION_ID, notification)
+}
+```
+
+---
+
+## 🛡️ Permissions
+
+The app requires **minimal permissions**:
+
+```xml
+<!-- Network -->
+<uses-permission android:name="android.permission.INTERNET" />
+<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
+<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
+<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
+
+<!-- Notifications -->
+<uses-permission android:name="android.permission.POST_NOTIFICATIONS" />
+
+<!-- Boot Receiver -->
+<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
+
+<!-- Battery Optimization (optional) -->
+<uses-permission android:name="android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS" />
+```
+
+**No Location Permissions!**  
+Earlier versions required `ACCESS_FINE_LOCATION` for SSID detection. Now we use Gateway IP Comparison.
+

+## <EFBFBD> Sync-Trigger Übersicht
+
+Die App verwendet **4 verschiedene Sync-Trigger** mit unterschiedlichen Anwendungsfällen:
+
+| Trigger | Datei | Funktion | Wann? | Pre-Check? |
+|---------|-------|----------|-------|------------|
+| **1. Manueller Sync** | `MainActivity.kt` | `triggerManualSync()` | User klickt auf Sync-Button im Menü | ✅ Ja |
+| **2. Auto-Sync (onResume)** | `MainActivity.kt` | `triggerAutoSync()` | App wird geöffnet/fortgesetzt | ✅ Ja |
+| **3. Hintergrund-Sync (Periodic)** | `SyncWorker.kt` | `doWork()` | Alle 15/30/60 Minuten (konfigurierbar) | ✅ Ja |
+| **4. WiFi-Connect Sync** | `NetworkMonitor.kt` → `SyncWorker.kt` | `triggerWifiConnectSync()` | WiFi an/SSID-Wechsel | ✅ Ja |
+
+### Server-Erreichbarkeits-Check (Pre-Check)
+
+**Alle 4 Sync-Trigger** verwenden vor dem eigentlichen Sync einen **Pre-Check**:
+
+```kotlin
+// WebDavSyncService.kt - isServerReachable()
+suspend fun isServerReachable(): Boolean = withContext(Dispatchers.IO) {
+    return@withContext try {
+        Socket().use { socket ->
+            socket.connect(InetSocketAddress(host, port), 2000)  // 2s Timeout
+        }
+        true
+    } catch (e: Exception) {
+        Logger.d(TAG, "Server not reachable: ${e.message}")
+        false
+    }
+}
+```
+
+**Warum Socket-Check statt HTTP-Request?**
+- ⚡ **Schneller:** Socket-Connect ist instant, HTTP-Request dauert länger
+- 🔋 **Akkuschonender:** Kein HTTP-Overhead (Headers, TLS Handshake, etc.)
+- 🎯 **Präziser:** Prüft nur Netzwerk-Erreichbarkeit, nicht Server-Logik
+- 🛡️ **Verhindert Fehler:** Erkennt fremde WiFi-Netze bevor Sync-Fehler entsteht
+
+**Wann schlägt der Check fehl?**
+- ❌ Server offline/nicht erreichbar
+- ❌ Falsches WiFi-Netzwerk (z.B. öffentliches Café-WiFi)
+- ❌ Netzwerk noch nicht bereit (DHCP/Routing-Delay nach WiFi-Connect)
+- ❌ VPN blockiert Server-Zugriff
+- ❌ Keine WebDAV-Server-URL konfiguriert
+
+### Sync-Verhalten nach Trigger-Typ
+
+| Trigger | Bei Server nicht erreichbar | Bei erfolgreichem Sync | Throttling |
+|---------|----------------------------|----------------------|------------|
+| Manueller Sync | Toast: "Server nicht erreichbar" | Toast: "✅ Gesynct: X Notizen" | Keins |
+| Auto-Sync (onResume) | Silent abort (kein Toast) | Toast: "✅ Gesynct: X Notizen" | Max. 1x/Min |
+| Hintergrund-Sync | Silent abort (kein Toast) | Silent (LocalBroadcast only) | 15/30/60 Min |
+| WiFi-Connect Sync | Silent abort (kein Toast) | Silent (LocalBroadcast only) | SSID-basiert |

-# GitHub Actions Setup Guide
-
-This guide explains how to set up the GitHub Actions workflow for automated APK builds with proper signing.
