+# Trackeep Deployment Guide
+
+## Flexible Deployment Options
+
+Trackeep is designed to work in various deployment scenarios:
+
+### 1. Local Development (localhost)
+```bash
+# Start with default settings
+docker compose up -d
+
+# Frontend will be available via nginx on port 80
+# Backend API on port 8080
+# Frontend automatically detects API URL: http://localhost:8080/api/v1
+```
+
+### 2. Home Network Deployment
+```bash
+# Set your HOST environment variable
+export HOST=192.168.1.100:8080
+
+# Or modify .env
+echo "HOST=192.168.1.100:8080" >> .env
+
+docker compose up -d
+
+# Access from any device on your network
+# Frontend: http://192.168.1.100
+# API: http://192.168.1.100:8080/api/v1
+```
+
+### 3. Domain with Cloudflare/Reverse Proxy
+```bash
+# Set HOST to your domain
+export HOST=yourdomain.com
+
+# Configure CORS for your domain
+export CORS_ALLOWED_ORIGINS=https://yourdomain.com
+
+docker compose up -d
+
+# Configure Cloudflare to proxy:
+# - yourdomain.com → backend:8080
+# - app.yourdomain.com → frontend:80
+```
+
+### 4. Production HTTPS
+```bash
+# Set production mode
+export GIN_MODE=release
+export HOST=yourdomain.com
+export CORS_ALLOWED_ORIGINS=https://yourdomain.com
+
+# Use SSL certificates (via Traefik, Nginx, etc.)
+docker compose up -d
+```
+
+## Environment Variables
+
+### Core Configuration
+- `PORT=8080` - Backend port only
+- `GIN_MODE=debug|release` - Application mode
+- `HOST=` - Auto-detection fallback (optional)
+- `CORS_ALLOWED_ORIGINS=*` - Flexible CORS (restrict in production)
+
+### Removed Variables
+- ❌ `FRONTEND_PORT` - No longer needed
+- ❌ `OAUTH_PORT` - Moved to oauth-service/.env
+- ❌ `VITE_API_URL` - Auto-detected via /api/v1/config
+
+### OAuth Service (Separate)
+See `oauth-service/.env.example` for OAuth-specific configuration.
+
+## API Detection
+
+The frontend automatically detects the API URL by:
+1. Calling `/api/v1/config` endpoint
+2. Using the current request's scheme and host
+3. Falling back to `HOST` environment variable
+4. Final fallback to `localhost:8080`
+
+## Port Management
+
+- **Backend**: Fixed port 8080 (required for API)
+- **Frontend**: No port mapping (uses nginx:80 internally)
+- **OAuth**: Separate service on port 9090
+- **Database**: Port 5432 (internal to Docker network)
+
+This flexibility allows Trackeep to adapt to any deployment scenario while maintaining a consistent configuration approach.

