Notes

• The app uses Firebase Firestore for cloud storage
• User authentication required (Apple or Google Sign In)
• Notes sync in real-time across devices
• Subscription status is stored locally (for MVP)
• AI queries are limited to 10 per day for free users
• Free users can create up to 5 notes
• Subscription unlocks all limitations

Database Recommendation

Firebase Firestore is recommended and implemented because:

• ✅ Built-in authentication (Apple & Google Sign In)
• ✅ Real-time synchronization
• ✅ Offline support
• ✅ Scalable NoSQL database
• ✅ Free tier available
• ✅ Excellent iOS/Swift support
• ✅ Easy to set up and maintain

Alternative options considered:

• Supabase: Open-source alternative, PostgreSQL-based
• AWS Amplify: More complex setup, better for enterprise
• CloudKit: Apple-only, limited to Apple Sign In
