Settings

Manage your study progress and offline access. Everything you track — known concepts, quiz scores, flashcard schedules, notes and your streak — is stored locally in this browser. Nothing is uploaded. Use the backup tools below to move progress between browsers or devices.

Backup & restore

Progress is saved only on this device and browser. Export a snapshot to keep a copy or carry it elsewhere; import it on another browser to continue where you left off.

Offline access

This app works offline once loaded. Pages, styles and study data are cached by a service worker, so you can keep studying without a connection. Visit the pages you want available offline while online at least once.

Danger zone

Resetting clears all progress stored in this browser — known concepts, quiz scores, flashcard schedules, notes and your streak. This cannot be undone. Export a backup first if you want to keep it.