+# Trackeep Saver Browser Extension
+
+This folder contains a WebExtension (Manifest v3) that lets you:
+
+- **Save the current page or video** as a **Trackeep bookmark**.
+- **Upload a local file** directly to Trackeep.
+- **Right‑click** any page, link, selection, image, or video and choose **“Save to Trackeep”** from the context menu.
+
+It is designed to work in **Chrome**, **Microsoft Edge**, and **Firefox** (Manifest v3 where available).
+
+---
+
+## Folder structure
+
+- `manifest.json` – WebExtension manifest (v3) with background service worker and context menu.
+- `popup.html` / `popup.js` – Popup UI and logic to save bookmarks and upload files.
+- `options.html` / `options.js` – Options page to configure API URL and auth token.
+- `background.js` – Service worker that creates and handles the context menu.
+- `icons/` – Placeholder icon files (copied from the repo favicon).
+- `README.md` – This documentation.
+
+> Note: For store publishing you will likely want custom icon PNG files. See the publishing section.
+
+---
+
+## What the extension does
+
+### Popup (toolbar icon)
+
+- Reads the **active tab’s title and URL** and lets you save it as a Trackeep bookmark.
+- Lets you add an optional **description**, **tags** (comma-separated), and mark a bookmark as **public**.
+- Lets you pick a local **file** and upload it to Trackeep with an optional description.
+
+### Right‑click context menu
+
+- Right‑click any page, link, selection, image, or video and choose **“Save to Trackeep”**.
+- The popup opens with:
+  - URL pre‑filled (link URL, image/video source, or current page URL).
+  - Title pre‑filled (tab title).
+  - Description pre‑filled with the selected text (if any).
+- Works even if you right‑click a link on another site; the popup will open with that link’s details.
+
+### Auto‑detect Trackeep domain
+
+- When you open the popup or options page on a Trackeep domain (e.g. `https://app.trackeep.example`), the extension automatically:
+  - Pre‑fills the **API base URL** to `https://app.trackeep.example/api/v1`.
+  - Falls back to `http://localhost:8080/api/v1` if nothing is set and you’re not on a Trackeep domain.
+- This reduces manual setup for most users.
+
+---
+
+## Configuration (Options page)
+
+1. **Open the extension options**
+   - After loading the extension (see below), right-click its icon → **Options**.
+   - Or click **Open Options** in the popup.
+
+2. **Set the API base URL**
+   - Usually auto‑detected if you’re on a Trackeep domain.
+   - Example for local dev:
+     - `http://localhost:8080/api/v1`
+   - Example for production:
+     - `https://your-trackeep-domain.example.com/api/v1`
+
+3. **Get your Trackeep auth token**
+   - Log into Trackeep in your browser.
+   - Open **DevTools → Application → Local Storage**.
+   - Select your Trackeep origin (e.g. `http://localhost:5173` or your production domain).
+   - Find the key `trackeep_token` and copy its **value**.
+   - Paste this value into the **Auth token** field in the options page.
+
+4. **Save settings**
+   - Click **Save settings**.
+   - The popup will now use these values to call the API.
+
+> Keep your auth token private. Treat it like a password.
+
+---
+
+## Loading the extension during development
+
+### Chrome (and Brave, Vivaldi, etc.)
+
+1. Open `chrome://extensions/`.
+2. Enable **Developer mode** (top-right toggle).
+3. Click **Load unpacked**.
+4. Select the `browser-extension` folder from this repository.
+5. The extension should appear with the name **Trackeep Saver**.
+
+### Microsoft Edge
+
+1. Open `edge://extensions/`.
+2. Enable **Developer mode**.
+3. Click **Load unpacked**.
+4. Select the `browser-extension` folder.
+
+### Firefox (Manifest v3)
+
+Firefox support for Manifest v3 is still evolving, but this extension uses only basic APIs:
+
+1. Open `about:debugging#/runtime/this-firefox`.
+2. Click **Load Temporary Add-on…**.
+3. Select the `manifest.json` file inside the `browser-extension` folder.
+4. The extension will be installed temporarily (until you restart Firefox).
+
+If you hit MV3-specific issues in Firefox, you can either:
+
+- Switch to a Firefox version with MV3 enabled, or
+- Port this to a MV2 manifest (same JS/HTML, different `manifest.json`).
+
+---
+
+## Using the extension
+
+### Popup (toolbar icon)
+
+1. Make sure you configured **API base URL** and **auth token** in the options.
+2. Navigate to any page or video (e.g. a YouTube video, article, docs page).
+3. Click the **Trackeep Saver** icon in the toolbar.
+4. In the popup:
+   - Adjust **Title**, **URL**, **Description**, and **Tags** as needed.
+   - Optionally tick **Public**.
+   - Click **Save bookmark** to create a Trackeep bookmark.
+5. To upload a file:
+   - Use the **Upload file to Trackeep** section.
+   - Pick a file, optionally add a description, then click **Upload file**.
+
+### Context menu (right‑click)
+
+1. Right‑click any page, link, selection, image, or video.
+2. Choose **“Save to Trackeep”**.
+3. The popup opens with the relevant data pre‑filled.
+4. Edit as desired and click **Save bookmark**.
+
+If anything fails, an error message from the Trackeep API is shown in the popup.
+
+---
+
+## CORS and backend configuration
+
+The backend uses a CORS middleware that primarily targets browser frontends.
+Because this is a browser extension, requests are made from an extension context and usually do **not** require the same CORS headers as a regular web page.
+
+If you run into network errors:
+
+- Make sure your Trackeep backend is reachable at the URL you configured.
+- Check the browser extension console (in `chrome://extensions` → **Inspect views** → **Service worker / popup**).
+- If needed, relax or adjust the `CORS_ALLOWED_ORIGINS` env variable on the backend to include your frontend origin for normal web use. The extension itself generally should not require changes.
+
+---
+
+## Publishing to browser stores
+
+The high-level process is similar across Chrome, Edge, and Firefox:
+
+### 1. Prepare assets
+
+- Make sure `manifest.json`, `popup.*`, `options.*`, and `background.js` are all present and working.
+- Add icon PNG files (required for store publishing):
+  - The `icons/` folder contains placeholder files copied from the repo favicon.
+  - For production, replace them with custom icons at sizes 16, 32, 48, and 128 pixels.
+  - Update `manifest.json` with an `icons` section (already present).
+
+### 2. Chrome Web Store (Chrome and most Chromium browsers)
+
+1. Go to the **Chrome Web Store Developer Dashboard**.
+2. Create a new item.
+3. Zip the **contents of `browser-extension/`** (do not zip the parent folder twice).
+4. Upload the ZIP.
+5. Fill out listing details (name, description, screenshots, categories, privacy policy).
+6. Submit for review.
+
+Once published, Chrome, Brave, and other Chromium-based browsers can install it from the store.
+
+### 3. Microsoft Edge Add-ons
+
+1. Go to the **Microsoft Edge Add-ons** developer dashboard.
+2. You can often upload the same ZIP you used for Chrome.
+3. Fill in the listing information and submit.
+
+Edge is also Chromium-based, so Manifest v3 and the `chrome.*` APIs are supported.
+
+### 4. Firefox Add-ons (AMO)
+
+1. Go to **https://addons.mozilla.org/developers/**.
+2. Create a new add-on and upload the ZIP built from `browser-extension/`.
+3. If Firefox flags MV3-specific issues, follow its guidance – usually this involves:
+   - Ensuring the manifest is valid for the current Firefox MV3 implementation.
+   - Optionally adding `browser_specific_settings` in `manifest.json` with a Firefox-specific `gecko` ID.
+
+Example snippet you may add for Firefox (Chrome will ignore this block):
+
+```json
+"browser_specific_settings": {
+  "gecko": {
+    "id": "trackeep-saver@example.com",
+    "strict_min_version": "120.0"
+  }
+}
+```
+
+Use your own ID and version constraints as recommended by Mozilla.
+
+---
+
+## How to publish to extension stores
+
+### Quick checklist before you publish
+
+- [ ] Test the extension locally in Chrome/Edge/Firefox.
+- [ ] Ensure the API URL and auth token work with your Trackeep backend.
+- [ ] Replace placeholder icons with production assets (optional; `trackeepfavi_bg.png` is already used).
+- [ ] Write a short description and prepare screenshots for the store listings.
+- [ ] Decide on a publisher name and privacy policy URL (required by most stores).
+
+### Step‑by‑step publishing
+
+#### Chrome Web Store (and Chromium browsers)
+
+1. **Prepare a ZIP**
+   - Zip the **contents of `browser-extension/`** (not the folder itself).
+   - Ensure `manifest.json`, `popup.*`, `options.*`, `background.js`, and `icons/` are included.
+
+2. **Developer Dashboard**
+   - Go to the [Chrome Web Store Developer Dashboard](https://chrome.google.com/webstore/developer/dashboard).
+   - Click **Add new item**.
+   - Upload the ZIP.
+
+3. **Listing details**
+   - **Name**: Trackeep Saver
+   - **Description**: Save pages, videos, and files to your Trackeep account.
+   - **Category**: Productivity
+   - **Screenshots**: 1280x800 or 640x400 PNGs.
+   - **Icon**: 128x128 PNG (already in `icons/icon128.png`).
+   - **Privacy policy**: Required; you can host a simple page on GitHub Pages or your site.
+
+4. **Permissions review**
+   - The manifest requests `storage`, `tabs`, `activeTab`, `contextMenus`, and `<all_urls>` host permissions.
+   - Be prepared to explain why each is needed (bookmarking, uploading files, right‑click menu).
+
+5. **Submit**
+   - Review and submit. Google will review for compliance and security.
+
+#### Microsoft Edge Add-ons
+
+1. Go to the [Microsoft Edge Add-ons Developer Dashboard](https://partner.microsoft.com/dashboard/microsoftedge).
+2. Upload the same ZIP you used for Chrome.
+3. Fill out the listing (similar to Chrome).
+4. Submit. Edge’s review is usually fast.
+
+#### Firefox Add-ons (AMO)
+
+1. Go to the [Firefox Add-on Developer Hub](https://addons.mozilla.org/developers/).
+2. Click **Submit a New Add‑on** and upload the ZIP.
+3. Firefox may ask for a `browser_specific_settings.gecko.id` in `manifest.json`. If you want a fixed ID, add:
+   ```json
+   "browser_specific_settings": {
+     "gecko": {
+       "id": "trackeep-saver@example.com",
+       "strict_min_version": "120.0"
+     }
+   }
+   ```
+   Replace `example.com` with your own domain.
+4. Provide listing details and privacy policy.
+5. Submit. Mozilla’s review focuses on privacy and security.
+
+---
+
+## What you can do next
+
+- **Test thoroughly**:
+  - Save bookmarks from different sites (articles, YouTube videos, GitHub repos).
+  - Upload various file types (PDFs, images, docs).
+  - Try the right‑click context menu on links, images, and selected text.
+- **Improve UX**:
+  - Auto‑tag YouTube videos as `video`.
+  - Add a keyboard shortcut to quick‑save the current page.
+  - Sync the auth token automatically from the Trackeep web app.
+- **Prepare for stores**:
+  - Write a concise privacy policy and host it publicly.
+  - Take clean screenshots of the popup and options page.
+  - Consider a custom icon set if you want a distinct brand look.
+- **Maintain**:
+  - Keep the extension compatible with Trackeep API changes.
+  - Update the manifest version when you release updates.
+
+For now, the extension is fully functional for bookmarking pages/videos and uploading files to Trackeep, with a convenient right‑click menu and smart domain auto‑detection.

