You don't sign up, log in or give us your name or email to play.
What stays on your device
Your match in progress and your settings are saved in your browser's local storage on your device, so a refresh doesn't lose your game. They're never sent to us. You can remove them at any time by starting a new match or clearing your browser's site data.
Analytics
We use Vercel Web Analytics to count visits, the pages viewed, where visitors came from (for example a search engine) and how many games are played. It uses no cookies and doesn't identify you or follow you across other sites.
Cookies
OneGammon doesn't set cookies.
Changes
If this policy changes, for example when online play with friends arrives, we'll update this page and its date.
