Analytics

This site uses Google Analytics to count visits and see how the site is used. Google Analytics sets cookies in your browser (named _ga and _ga_ followed by an ID) to tell one visit from the next. Google receives your IP address and details of your browser and device, such as its type, language and screen size. There is no advertising.

You can turn analytics off: on your first visit, with the banner at the bottom of the page (Settings, untick Analytics, Save), and at any time with Privacy settings at the bottom of every page. Turning it off stops the counting and removes the Google Analytics cookies. Your choice is kept in your browser.

Signing in

To sign in you give your email address, and we send it a sign-in link. Opening the link sets a cookie, pr_session, that keeps you signed in for 30 days; signing out removes it. The link and the cookie are signed, not stored.

Your saved games

Your saved games are kept on our servers under a code made from your email address, not the address itself, so that you can carry on from any browser. Nothing else about you is kept.
