The app (Durgical)
The app stores in your browser (local storage, not advertising cookies):
- your language and app preferences (layers, colours, views);
- your session, if you signed in (so it doesn't ask for your email every time);
- a copy of your notes, so they work offline and sync later;
- your quiz and review progress.
You can clear it in your browser settings. If you clear storage you'll need to sign in again; your synced notes stay in your account.
