Privacy policy
No account is required. Calculation inputs and game answers are processed in your browser; we do not provide a feature that saves them on our server. Language and theme preferences are stored in local storage. The Korean daily challenge stores up to 14 days of best scores. You can clear these using your browser’s site-data settings.
Shared links contain experiment conditions or a game seed. Shared text can include your self-reported score, accuracy and response time. Check before sharing. If you email us, we use voluntarily provided names, email addresses and message details to investigate and reply, deleting them when no longer needed and retaining only the minimum where necessary.

Content pages contain Google AdSense code. Google and third-party advertising providers may use cookies and similar technology for ads, measurement and personalization based on visits to this and other sites. They may process IP addresses, device/browser information and ad interactions under their policies and your settings. We do not separately transmit calculation inputs to advertisers. You can change ad personalization or block/delete cookies; disabling personalization does not remove all ads.
