-# Firebase Setup Guide for Sage
-
-## Step 1: Create Firebase Project
-
-1. Go to [Firebase Console](https://console.firebase.google.com/)
-2. Click "Add project"
-3. Enter project name: `sage-kitchen-management`
-4. Disable Google Analytics (optional for this app)
-5. Click "Create project"
-
-## Step 2: Add Android App
-
-1. In Firebase Console, click the Android icon to add an Android app
-2. Enter package name: `com.github.mystiatech.sage` (must match exactly!)
-3. App nickname: `Sage` (optional)
-4. Debug signing certificate SHA-1: (optional, skip for now)
-5. Click "Register app"
-
-## Step 3: Download Configuration File
-
-1. Download the `google-services.json` file
-2. Place it in: `android/app/google-services.json`
-
-## Step 4: Set up Firestore Database
-
-1. In Firebase Console, go to "Build" → "Firestore Database"
-2. Click "Create database"
-3. Choose "Start in test mode" for development
-4. Select a Firestore location (e.g., `us-central`)
-5. Click "Enable"
-
-### Security Rules (update after testing)
-
-For development/testing, use test mode rules:
-```
-rules_version = '2';
-service cloud.firestore {
-  match /databases/{database}/documents {
-    match /{document=**} {
-      allow read, write: if request.time < timestamp.date(2025, 12, 31);
-    }
-  }
-}
-```
-
-For production, update to:
-```
-rules_version = '2';
-service cloud.firestore {
-  match /databases/{database}/documents {
-    // Allow anyone to read household data by code
-    match /households/{householdId} {
-      allow read: if true;
-      allow create: if true;
-      allow update: if true;
-      allow delete: if request.auth != null;
-
-      // Allow household members to manage items
-      match /items/{itemId} {
-        allow read: if true;
-        allow write: if true;
-      }
-    }
-  }
-}
-```
-
-## Step 5: Update Android Build Files (Already Done)
-
-The following files need to be updated (will be done automatically):
-
-1. `android/build.gradle` - Add Google Services plugin
-2. `android/app/build.gradle` - Apply Google Services plugin
-
-## Step 6: Initialize Firebase in App
-
-The app will automatically initialize Firebase on startup.
-
-## Firestore Data Structure
-
-```
-households (collection)
-  └── {householdCode} (document)
-      ├── id: string
-      ├── name: string
-      ├── ownerName: string
-      ├── createdAt: string (ISO 8601)
-      └── members: array<string>
-      └── items (subcollection)
-          └── {itemKey} (document)
-              ├── name: string
-              ├── barcode: string?
-              ├── quantity: number
-              ├── unit: string?
-              ├── purchaseDate: string (ISO 8601)
-              ├── expirationDate: string (ISO 8601)
-              ├── locationIndex: number
-              ├── category: string?

-              ├── notes: string?
-              ├── userId: string?
-              ├── householdId: string
-              ├── lastModified: string (ISO 8601)
-              └── syncedToCloud: boolean
-```
-
-## Testing
-
-1. Create a household on Device A
-2. Note the 6-character code
-3. Join the household from Device B using the code
-4. Add items on Device A → should appear on Device B
-5. Add items on Device B → should appear on Device A
-
-## Troubleshooting
-
-- **"google-services.json not found"**: Make sure file is in `android/app/` directory
-- **Build errors**: Run `flutter clean && flutter pub get`
-- **Permission denied**: Check Firestore security rules in Firebase Console
-- **Items not syncing**: Check internet connection and Firebase Console logs

+# Release Guide for Sage - Google Play & F-Droid
+
+## 🔐 Step 1: Create Signing Key (Required for Google Play)
+
+### Generate Keystore:
+```bash
+# Run this in your terminal (uses Java keytool)
+cd android/app
+keytool -genkey -v -keystore sage-release-key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias sage-key
+```
+
+**When prompted, enter:**

+
+### Update build.gradle.kts:
+
+Add this to `android/app/build.gradle.kts` before `android {`:
+
+```kotlin
+// Load keystore properties
+val keystorePropertiesFile = rootProject.file("key.properties")
+val keystoreProperties = Properties()
+if (keystorePropertiesFile.exists()) {
+    keystoreProperties.load(FileInputStream(keystorePropertiesFile))
+}
+```
+
+Then update `signingConfigs` inside `android {`:
+
+```kotlin
+signingConfigs {
+    create("release") {
+        keyAlias = keystoreProperties["keyAlias"] as String
+        keyPassword = keystoreProperties["keyPassword"] as String
+        storeFile = file(keystoreProperties["storeFile"] as String)
+        storePassword = keystoreProperties["storePassword"] as String
+    }
+}
+```
+
+And update `buildTypes`:
+
+```kotlin
+buildTypes {
+    release {
+        signingConfig = signingConfigs.getByName("release")
+    }
+}
+```
+
+## 📦 Step 2: Build Signed Release APK

