How Offline Mode Works
Industry-standard web technologies power a true offline-first experience.
Local Database
Evidence photos, GPS coordinates, notes, and voice recordings store directly on your device in a persistent local database. Data survives app restarts and network loss.
Background Sync
A service worker monitors your connection in the background. The moment you reconnect, it automatically syncs all offline-captured evidence to the cloud β no manual action needed.
Push Infrastructure
Web Push Protocol delivers notifications to your device even when the app is not open. Case updates, settlement alerts, and deadline warnings arrive instantly.