-
-## Overview
-
-The workflow in `.github/workflows/build-production-apk.yml` automatically:
- Builds signed APKs on every push to `main`
- Generates version numbers using `YYYY.MM.DD` + build number
- Creates 3 APK variants (universal, arm64-v8a, armeabi-v7a)
- Creates GitHub releases with all APKs attached
-
-## Prerequisites
-
- GitHub CLI (`gh`) installed
- Java 17+ installed (for keytool)
- Git repository initialized with GitHub remote
-
-## Step 1: Generate Signing Keystore
-
-⚠️ **IMPORTANT**: Store the keystore securely! Without it, you cannot publish updates to your app.
-
-```bash
-# Navigate to project root
-cd /path/to/simple-notes-sync
-
-# Generate keystore (replace values as needed)
-keytool -genkey -v \
-  -keystore android/app/simple-notes-release.jks \
-  -keyalg RSA \
-  -keysize 2048 \
-  -validity 10000 \
-  -alias simple-notes
-
-# You will be prompted for:
-# - Keystore password (remember this!)
-# - Key password (remember this!)
-# - Your name, organization, etc.
-```
-
-**Store these securely:**
- Keystore password
- Key password
- Alias: `simple-notes`
- Keystore file: `android/app/simple-notes-release.jks`
-
-⚠️ **BACKUP**: Make a backup of the keystore file in a secure location (NOT in the repository).
-
-## Step 2: Base64 Encode Keystore
-
-```bash
-# Create base64 encoded version
-base64 android/app/simple-notes-release.jks > simple-notes-release.jks.b64
-
-# Or on macOS:
-base64 -i android/app/simple-notes-release.jks -o simple-notes-release.jks.b64
-```
-
-## Step 3: Set GitHub Secrets
-
-Using GitHub CLI (recommended):
-
-```bash
-# Set KEYSTORE_BASE64 secret
-gh secret set KEYSTORE_BASE64 < simple-notes-release.jks.b64
-
-# Set KEYSTORE_PASSWORD (will prompt for input)
-gh secret set KEYSTORE_PASSWORD
-
-# Set KEY_PASSWORD (will prompt for input)
-gh secret set KEY_PASSWORD
-
-# Set KEY_ALIAS (value: simple-notes)
-printf "simple-notes" | gh secret set KEY_ALIAS
-```
-
-Or manually via GitHub web interface:
-1. Go to repository Settings → Secrets and variables → Actions
-2. Click "New repository secret"
-3. Add these secrets:
-   - `KEYSTORE_BASE64`: Paste content of `simple-notes-release.jks.b64`
-   - `KEYSTORE_PASSWORD`: Your keystore password
-   - `KEY_PASSWORD`: Your key password
-   - `KEY_ALIAS`: `simple-notes`
-
-## Step 4: Verify Setup
-
-```bash
-# Check secrets are set
-gh secret list
-
-# Expected output:
-# KEYSTORE_BASE64  Updated YYYY-MM-DD
-# KEYSTORE_PASSWORD  Updated YYYY-MM-DD
-# KEY_PASSWORD  Updated YYYY-MM-DD
-# KEY_ALIAS  Updated YYYY-MM-DD
-```
-
-## Step 5: Cleanup
-
-```bash
-# Remove sensitive files (they're in .gitignore, but double-check)
-rm simple-notes-release.jks.b64
-rm -f android/key.properties  # Generated by workflow
-
-# Verify keystore is NOT tracked by git
-git status | grep -i jks
-# Should return nothing
-```
-
-## Step 6: Trigger First Build
-
-```bash
-# Commit and push to main
-git add .
