🔄 Update System

The PWA includes an intelligent update system that ensures users always get the latest version:

Automatic Updates

• Version-based Caching: Each deployment uses a unique cache name based on version
• Network-First Strategy: Always tries to fetch fresh content from the server
• Update Detection: Automatically detects when new versions are available
• Periodic Checks: Checks for updates every hour in the background
• User Notifications: Shows update notifications when new versions are ready

Manual Update Check

• Settings Page: "Check for Updates" button in the settings
• Immediate Refresh: Users can apply updates immediately
• Status Feedback: Clear indication of update status and progress

Deployment Process

1. Update Version: Run node update-version.js v1.0.5 (replace with new version)
2. Test Locally: Verify changes work as expected
3. Commit & Push: Push to GitHub repository
4. Auto-Deploy: GitHub Pages automatically deploys the update
5. User Updates: Users see update notifications on next visit

Version Management

• Service Worker: Cache version in service-worker.js
• Manifest: App version in manifest.json
• Synchronized: Both files updated together via script
• Semantic Versioning: Follows vX.Y.Z format (e.g., v1.0.5)

All your data is encrypted using AES-256-GCM encryption before being stored locally or synced to cloud:

// Your data is automatically encrypted
const notes = await storage.loadEncrypted('notes');
await storage.saveEncrypted('notes', updatedNotes);

// Optional password protection for extra security
await storage.saveEncrypted('sensitive-note', data, 'your-password');

// Cloud sync with encryption
await cloudManager.syncToCloud(); // Automatically encrypts before sync

Privacy First

• Local Storage: All data stays on your device
• No Tracking: No analytics or user tracking
• Offline Capable: Works completely offline
• Export Control: You own and control your data

Backup & Restore