+# Mobile App Sync Testing Guide
+
+## Overview
+This guide helps you test the bi-directional synchronization between the Trackeep mobile app and web dashboard.
+
+## Prerequisites
+
+1. **Backend Server**: Ensure your Trackeep backend is running
+2. **Web Dashboard**: Access the web dashboard at `http://localhost:3000` (or your configured URL)
+3. **Mobile App**: Run the React Native app using:
+   ```bash
+   npm start
+   npm run android  # or npm run ios
+   ```
+
+## First Launch Setup
+
+1. **Server Configuration**: On first launch, the mobile app will show the server setup screen:
+   - Enter your backend URL (e.g., `http://localhost:8080`)
+   - Enter your credentials
+   - Test connection before completing setup
+
+2. **Authentication**: After setup, you'll be redirected to login with your existing credentials
+
+## Testing Real-Time Sync
+
+### Test 1: Create Content on Mobile, Verify on Web
+
+1. **On Mobile App**:
+   - Open the Dashboard
+   - Tap the FAB (+) button
+   - Create a new task, bookmark, or note
+   - Verify it appears in the mobile dashboard
+
+2. **On Web Dashboard**:
+   - Navigate to the corresponding section (Tasks, Bookmarks, or Notes)
+   - The new item should appear within seconds (if WebSocket is connected)
+   - If not, refresh the page to see the synced item
+
+### Test 2: Create Content on Web, Verify on Mobile
+
+1. **On Web Dashboard**:
+   - Create a new task, bookmark, or note
+   - Save the item
+
+2. **On Mobile App**:
+   - The item should appear automatically if real-time sync is working
+   - Pull to refresh on the dashboard to force sync
+   - Check the specific section to verify the item appears
+
+### Test 3: Offline Mode Testing
+
+1. **Enable Offline Mode**:
+   - Turn off internet connection on your mobile device
+   - The app should show "🔴 Offline" status
+
+2. **Create Content Offline**:
+   - Create several tasks, bookmarks, or notes
+   - Notice the pending changes counter increases
+
+3. **Restore Connection**:
+   - Turn internet back on
+   - App should show "🟢 Connected" and auto-sync
+   - Verify items appear on web dashboard
+
+### Test 4: Conflict Resolution
+
+1. **Simulate Conflict**:
+   - Create the same item on both mobile and web while offline
+   - Bring both online simultaneously
+   - Verify how conflicts are resolved (last write wins or merge)
+
+## Key Features to Test
+
+### Real-Time Updates
+- ✅ WebSocket connection status
+- ✅ Instant updates across devices
+- ✅ Connection recovery after disconnection
+
+### Offline Support
+- ✅ Offline data persistence
+- ✅ Pending changes tracking
+- ✅ Automatic sync when online
+- ✅ Manual sync button
+
+### Data Integrity
+- ✅ All data types sync correctly (tasks, bookmarks, notes)
+- ✅ Timestamps preserved
+- ✅ User associations maintained
+- ✅ Tags and metadata sync
+
+## Troubleshooting
+
+### Common Issues
+
+1. **WebSocket Connection Failed**:
+   - Check if backend WebSocket endpoint is accessible
+   - Verify firewall settings
+   - Check browser console for WebSocket errors
+
+2. **Sync Not Working**:
+   - Verify server URL in mobile app settings
+   - Check authentication tokens
+   - Review backend logs for sync errors
+
+3. **Offline Mode Not Detected**:
+   - Check network permissions on mobile device
+   - Verify NetInfo plugin is working
+   - Test with airplane mode
+
+### Debug Tools
+
+1. **Mobile App Debugging**:
+   ```bash
+   # Enable debug mode
+   npx react-native log-android
+   npx react-native log-ios
+   ```
+
+2. **Backend Logs**:
+   - Monitor sync endpoint logs
+   - Check WebSocket connection logs
+   - Review database transaction logs
+
+3. **Browser Console**:
+   - Monitor WebSocket connections
+   - Check for real-time update events
+   - Verify API responses
+
+## Performance Testing
+
+### Test Scenarios
+
+1. **Large Dataset Sync**:
+   - Create 100+ items on one device
+   - Measure sync time to other device
+   - Verify no data loss
+
+2. **Concurrent Updates**:
+   - Multiple users updating same data
+   - Test conflict resolution
+   - Verify data consistency
+
+3. **Network Conditions**:
+   - Test on slow networks (2G/3G)
+   - Test with intermittent connectivity
+   - Verify sync resilience
+
+## Expected Results
+
+### Successful Sync Indicators
+
+1. **Mobile App**:
+   - Status shows "🟢 Connected"
+   - Last sync time updates
+   - No pending changes counter
+   - Real-time updates received
+
+2. **Web Dashboard**:
+   - New items appear without refresh
+   - WebSocket connection established
+   - No sync errors in console
+
+### Performance Benchmarks
+
+- **Small items** (< 1KB): Should sync within 1-2 seconds
+- **Large items** (> 100KB): Should sync within 5-10 seconds
+- **Batch sync** (50+ items): Should complete within 30 seconds
+
+## Automated Testing
+
+For comprehensive testing, consider implementing:
+
+1. **Unit Tests**:
+   - Sync logic validation
+   - Offline queue management
+   - Conflict resolution
+
+2. **Integration Tests**:
+   - End-to-end sync workflows
+   - WebSocket connection testing
+   - API integration validation
+
+3. **E2E Tests**:
+   - Multi-device sync scenarios
+   - Offline/online transitions
+   - User interaction flows
+
+## Reporting Issues
+
+When reporting sync issues, include:
+
+1. Device information (OS, version)
+2. Network conditions
+3. Steps to reproduce
+4. Screenshots of error messages
+5. Backend logs (if available)
+6. Browser console errors
+
+## Success Criteria
+
+The sync implementation is considered successful when:
+
+- ✅ All data types sync bi-directionally
+- ✅ Real-time updates work within 5 seconds
+- ✅ Offline mode functions correctly
+- ✅ No data loss during sync
+- ✅ Conflicts are handled gracefully
+- ✅ Performance meets benchmarks
+- ✅ Error recovery works reliably