-git commit -m "🚀 feat: Add GitHub Actions deployment workflow"
-git push origin main
-
-# Or manually trigger workflow
-gh workflow run build-production-apk.yml
-```
-
-## Verification
-
-1. Go to GitHub repository → Actions tab
-2. Check workflow run status
-3. Once complete, go to Releases tab
-4. Verify release was created with 3 APK variants
-5. Download and test one of the APKs
-
-## Troubleshooting
-
-### Build fails with "Keystore not found"
- Check `KEYSTORE_BASE64` secret is set correctly
- Verify base64 encoding was done without line breaks
-
-### Build fails with "Incorrect password"
- Verify `KEYSTORE_PASSWORD` and `KEY_PASSWORD` are correct
- Re-set secrets if needed
-
-### APK files not found
- Check build logs for errors in assembleRelease step
- Verify APK output paths match workflow expectations
-
-### Updates don't work
- Ensure you're using the same keystore for all builds
- Verify `applicationId` in build.gradle.kts matches
-
-## Security Notes
-
- ✅ Keystore is base64-encoded in GitHub secrets (secure)
- ✅ Passwords are stored in GitHub secrets (encrypted)
- ✅ `key.properties` and `.jks` files are in `.gitignore`
- ⚠️ Never commit keystore files to repository
- ⚠️ Keep backup of keystore in secure location
- ⚠️ Don't share keystore passwords
-
-## Versioning
-
-Versions follow this pattern:
- **Version Name**: `YYYY.MM.DD` (e.g., `2025.01.15`)
- **Version Code**: GitHub run number (e.g., `42`)
- **Release Tag**: `vYYYY.MM.DD-prod.BUILD` (e.g., `v2025.01.15-prod.42`)
-
-This ensures:
- Semantic versioning based on release date
- Incremental version codes for Play Store compatibility
- Clear distinction between builds
-
-## APK Variants
-
-The workflow generates 3 APK variants:
-
-1. **Universal APK** (~5 MB)
-   - Works on all devices
-   - Larger file size
-   - Recommended for most users
-
-2. **arm64-v8a APK** (~3 MB)
-   - For modern devices (2018+)
-   - Smaller, faster
-   - 64-bit ARM processors
-
-3. **armeabi-v7a APK** (~3 MB)
-   - For older devices
-   - 32-bit ARM processors
-
-Users can choose based on their device - Obtanium auto-updates work with all variants.

+> Step-by-step installation and setup guide
+
+**🌍 Languages:** [Deutsch](QUICKSTART.md) · **English**
+
+---
+
+## Prerequisites
+
+- ✅ Android 8.0+ smartphone/tablet
+- ✅ WiFi connection
+- ✅ Own server with Docker (optional - for self-hosting)
+
+---
+
+## Option 1: With own server (Self-Hosted) 🏠
+
+### Step 1: Setup WebDAV Server
+
+On your server (e.g. Raspberry Pi, NAS, VPS):
+
+```bash
+# Clone repository
+git clone https://github.com/inventory69/simple-notes-sync.git
+cd simple-notes-sync/server
+
+# Configure environment variables
+cp .env.example .env
+nano .env
+```
+
+**Adjust in `.env`:**
+```env
+WEBDAV_PASSWORD=your-secure-password-here
+```
+
+**Start server:**
+```bash
+docker compose up -d
+```
+
+**Find IP address:**
+```bash
+ip addr show | grep "inet " | grep -v 127.0.0.1
+```
+
+➡️ **Note down:** `http://YOUR-SERVER-IP:8080/`
+
+---
+
+### Step 2: Install App
+
+1. **Download APK:** [Latest version](https://github.com/inventory69/simple-notes-sync/releases/latest)
+   - Choose: `simple-notes-sync-vX.X.X-standard-universal.apk`
+   
+2. **Allow installation:**
+   - Android: Settings → Security → Enable "Unknown sources" for your browser
+   
+3. **Open and install APK**
+
+---
+
+### Step 3: Configure App
+

+2. **Open settings** (⚙️ icon top right)
+
+3. **Configure server settings:**
+   
+   | Field | Value |
+   |------|------|
+   | **WebDAV Server URL** | `http://YOUR-SERVER-IP:8080/` |
+   | **Username** | `noteuser` |
+   | **Password** | (your password from `.env`) |
+   | **Gateway SSID** | Name of your WiFi network |
+
+4. **Press "Test connection"**
+   - ✅ Success? → Continue to step 4
+   - ❌ Error? → See [Troubleshooting](#troubleshooting)
+
+5. **Enable auto-sync** (toggle switch)
+
+6. **Choose sync interval:**
+   - **15 min** - Maximum currency (~0.8% battery/day)
+   - **30 min** - Recommended (~0.4% battery/day) ⭐
+   - **60 min** - Maximum battery life (~0.2% battery/day)
+
+---
+
+### Step 4: Create First Note
+
+1. Back to main view (← arrow)
+
+2. **"Add note"** (+ icon)
+
+3. Enter title and text
+
+4. **Save** (💾 icon)
+
+5. **Wait for auto-sync** (or manually: ⚙️ → "Sync now")
+
+🎉 **Done!** Your notes will be automatically synchronized!
