Privacy policy

Data stored on your device

Your game progress, settings, statistics and daily streak are saved in your browser's local storage. This data never leaves your device, and you can delete it at any time by clearing your browser's site data.

Analytics

We use Google Analytics for Firebase to understand, in aggregate, how the site is used: for example, which puzzle sizes are popular and how many puzzles are completed. It collects standard usage data such as pages viewed, approximate location (country or city), device type and gameplay events. Google may use cookies or similar identifiers for this. We do not collect names, email addresses or other directly identifying information, and we do not sell data. You can opt out with your browser's tracking protection or the Google Analytics opt-out add-on.

Accounts

There are no accounts. We don't ask for, or store, personal information.

Children

The site is suitable for all ages and does not knowingly collect personal information from children.