+# OAuth Service Configuration Changes
+
+## Summary of Changes
+
+### 1. CORS Configuration Updated
+- **Before**: Restricted to specific origins (`http://localhost:5173,http://localhost:8080`)
+- **After**: Allows all origins (`*`) for maximum flexibility
+- **Implementation**: Updated CORS middleware to handle wildcard origins properly
+
+### 2. Dynamic Client URL Detection
+- **Before**: Hardcoded default client URL (`http://localhost:5173`)
+- **After**: Dynamically determines client URL from:
+  - Query parameter `redirect_uri` (highest priority)
+  - Request `Origin` header
+  - Request `Referer` header
+  - Fallback to `DEFAULT_CLIENT_URL` environment variable
+- **Implementation**: Enhanced `initiateGitHubOAuth` function with URL parsing logic
+
+### 3. Service Domain Configuration
+- **Added**: New `SERVICE_DOMAIN` environment variable
+- **Purpose**: Identifies the OAuth service domain in logs and webhook responses
+- **Current Value**: `https://oauth.tdvorak.dev`
+
+### 4. Enhanced Webhook Handling
+- **Before**: Basic webhook processing with minimal logging
+- **After**: 
+  - Proper webhook secret configuration check
+  - Enhanced logging with service domain identification
+  - Detailed event type handling with better payload logging
+  - Response includes service domain information
+
+### 5. Environment Files Updated
+- **`.env`**: Updated with new configuration values
+- **`.env.example`**: Updated to reflect the new structure for other deployments
+
+## Key Benefits
+
+1. **Multi-domain Support**: Service can now handle requests from any domain
+2. **Dynamic Client Detection**: Automatically redirects users back to their originating domain
+3. **Better Debugging**: Enhanced logging makes troubleshooting easier
+4. **Production Ready**: Configuration is more flexible for different deployment scenarios
+
+## Security Considerations
+
+- While CORS is set to allow all origins, the OAuth flow itself remains secure
+- State parameter validation prevents CSRF attacks
+- JWT tokens are still properly validated
+- Webhook signature validation is in place (though secret needs to be configured)
+
+## Usage
+
+The service will now:
+1. Accept OAuth requests from any domain
+2. Automatically detect the client's origin for proper redirects
+3. Handle webhooks with better logging and domain identification
+4. Work seamlessly with the user's domain (`tdvorak.dev`) and any other domains

