Privacy

What we count. Which groups, stories and ads are opened, how fast the map loads, and whether you are on a phone or a computer.

What we don’t. Nothing is stored on your device: no cookies and no saved ID, so each visit counts as a new, anonymous visitor. We never collect names, email addresses or your exact location.

Where it goes. The counts go to Mixpanel’s servers in the EU and are used only to improve this site. Mixpanel works out a rough country and city from the connection; nothing more precise.