+
+---
+
+## Option 2: Local notes only (no server) 📱
+
+You can also use Simple Notes **without a server**:
+
+1. **Install app** (see step 2 above)
+
+2. **Use without server configuration:**
+   - Notes are only stored locally

+For reliable auto-sync:
+
+1. **Settings** → **Apps** → **Simple Notes Sync**
+
+2. **Battery** → **Battery usage**
+
+3. Select: **"Don't optimize"** or **"Unrestricted"**
+
+💡 **Note:** Android Doze Mode may still delay sync in standby (~60 min). This is normal and affects all apps.
+
+---
+
+## 📊 Sync Intervals in Detail
+
+| Interval | Syncs/day | Battery/day | Battery/sync | Use case |
+|-----------|-----------|----------|-----------|----------------|
+| **15 min** | ~96 | ~0.8% (~23 mAh) | ~0.008% | ⚡ Maximum currency (multiple devices) |
+| **30 min** | ~48 | ~0.4% (~12 mAh) | ~0.008% | ✓ **Recommended** - balanced |

+   - Smartphone and server must be on same network
+   - Check SSID in app settings
+
+3. **IP address correct?**
+   ```bash
+   ip addr show | grep "inet "
+   # Check if IP in URL matches
+   ```
+
+4. **Firewall?**
+   ```bash
+   # Open port 8080 (if firewall active)
+   sudo ufw allow 8080/tcp
+   ```
+
+5. **Check server logs:**
+   ```bash
+   docker compose logs -f
+   ```
+
+---
+
+### Auto-sync not working
+
+**Problem:** Notes are not automatically synchronized
+
+**Solutions:**
+
+1. **Auto-sync enabled?**
+   - ⚙️ Settings → Toggle "Auto-sync" must be **ON**
+
+2. **Battery optimization disabled?**
+   - See [Disable Battery Optimization](#-disable-battery-optimization)
+
+3. **On correct WiFi?**
+   - Sync only works when SSID = Gateway SSID
+   - Check current SSID in Android settings
+
+4. **Test manually:**
+   - ⚙️ Settings → "Sync now"
+   - Works? → Auto-sync should work too
+
+---
+
+### Notes not showing up
+
+**Problem:** After installation, no notes visible even though they exist on server
+
+**Solution:**
+
+1. **Manually sync once:**
+   - ⚙️ Settings → "Sync now"
+
+2. **Check server data:**
+   ```bash
+   docker compose exec webdav ls -la /data/
+   # Should show .json files
+   ```
+
+---
+
+### Sync errors
+
+**Problem:** Error message during sync
+
+**Solutions:**
+
+1. **"401 Unauthorized"** → Wrong password
+   - Check password in app settings
+   - Compare with `.env` on server
+
+2. **"404 Not Found"** → Wrong URL
+   - Should end with `/` (e.g. `http://192.168.1.100:8080/`)
+

-# APK signieren
-# Play Store Upload oder Direct Install
-```
-
-## 🔐 Security
-
-**Entwicklung:**
- ✅ HTTP Basic Auth
- ✅ Nur im lokalen Netzwerk
-
-**Produktion:**
- ⚠️ HTTPS mit SSL/TLS (empfohlen)
- ⚠️ Starkes Passwort
- ⚠️ Firewall-Regeln
- ⚠️ VPN für externen Zugriff
-
-## 🐛 Troubleshooting
-
-### Server startet nicht
-
-```bash
-# Port bereits belegt?
