Keep studying on this device or sign in to sync
Guest mode keeps your progress only on this device. Sign in with Google to sync across devices, or save a backup file first.
Checking sync status
Looking for the cloud session
This will switch between guest mode and signed-in sync once the Cloudflare backend is available.
Your Google account is already verified. Pick the public name required for future leaderboards, then finish sign up. It cannot be changed later.
Guest-only backup
Use these only if you are studying without signing in. Signed-in accounts already sync automatically.
This clears your study progress, streak, and achievements on this device.
Cloud sync will store only the data required for progress, streaks, heatmap, daily stats, and a fixed display name.
