How we count visits

We use Cloudflare Web Analytics to see how many people visit and which pages they read. It sets no cookies, does not follow you to other sites, and does not build a profile of you. It records things like the page address, the country, the kind of browser, and how fast the page loaded. Cloudflare's own Web Analytics page explains more.

Our site search runs in your browser too. What you search for is not sent to us.