-sudo netstat -tlnp | grep 8080
-
-# Logs checken
-docker-compose logs webdav
-```
-
-### Android kann nicht verbinden
-
- Ist Android im gleichen WLAN?
- Ist die Server-IP korrekt?
- Firewall blockiert Port 8080?
- Credentials korrekt?
-
-```bash
-# Ping zum Server
-ping YOUR_SERVER_IP
-
-# Port erreichbar?
-telnet YOUR_SERVER_IP 8080
-```

+# Lokale Gradle Builds mit Release-Signierung
+
+Dieses Dokument erklärt, wie du lokal signierte APKs erstellst, die mit den GitHub Release-APKs kompatibel sind.
+
+## Problem
+
+- **GitHub Actions** erstellt signierte Release-APKs mit dem Production-Keystore
+- **Lokale Debug-Builds** verwenden einen temporären Debug-Key
+- ❌ **Resultat:** Nutzer können lokale Debug-APKs NICHT über Release-APKs installieren (Signature Mismatch!)
+
+## Lösung: Lokale Release-Builds mit Production-Key
+
+### 1️⃣ Keystore-Konfiguration einrichten
+
+Du hast bereits den Keystore: `/android/app/simple-notes-release.jks`
+
+Erstelle eine `key.properties` Datei im `/android/` Ordner:
+
+```bash
+cd /home/liq/gitProjects/simple-notes-sync/android
+cp key.properties.example key.properties
+```
+
+Bearbeite `key.properties` mit den echten Werten:
+
+```properties
+storeFile=simple-notes-release.jks
+storePassword=<dein-keystore-password>
+keyAlias=<dein-key-alias>
+keyPassword=<dein-key-password>
+```
+
+**Wichtig:** Die Werte müssen **exakt** mit den GitHub Secrets übereinstimmen:
+- `KEYSTORE_PASSWORD` → `storePassword`
+- `KEY_ALIAS` → `keyAlias`
+- `KEY_PASSWORD` → `keyPassword`
+
+### 2️⃣ Lokal signierte Release-APKs bauen
+
+```bash
+cd android
+./gradlew assembleStandardRelease
+```
+
+Die signierten APKs findest du dann hier:
+```
+android/app/build/outputs/apk/standard/release/
+├── app-standard-universal-release.apk
+├── app-standard-arm64-v8a-release.apk
+└── app-standard-armeabi-v7a-release.apk
+```
+
+### 3️⃣ F-Droid Flavor bauen (optional)
+
+```bash
+./gradlew assembleFdroidRelease
+```
+
+### 4️⃣ Beide Flavors gleichzeitig bauen
+
+```bash
+./gradlew assembleStandardRelease assembleFdroidRelease
+```
+
+## Verifizierung der Signatur
+
+Um zu prüfen, ob dein lokaler Build die gleiche Signatur wie die Release-Builds hat:
+
+```bash
+# Signatur von lokalem Build anzeigen
+keytool -printcert -jarfile app/build/outputs/apk/standard/release/app-standard-universal-release.apk
+
+# Signatur von GitHub Release-APK anzeigen (zum Vergleich)
+keytool -printcert -jarfile ~/Downloads/simple-notes-sync-v1.1.0-standard-universal.apk
+```
+
+Die **SHA256** Fingerprints müssen **identisch** sein!
