Privacy policy

We collect as little as possible. There are no accounts and no forms.

Game progress, streaks, statistics and settings are stored in your browser's local storage. They never leave your device and we cannot see them. Clearing your browser data removes them.

We use a privacy-friendly analytics tool to count visits and see which puzzles are played. It does not use cookies for tracking and does not build profiles across sites. Data such as the page visited, referrer, device type and country are processed in aggregate.

If advertising is added in the future, this page will be updated to explain which partners are involved and how to opt out.
