To guarantee database safety, authentication credentials and tokens are encrypted locally inside IndexedDB using the browser's native Web Crypto API.
The app generates a non-exportable AES-GCM key bound directly to the browser's secure context. Access control is verified via a custom PBKDF2 PIN layout and WebAuthn credentials for secure biometric login (TouchID/FaceID).
All client interactions write instantly to the local IndexedDB database, ensuring a true offline-first performance experience.
Modifications are synchronized to the Supabase backend in the background using a delta-sync mechanism. Operations are protected against connection drops with soft delete flags and standard client-side conflict resolution panels.
