Visit statistics

Visits are counted with the website's own statistics, which use no cookies and store nothing in your browser. Each visit is counted with an anonymous identifier made from the request, which changes every day, so visits on different days can't be linked, and the IP address is never stored. The approximate location (city and country) comes from the connection. The only thing the page checks in your browser is an opt-out setting that exists only in the site owner's own browser, so their visits aren't counted.