+# Centralized OAuth Service
+
+This is a **standalone OAuth service** that handles GitHub authentication and email verification for all users. Users never need to set up their own OAuth applications - everything is centralized.
+
+## 🎯 **How It Works**
+
+### **For Users:**
+1. **GitHub OAuth**: Click "Connect GitHub" → GitHub authorization → Automatic login with GitHub profile
+2. **Email Verification**: Enter email → Receive verification code → Verify email for 2FA
+
+### **For Developers:**
+1. **Zero setup** - No OAuth app creation needed
+2. **Simple integration** - Just redirect to our service
+3. **Secure authentication** - We handle all the complexity
+4. **User management** - Centralized user database
+
+## 🚀 **Quick Start**
+
+### **1. Setup the OAuth Service**
+
+```bash
+# Navigate to the OAuth service
+cd oauth-service
+
+# Run the setup script
+./setup.sh
+
+# Edit the .env file with your GitHub OAuth credentials
+nano .env
+
+# Start the service
+go run main.go
+```
+
+### **2. GitHub OAuth App Setup (One Time)**
+
+1. Go to GitHub Settings → Developer settings → OAuth Apps
+2. Create a new OAuth app with:
+   - **Application name**: Trackeep OAuth Service
+   - **Homepage URL**: `http://localhost:9090`
+   - **Authorization callback URL**: `http://localhost:9090/auth/github/callback`
+3. Copy the Client ID and Client Secret to `.env`
+
+### **3. Email Verification Setup (One Time)**
+
+1. Configure smtp.purelymail.com for sending verification emails:
+   - **SMTP Host**: `smtp.purelymail.com`
+   - **SMTP Port**: `587`
+   - **Username**: Your purelymail SMTP username
+   - **Password**: Your purelymail SMTP password
+2. Add SMTP credentials to `.env` file
+3. The service will send 6-digit verification codes for 2FA
+
+### **4. Integration in Your App**
+
+```javascript
+// Redirect to GitHub OAuth
+const connectGitHub = () => {
+  window.location.href = 'http://localhost:9090/auth/github?redirect_uri=' + 
+    encodeURIComponent(window.location.origin);
+};
+
+// Send email verification code
+const sendEmailVerification = (email) => {
+  fetch('http://localhost:9090/api/v1/email/send', {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify({ email })
+  }).then(response => response.json())
+    .then(data => {
+      if (data.demo_code) {
+        console.log('Demo verification code:', data.demo_code);
+      }
+    });
+};
+
+// Verify email code
+const verifyEmailCode = (email, code) => {
+  fetch('http://localhost:9090/api/v1/email/verify', {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify({ email, code })
+  }).then(response => response.json())
+    .then(data => {
+      if (data.verified) {
+        console.log('Email verified successfully!');
+      }
+    });
+};
+
+// Handle callback (works for both GitHub and Email)
+const handleCallback = () => {
+  const urlParams = new URLSearchParams(window.location.search);
+  const token = urlParams.get('token');
+  const username = urlParams.get('user');
+  
+  if (token) {
+    localStorage.setItem('token', token);
+    localStorage.setItem('username', username);
+    // Redirect to dashboard
+    window.location.href = '/app';
+  }
+};
+```

