Privacy policy

Daily Brain Puzzles (this website and the Daily Brain Puzzles app) is built to need as little data as possible.

No accounts, no personal data

You don't sign up and we don't ask for your name, email or any other personal information.

Your progress stays on your device

Solved puzzles, your streak and settings (sound, reminder time) are stored only in your browser or on your phone. Clearing site data or uninstalling the app removes them.

Anonymous play counts

When a puzzle is opened, solved, revealed or a hint is used, an anonymous event with only the puzzle id and the event name is sent to our server so we can see which puzzles people enjoy. It contains no identifier for you or your device. We use no cookies, no advertising and no third-party analytics.

Notifications

The app can remind you about the daily challenge with a notification scheduled on your phone. Nothing is sent to us, and you can turn it off at any time in the app's settings.
