Privacy Policy

Nothing personal. There are no accounts, no sign-ups and no forms that ask for your details.

Every deck is generated in your browser. The settings you choose and any custom pairs you type are never sent to a server, and the PDF is rendered locally on your own device.

The online game saves your best move count in your browser's local storage so you can beat it later. Clearing your browser data removes it. It never leaves your device.

This site displays ads through Google AdSense. Google may use cookies and similar technologies to serve relevant ads based on your visit here and elsewhere. You can manage or opt out of personalized advertising through Google's Ad Settings.

Because no personal information is collected from anyone, the site is safe for classroom use with children.

If this policy ever changes, the updated version will be posted on this page.