+# Trackeep Integration Guide
+
+## Architecture Overview
+
+This OAuth service is designed **only for authentication**. Trackeep instances (user-hosted) handle all GitHub data tracking directly.
+
+## How It Works
+
+### 1. User Authentication Flow
+1. User clicks "Login with GitHub" in Trackeep
+2. Trackeep redirects to: `https://oauth.tdvorak.dev/auth/github?redirect_uri=https://user-trackeep-instance.com`
+3. OAuth service handles GitHub authentication
+4. OAuth service redirects back: `https://user-trackeep-instance.com/auth/callback?token=JWT&user=username`
+
+### 2. What Trackeep Receives
+The JWT token contains:
+```json
+{
+  "user_id": 123,
+  "github_id": 456789,
+  "username": "johndoe",
+  "email": "john@example.com",
+  "access_token": "gho_16C7e42F292c6912E7710c838347Ae178B4a",
+  "token_type": "bearer",
+  "expires_at": 1738123456,
+  "exp": 1738123456,
+  "iat": 1737518656
+}
+```
+
+### 3. Trackeep GitHub API Access
+Trackeep instances can now make GitHub API calls using the user's `access_token`:
+
+```javascript
+// Example: Get user repositories
+const response = await fetch('https://api.github.com/user/repos', {
+  headers: {
+    'Authorization': `Bearer ${accessToken}`,
+    'Accept': 'application/vnd.github.v3+json'
+  }
+});
+
+// Example: Get commits for a repo
+const commits = await fetch(`https://api.github.com/repos/${owner}/${repo}/commits`, {
+  headers: {
+    'Authorization': `Bearer ${accessToken}`,
+    'Accept': 'application/vnd.github.v3+json'
+  }
+});
+```
+
+## Trackeep Implementation Guide
+
+### 1. OAuth Login Button
+```html
+<a href="https://oauth.tdvorak.dev/auth/github?redirect_uri=https://your-trackeep-instance.com">
+  Login with GitHub
+</a>
+```
+
+### 2. Handle OAuth Callback
+```javascript
+// In your /auth/callback route
+async function handleOAuthCallback(req, res) {
+  const { token, user: username } = req.query;
+  
+  // Decode and verify JWT
+  const jwtPayload = decodeJWT(token);
+  
+  // Store user session
+  req.session.user = {
+    id: jwtPayload.user_id,
+    username: jwtPayload.username,
+    email: jwtPayload.email,
+    githubAccessToken: jwtPayload.access_token,
+    tokenType: jwtPayload.token_type,
+    expiresAt: jwtPayload.expires_at
+  };
+  
+  // Redirect to dashboard
+  res.redirect('/dashboard');
+}
+```
+
+### 3. GitHub API Helper
+```javascript
+class GitHubAPI {
+  constructor(accessToken) {
+    this.accessToken = accessToken;
+  }
+  
+  async makeRequest(url) {
+    const response = await fetch(url, {
+      headers: {

