Does it work offline?▾

Yes. Records are stored on your device and all core features work without a network connection.

What happens to my data if I cancel?▾

Local data and free features keep working. Resubscribing restarts sync.

Can I delete my account completely?▾

Yes — from the Account screen in the app. Server-side data is fully erased.