+✅ **Open Source:**
+- Code is open source ✓
+- Need to publish to GitHub public repo
+
+✅ **No Proprietary Dependencies:**
+- ❌ **ISSUE:** Firebase is proprietary
+- ❌ Google Services (google-services.json)
+
+### F-Droid Options:
+
+**Option 1: Remove Firebase for F-Droid build** (Recommended)
+- Create build flavor without Firebase
+- F-Droid users get local-only mode
+- No household cloud sync, but everything else works
+
+**Option 2: Fork for F-Droid**
+- Maintain separate F-Droid version
+- Strip out Firebase completely

+
+**Option 3: Skip F-Droid**
+- Focus on Google Play Store only
+- Provide APK downloads from GitHub releases
+
+### To Prepare for F-Droid:
+
+1. **Publish code to GitHub:**
+   ```bash
+   # Create repo at github.com/mystiatech/sage
+   git remote add origin git@github.com:mystiatech/sage.git
+   git push -u origin master
+   ```
+
+2. **Add LICENSE file:**
+   - Choose license (MIT, GPL-3.0, Apache-2.0)
+   - Add LICENSE file to root
+
+3. **Submit to F-Droid:**
+   - Open issue at [fdroiddata](https://gitlab.com/fdroid/fdroiddata/-/issues)
+   - Provide GitHub repo URL
+   - They'll review and add to F-Droid
+
+4. **Or:** Self-host F-Droid repo
+   - Simpler than official F-Droid
+   - Users add your repo to F-Droid app
+
+## 📋 Final Checklist
+
+### Google Play Store:
+- [ ] Create signing key
+- [ ] Configure signing in build.gradle.kts
+- [ ] Build signed AAB
+- [ ] Create screenshots (2-8 images)
+- [ ] Create feature graphic (1024x500)
+- [ ] Write store description
+- [ ] Set up privacy policy hosting
+- [ ] Create developer account ($25)
+- [ ] Upload and submit for review
+
+### F-Droid:
+- [ ] Remove Firebase or create separate build flavor
+- [ ] Publish code to GitHub
+- [ ] Add LICENSE file
+- [ ] Submit to F-Droid (or self-host repo)
+- [ ] Wait for F-Droid review (can take weeks)
+
+### Both:
+- [ ] Test signed release build thoroughly
+- [ ] Verify Firebase works with signed build
+- [ ] Test on multiple devices
+- [ ] Update version number for each release
+
+## 🚀 Quick Start Commands
+
+```bash
+# Build for Google Play (signed AAB)
+flutter build appbundle --release
+
+# Build for testing (signed APK)
+flutter build apk --release
+
+# Check what's in the AAB
+cd build/app/outputs/bundle/release
+unzip -l app-release.aab
+```
+
+## 📱 Version Management
+
+Current version: `1.1.0+2`
+
+For each release:
+1. Update version in `pubspec.yaml`
+2. Format: `MAJOR.MINOR.PATCH+BUILD_NUMBER`
+3. Example: `1.2.0+3` (version 1.2.0, build 3)
+
+## ⚠️ Important Notes
+
+1. **Never lose your signing key!** You can't update the app without it.
+2. **Keep key.properties secure** - don't commit to git
+3. **Test signed builds** before uploading to store
+4. **Firebase requires google-services.json** - make sure it's the real one
+5. **First release takes longer** - usually 1-3 days review
+6. **Updates are faster** - usually hours after first approval
+
+## 🆘 Common Issues
+
+**Build fails with signing error:**
+- Check key.properties exists
+- Verify passwords are correct
+- Make sure storeFile path is relative to android/app/
+
+**Firebase doesn't work in release:**
+- Verify google-services.json is the real one (not placeholder)
+- Check package name matches exactly
+- Enable Firestore in Firebase Console
+
+**Play Store rejects:**
+- Update target SDK to latest (currently 34)
+- Add privacy policy URL
+- Complete content rating
+
+**F-Droid rejects:**
+- Remove all proprietary dependencies
+- Use only FOSS libraries
+- Provide full source code

-# Firebase Configuration Required
-
-## ⚠️ IMPORTANT: Replace google-services.json
-
-The current `google-services.json` file is a **PLACEHOLDER** and will **NOT** work.
-
-### Steps to get your real google-services.json:
-
-1. Follow the instructions in `/FIREBASE_SETUP.md` in the project root
-2. Download the real `google-services.json` from Firebase Console
-3. Replace the file in this directory: `android/app/google-services.json`
-
-### Quick Link:
-[Firebase Console](https://console.firebase.google.com/)
-
-### Package Name (must match):
-```
-com.github.mystiatech.sage
-```
-
-Without the real Firebase configuration file, household sharing will not work across devices!

