Privacy

Draft for the preview build, last updated October 21, 2026. It describes what this version of the site actually does.

What we store

Your game progress (which games you finished, your result, and any unfinished game) is stored in your browser's IndexedDB on your device. It isn't sent to our servers. You can delete it in Settings or by clearing site data.

What we don't collect

No account, no email, no product analytics, no advertising identifiers, no location, no contacts. There are no ads or third-party tracking scripts.

Challenge links

A challenge link contains the game and your result (for example, "solved on the second try"). It doesn't include your name or any personal information. Anyone you send it to can see that result.

Server logs

Our hosting provider may keep standard request logs (such as IP address and browser type) for security and reliability. We plan to keep operational logs for no more than 30 days.

Changes

Before we add accounts or analytics, we'll update this page and ask for consent where required.
