Privacy Policy
Last updated: 21 October 2026
Summary
The games run in your browser. We do not ask you to create an account and we do not receive your scores, profile or anything you do in a game. When advertising is enabled, third-party vendors including Google may use cookies and similar technologies to show ads.
Information stored on your device
- Local profile. Your display name, scores, stars, achievements, streaks and level are saved in your browser local storage so they are still there next time. They are not sent to our servers.
- Game settings. Difficulty, current level, the sound on/off choice and your cookie notice choice are stored the same way.
- Profile export code. The export code on the profile page is generated in your browser. It contains your profile data. Anyone who has the code can import it, so share it only with yourself.
You can remove all of this at any time by clearing site data for this site in your browser settings or with the reset button on the profile page.
Friend challenge links
If you use the challenge a friend feature, a link is created that contains a puzzle seed, the score to beat and your display name as query parameters. Anyone with the link can see those values. Do not use a display name you do not want to share.