+
+## Troubleshooting
+
+### ❌ Build schlägt fehl: "Keystore not found"
+
+**Problem:** `key.properties` oder Keystore-Datei fehlt
+
+**Lösung:** 
+1. Prüfe, ob `key.properties` existiert: `ls -la key.properties`
+2. Prüfe, ob der Keystore existiert: `ls -la app/simple-notes-release.jks`
+
+### ❌ "Signature mismatch" beim Update
+
+**Problem:** Der lokale Build verwendet einen anderen Key als die Release-Builds
+
+**Lösung:**
+1. Vergleiche die Signaturen mit `keytool` (siehe oben)
+2. Stelle sicher, dass `key.properties` die **exakten** GitHub Secret-Werte enthält
+3. Deinstalliere die alte Version und installiere die neue (als letzter Ausweg)
+
+### ❌ Build verwendet Debug-Signatur
+
+**Problem:** `build.gradle.kts` findet `key.properties` nicht
+
+**Lösung:**
+```bash
+# Prüfe, ob die Datei im richtigen Verzeichnis liegt
+ls -la android/key.properties  # ✅ Richtig
+ls -la android/app/key.properties  # ❌ Falsch
+```
+
+## Sicherheitshinweise
+
+⚠️ **NIEMALS** diese Dateien committen:
+- `key.properties` (in `.gitignore`)
+- `*.jks` / `*.keystore` (in `.gitignore`)
+
+✅ **Schon in `.gitignore`:**
+```gitignore
+key.properties
+*.jks
+*.keystore
+```
+
+⚠️ Die GitHub Secrets (`KEYSTORE_PASSWORD`, etc.) und die lokale `key.properties` müssen **synchron** bleiben!
+
+## Workflow-Vergleich
+
+### GitHub Actions Build
+```yaml
+- Lädt Keystore aus Base64 Secret
+- Erstellt key.properties aus Secrets
+- Baut mit: ./gradlew assembleStandardRelease
+- ✅ Produktions-signiert
+```
+
+### Lokaler Build
+```bash
+# Mit key.properties konfiguriert:
+./gradlew assembleStandardRelease
+# ✅ Produktions-signiert (gleiche Signatur wie GitHub!)
+
+# Ohne key.properties:
+./gradlew assembleStandardRelease
+# ⚠️ Debug-signiert (inkompatibel mit Releases!)
+```
+
+## Quick Reference
+
+```bash
+# Release-APK bauen (signiert, klein, optimiert)
+./gradlew assembleStandardRelease
+
+# Debug-APK bauen (unsigniert, groß, debuggable)
+./gradlew assembleStandardDebug
+
+# APK per HTTP Server verteilen
+cd app/build/outputs/apk/standard/release
+python3 -m http.server 8892

+## 📜 Verfügbare Scripts
+
+### 1. `create-keystore.fish` - Neuen Release-Keystore erstellen
+
+**Wann verwenden:**
+- ✅ Erstmaliges Setup des Projekts
+- ✅ Keystore-Passwort vergessen
+- ✅ Keystore beschädigt oder verloren
+- ❌ **NICHT** verwenden, wenn bereits User existieren (macht alte APKs inkompatibel!)
+
+**Verwendung:**
+```bash
+cd /home/liq/gitProjects/simple-notes-sync/android
+./scripts/create-keystore.fish
+```
+
+**Das Script:**
+1. Erstellt einen neuen 4096-Bit RSA-Keystore
+2. Generiert `app/simple-notes-release.jks`
+3. Erstellt `key.properties` mit den Zugangsdaten
+4. Zeigt Base64-kodierten Keystore für GitHub Secrets
+5. Gibt SHA256-Fingerprint zur Verifikation aus
+
+**Output:**
+- ✅ `app/simple-notes-release.jks` - Der Keystore
+- ✅ `key.properties` - Lokale Signing-Konfiguration
+- 📋 GitHub Secrets zum Kopieren
+
+---
+
+### 2. `verify-secrets.fish` - GitHub Secrets & Keystore verifizieren
+
+**Wann verwenden:**
+- ✅ Nach `create-keystore.fish` zur Verifikation
+- ✅ Vor einem Release-Build zum Troubleshooting
+- ✅ Um zu prüfen ob alles korrekt konfiguriert ist
+
+**Verwendung:**
+```bash
+cd /home/liq/gitProjects/simple-notes-sync/android
+./scripts/verify-secrets.fish
+```
+
+**Das Script prüft:**
+- GitHub CLI Installation & Authentifizierung
+- Ob alle 4 erforderlichen GitHub Secrets gesetzt sind
+- Ob `key.properties` lokal existiert
+- Ob der Keystore existiert
+- Zeigt SHA256-Fingerprint des Keystores
+
+**Output:**
+- ✅ Status aller Secrets
+- ✅ Status der lokalen Konfiguration
+- 💡 Empfehlungen bei Problemen
+
+---
+
+### 3. `build-release-local.fish` - Lokal signierte Release-APKs bauen
+
+**Wann verwenden:**
+- ✅ Lokale Test-APKs erstellen, die mit Releases kompatibel sind
+- ✅ APKs vor dem GitHub Release testen
+- ✅ Schneller als GitHub Actions für Tests
+
+**Voraussetzung:**
+- `key.properties` muss existieren (via `create-keystore.fish` erstellt)
+
+**Verwendung:**
+```bash
+cd /home/liq/gitProjects/simple-notes-sync/android
+./scripts/build-release-local.fish
+```
+
+**Interaktive Auswahl:**
+1. Standard Flavor (empfohlen)
+2. F-Droid Flavor
+3. Beide Flavors
+
+**Output:**
+- `app/build/outputs/apk/standard/release/` - Signierte Standard APKs
+- `app/build/outputs/apk/fdroid/release/` - Signierte F-Droid APKs
+
+---
+
+## 🚀 Kompletter Workflow (von 0 auf Release)
+
+### Erstmaliges Setup
+
+```bash
+cd /home/liq/gitProjects/simple-notes-sync/android
+
+# 1. Keystore erstellen (mit automatischer GitHub Secrets-Konfiguration!)