+
+### 4. Track Data Collection
+```javascript
+// Example: Track repository activity
+async function trackRepositoryActivity(user, repoFullName) {
+  const [owner, repo] = repoFullName.split('/');
+  const github = new GitHubAPI(user.githubAccessToken);
+  
+  // Get commits
+  const commits = await github.getRepoCommits(owner, repo);
+  
+  // Get pull requests
+  const pulls = await github.getRepoPulls(owner, repo);
+  
+  // Store in your local database
+  await storeActivityData({
+    userId: user.id,
+    repo: repoFullName,
+    commits: commits.length,
+    pullRequests: pulls.length,
+    lastActivity: new Date()
+  });
+}
+```
+
+## Security Considerations
+
+### 1. Token Storage
+- Store GitHub access tokens securely (encrypted at rest)
+- Never expose tokens in client-side JavaScript
+- Use secure, HTTP-only cookies for session management
+
+### 2. Token Expiration
+- Monitor `expires_at` field in JWT
+- Refresh tokens before expiration if needed
+- Handle token expiry gracefully
+
+### 3. Rate Limiting
+- GitHub API has rate limits (5,000 requests/hour for authenticated users)
+- Implement caching to reduce API calls
+- Handle rate limit responses (HTTP 429)
+
+## Available GitHub Scopes
+
+The OAuth service requests these scopes:
+- `user:email` - Read user email addresses
+- `read:user` - Read user profile data  
+- `repo` - Access to repositories (full control)
+
+This allows Trackeep instances to:
+- Read repository data
+- Access commit history
+- Monitor pull requests
+- Track branch activity
+
+## API Endpoints
+
+### OAuth Service
+- `GET /auth/github` - Initiate OAuth flow
+- `GET /auth/github/callback` - Handle GitHub callback
+- `GET /api/v1/user/me` - Get current user info
+
+### GitHub API (via access token)
+- `GET /user/repos` - User repositories
+- `GET /repos/{owner}/{repo}/commits` - Repository commits
+- `GET /repos/{owner}/{repo}/pulls` - Pull requests
+- `GET /repos/{owner}/{repo}/branches` - Branches
+- And all other GitHub API endpoints
+
+## Benefits of This Architecture
+
+1. **Separation of Concerns** - OAuth service only handles authentication
+2. **User Privacy** - GitHub data stays in user's Trackeep instance
+3. **Scalability** - Each user instance handles its own GitHub API calls
+4. **Security** - No centralized GitHub data storage
+5. **Flexibility** - Trackeep can implement custom tracking logic
+
+## Example Implementation
+
+See the `examples/` directory for complete implementation examples in different frameworks.

-Trackeep is an open-source, self-hosted platform designed to help you store, organize, and track all your digital content—from bookmarks and documents to learning progress, tasks, media, and files. Think of it as a hybrid of Papr, Notion, Pocket, and Todo apps, built for developers, learners, and knowledge workers who want full control over their data.
+## Introduction
 
-With Trackeep, everything you save is centralized, searchable, and easy to manage, while remaining self-hosted so you maintain full privacy and ownership.
+I built Trackeep because I was tired of juggling a dozen different apps for my digital life. You know how it is – bookmarks in one place, tasks in another, random notes scattered everywhere, and that great article you meant to read somewhere in your browser history.
 
-## Core Features
+So I decided to build my own solution. Trackeep is basically the app I wish I had – one place to store, organize, and track everything that matters to me. It's open-source and self-hosted because I believe your data should belong to you, not some corporation.
 
-### 1. Bookmarks & Link Management
+It's like if Papra, Notion, Pocket and a todo app had a baby. Built by one person (with AI's help), for anyone who's tired of their digital life being a mess.
-- Save and categorize links, articles, videos, and web resources
-- Tag and search efficiently to retrieve content quickly
-- Import/export from browser or other tools
 
-### 2. Learning & Progress Tracking
+### My Design Inspiration
-- Track courses, tutorials, and personal learning paths
-- Record progress on skills or tasks over time
-- Integrate video resources like YouTube for reference
 
-### 3. Task & To-Do Lists
+I've always been a huge fan of **Papra** – their clean, minimalistic approach just makes sense. Everything feels intentional and puts your content first.
-- Plan future tasks, create checklists, and mark completed items
-- Organize tasks by priority, category, or tags
 
-### 4. Media & File Storage
+So yeah, Trackeep borrows heavily from that design philosophy. But I wrote every line of code from scratch – this isn't some copy-paste job. I took that beautiful simplicity and tried to expand it into more of a productivity and knowledge management tool.
-- Upload, store, and manage documents, presentations, images, and videos
-- Quick download and optional preview (for supported formats)
 
-### 5. Notes & Annotations
+### The AI-Assisted Journey
-- Add personal notes to saved links, files, or tasks
-- Keep all related content in one place
 
-### 6. Tagging & Organization
+This project was built with **Windsurf SWE 1.5**.
-- Assign multiple tags or categories for efficient sorting
-- Use smart rules for automated tagging
 
