We don't track you. Progress is stored in your browser's localStorage under keys prefixed with ccp.. Clearing site data resets your progress.

If you sign in (optional), your progress is also synced to our database so it follows you across devices. We store only your email, name, and progress data.

We don't sell data. We don't run third-party trackers. Server logs (HTTP method, path, status, IP) are retained for 14 days for debugging.