+./scripts/create-keystore.fish
+# → Folge den Anweisungen, speichere die Passwörter!
+# → GitHub Secrets werden automatisch via GitHub CLI gesetzt
+
+# 2. Verifiziere die Konfiguration
+./scripts/verify-secrets.fish
+# → Prüft ob alle Secrets gesetzt sind
+# → Zeigt Keystore-Informationen
+
+# 3. Teste lokalen Build
+./scripts/build-release-local.fish
+# → Wähle "1" für Standard Flavor
+
+# 4. Verifiziere Signatur
+keytool -printcert -jarfile app/build/outputs/apk/standard/release/app-standard-universal-release.apk
+```
+
+### Vor jedem Release
+
+```bash
+# 1. Code committen und pushen
+git add .
+git commit -m "✨ Neue Features"
+git push origin main
+
+# 2. GitHub Actions erstellt automatisch Release
+# → Workflow läuft: .github/workflows/build-production-apk.yml
+# → Erstellt Release mit signierten APKs
+
+# Optional: Lokalen Test-Build vorher
+./scripts/build-release-local.fish
+```
+
+---
+
+## 🔐 Sicherheitshinweise
+
+### ⚠️ Diese Dateien NIEMALS committen:
+- `key.properties` - Enthält Keystore-Passwörter
+- `*.jks` / `*.keystore` - Der Keystore selbst
+- Beide sind bereits in `.gitignore`
+
+### ✅ Diese Werte sicher speichern:
+- Keystore-Passwort
+- Key-Alias
+- Key-Passwort
+- Base64-kodierter Keystore (für GitHub Secrets)
+
+**Empfehlung:** Nutze einen Passwort-Manager (Bitwarden, 1Password, etc.)
+
+---
+
+## 🛠️ Troubleshooting
+
+### "Keystore not found"
+```bash
+# Prüfe ob Keystore existiert
+ls -la app/simple-notes-release.jks
+
+# Falls nicht: Neu erstellen
+./scripts/create-keystore.fish
+```
+
+### "key.properties not found"
+```bash
+# Prüfe ob Datei existiert
+ls -la key.properties
+
+# Falls nicht: Keystore neu erstellen oder manuell anlegen
+./scripts/create-keystore.fish
+```
+
+### "Signature mismatch" beim App-Update
+**Problem:** Lokaler Build hat andere Signatur als GitHub Release
+
+**Ursache:** Unterschiedliche Keystores oder Passwörter
+
+**Lösung:**
+1. Vergleiche SHA256-Fingerprints:
+   ```bash
+   # Lokal
+   keytool -list -v -keystore app/simple-notes-release.jks
+   
+   # GitHub Release-APK
+   keytool -printcert -jarfile ~/Downloads/simple-notes-v1.1.0.apk
+   ```
+2. Müssen **identisch** sein!
+3. Falls nicht: GitHub Secrets mit lokaler `key.properties` synchronisieren
+