-### 7. Privacy & Self-Hosting
+Look, I'll be honest – I'm not the best coder out there. But I really wanted to build something that solves real problems, and I think passion matters more than being perfect. Windsurf helped me figure out the hard stuff, learn new technologies, and actually build something I'm proud of.
-- Fully self-hosted; no third-party servers required
-- Data is yours—encrypted and controlled
 
-### 8. Optional Integrations
+As a solo dev, having an AI pair programmer made this whole thing possible. Go backend, SolidJS frontend, React Native app – stuff I probably couldn't have tackled alone. It's pretty cool what you can create when humans and AI work together, even when you're still learning.
-- Browser extensions for faster saving

-- API endpoints for custom scripts and automation
+With Trackeep, everything you save is centralized, searchable, and easy to manage, while remaining self-hosted so you maintain full privacy and ownership – just as it should be.
+
+## Project Status
+
+Trackeep is my labor of love – constantly evolving with core functionalities that I use every day. As a solo developer, I'm building this in the open, adding features based on real needs and feedback from fellow digital wanderers. The platform includes multiple services working together to create the productivity hub I've always wanted.
+
+Every feature you see is something I personally needed and use. Your feedback, bug reports, and feature ideas aren't just welcome – they're what help shape this tool into something that can help others organize their digital lives too.
+
+## Features
+
+### Core Functionality

+- **Learning & Progress Tracking**: Track courses, tutorials, and personal learning paths
+- **Task & To-Do Lists**: Plan future tasks, create checklists, and mark completed items
+- **Media & File Storage**: Upload, store, and manage documents, presentations, images,... (just like Papra)
+- **Notes & Annotations**: Add personal notes to saved links, files, or tasks
+- **Tagging & Organization**: Assign multiple tags or categories for efficient sorting
+
+### Advanced Features

+- **Dark Mode**: Beautiful dark theme for low-light environments
+- **Responsive Design**: Works seamlessly on desktop, tablet, and mobile devices
+
+### Privacy & Self-Hosting
+- **Fully Self-Hosted**: No third-party servers required – everything runs on your own infrastructure
+- **Data Ownership**: Your data remains yours – encrypted, controlled, and never leaves your systems
+- **Open Source**: Transparent codebase you can audit, modify, and trust
+- **API Access**: Build custom applications on top of Trackeep
+- **AI Control**: Full control over which AI services (if any) you want to use
+
+### AI Services (Optional & Configurable)
+
+Trackeep includes AI features, but you're in complete control:
+
+**Currently Integrated:**
+- **LongCat AI** – For content recommendations, smart tagging, and text extraction
+- **DeepSeek** – Advanced reasoning and content analysis capabilities
+- **Mistral AI** – European AI with strong privacy focus
+- **Grok (xAI)** – Real-time knowledge and witty responses
+- **Ollama** – Self-hosted local AI models (run completely offline)
+- **OpenAI Compatible** – Can be configured with any OpenAI-compatible API endpoint
+
+**Your Options:**
+- ✅ **Use all AI features** – Full experience with intelligent automation
+- ✅ **Use specific AI services** – Enable only the features you want
+- ✅ **Use only local AI** – Run completely offline with Ollama
+- ✅ **Disable all AI** – Run Trackeep completely without any AI integration
+- ✅ **Replace with your own** – Configure custom AI endpoints or self-hosted models
+
+**A Note on AI Services & Privacy:**
+
+Look, I want to be completely transparent with you. **DeepSeek and LongCat AI are Chinese companies**, and I totally get if that raises some concerns for you. Data privacy is serious business.
+
+But here's my honest take: with the pricing they offer (especially DeepSeek's incredibly cheap API), I personally feel more comfortable giving my data to them than to ChatGPT at their prices. Plus, you're in complete control – you can disable any service you don't want, or stick to European options like Mistral, or even run everything locally with Ollama.
+
+The beauty of Trackeep is that **you decide**. No hidden data collection, no forced AI usage – just transparent options that you control.
+
+**Privacy First:**
+- All AI processing happens through your configured endpoints
+- No data sent to third-party services without your explicit configuration
+- AI features can be completely disabled for maximum privacy
+- Full transparency about what data is sent to AI services
+- Local AI option with Ollama for complete offline privacy
+
+**Example Configurations:**
+```bash
+# Disable all AI
+DISABLE_AI=true
+
+# Use only European AI (Mistral)
+MISTRAL_API_KEY=your-key
+DISABLE_LONGCAT=true
+DISABLE_DEEPSEEK=true
+DISABLE_GROK=true
+
+# Use only local AI (Ollama)
+OLLAMA_BASE_URL=http://localhost:11434
+DISABLE_ALL_CLOUD_AI=true
+
+# Budget-friendly setup (DeepSeek + LongCat)
+DEEPSEEK_API_KEY=your-key
