Page-view counts
Our server counts page views without cookies. For each page request it records the page address, country, region and city, the network operator's name, device type, browser and its identification string (user agent), referring site and a visitor code. The visitor code is a one-way hash of your IP address and browser that changes every day, so it cannot identify you or follow you across days. IP addresses themselves are not stored. The site is hosted on Cloudflare, which processes requests under its own privacy policy.
Advertising
The site does not show ads today. If we add Google AdSense later, Google and its partners may use cookies to show ads based on your visits to this and other sites. This page will be updated before that happens, and you will be able to opt out of personalised ads at Google Ads Settings or aboutads.info. Visitors in the European Economic Area and the UK will be asked for consent first.