+
+        <div class="highlight">
+            <strong>TL;DR:</strong> Sage is built privacy-first. Your data stays on YOUR device. Optional cloud sync uses open-source Supabase. We don't sell data, track you, or show ads. Ever.
+        </div>
+
+        <h2>1. Information We Collect</h2>
+        <p>Sage is designed to respect your privacy. Here's what we do and don't collect:</p>
+
+        <h3>Local Data (Stored on Your Device)</h3>
+        <ul>
+            <li><strong>Food inventory items</strong> - names, quantities, expiration dates, barcodes, photos, notes</li>
+            <li><strong>User preferences</strong> - app settings, Discord webhook URL (if configured), household name</li>
+            <li><strong>Household information</strong> - household name, member names (if using household sharing)</li>
+        </ul>
+
+        <h3>Cloud Sync Data (Optional - Supabase)</h3>
+        <p>If you choose to use household sharing features, the following data is synced to Supabase (an open-source backend):</p>
+        <ul>
+            <li>Food inventory items from your household</li>
+            <li>Household name and member names</li>
+            <li>Anonymous authentication tokens (no email or personal info required)</li>
+        </ul>
+
+        <h3>What We DON'T Collect</h3>
+        <ul>
+            <li>❌ No email addresses</li>
+            <li>❌ No phone numbers</li>
+            <li>❌ No location tracking</li>
+            <li>❌ No analytics or usage tracking</li>
+            <li>❌ No advertising IDs</li>
+            <li>❌ No personal identifiable information</li>
+        </ul>
+
+        <h2>2. How We Use Your Information</h2>
+        <p>Your data is used ONLY for these purposes:</p>
+        <ul>
+            <li><strong>Local inventory management</strong> - Track your food items on your device</li>
+            <li><strong>Household sharing</strong> - Sync inventory with family members (if enabled)</li>
+            <li><strong>Expiration notifications</strong> - Send alerts via Discord webhook (if configured by you)</li>
+            <li><strong>Barcode lookup</strong> - Fetch product information from public APIs (Open Food Facts, UPCItemDB)</li>
+        </ul>
+
+        <h2>3. Data Storage & Security</h2>
+
+        <h3>Local Storage (Hive Database)</h3>
+        <p>All your data is stored locally on your device using Hive, an encrypted local database. This data never leaves your device unless you explicitly enable household sharing.</p>
+
+        <h3>Cloud Storage (Supabase - Optional)</h3>
+        <p>If you enable household sharing:</p>
+        <ul>
+            <li>Data is stored in Supabase (open-source Firebase alternative)</li>
+            <li>You can use our hosted Supabase instance OR self-host your own</li>
+            <li>Data is transmitted over HTTPS</li>
+            <li>Anonymous authentication - no email or password required</li>
+        </ul>
+
+        <h2>4. Third-Party Services</h2>
+        <p>Sage may interact with these third-party services:</p>
+
+        <h3>Barcode Lookup APIs</h3>
+        <ul>
+            <li><strong>Open Food Facts</strong> - Free, open database of food products</li>
+            <li><strong>UPCItemDB</strong> - Product information database</li>
+            <li>These services receive ONLY the barcode number when you scan items</li>
+        </ul>
+
+        <h3>Discord Webhooks (Optional)</h3>
+        <p>If you configure a Discord webhook URL, Sage will send expiration notifications to your Discord channel. We don't store or have access to your webhook URL on any server.</p>
+
+        <h3>Supabase (Optional)</h3>
+        <p>If you enable household sharing, your inventory data is synced via Supabase. See their privacy policy at <a href="https://supabase.com/privacy" target="_blank">supabase.com/privacy</a></p>
+
+        <h2>5. Data Sharing</h2>
+        <p><strong>We DO NOT sell, rent, or share your data with anyone.</strong></p>
+        <p>The ONLY data sharing happens when:</p>
+        <ul>
+            <li>You explicitly enable household sharing (data shared with your household members via Supabase)</li>
+            <li>You configure Discord notifications (sent to YOUR Discord webhook)</li>
+        </ul>
+
+        <h2>6. Your Rights & Control</h2>
+        <p>You have complete control over your data:</p>
+        <ul>
+            <li><strong>Delete your data</strong> - Uninstall the app to remove all local data</li>
+            <li><strong>Export your data</strong> - Contact us for a data export (coming soon in-app)</li>
+            <li><strong>Disable cloud sync</strong> - Leave household to stop syncing</li>
+            <li><strong>Self-host</strong> - Run your own Supabase instance for full control</li>
+        </ul>
+
+        <h2>7. Children's Privacy</h2>
+        <p>Sage does not knowingly collect information from children under 13. The app is designed for household management and is intended for use by adults.</p>
+
+        <h2>8. Open Source & Transparency</h2>
+        <p>Sage is 100% FOSS (Free and Open Source Software). You can inspect the entire codebase, including:</p>
+        <ul>
+            <li>How data is stored locally</li>
+            <li>What data is sent to Supabase</li>
+            <li>How barcode APIs are used</li>
+            <li>No hidden tracking or analytics</li>
+        </ul>
+
+        <h2>9. Changes to This Policy</h2>
+        <p>We may update this privacy policy from time to time. We'll notify you of any material changes by updating the "Last Updated" date at the top of this policy.</p>
