Data & sync

Permanent and account-wide

This clears learning records from the signed-in account and this device, including saved words, notes, submitted lesson writing, review history, progress and captures. It cannot be undone. Your sign-in, credentials and bundled curriculum are not changed.

The account reset also advances a protected generation, so an older offline device cannot restore the deleted records when it reconnects.

Sign in to clear both cloud and local records.

• Signing in, opening the app, reconnecting and returning to the app all start sync automatically.
• Records are merged individually. Records found on only one device are kept, and lesson progress can only move forwards: the higher valid percentage wins, with completed winning a tie.
• Writing is saved locally while you type. Only an explicitly submitted lesson checkpoint is uploaded.
• Offline changes stay in a durable queue and resume automatically after reconnecting.
• Only your own account rows are readable, enforced by the database.
