What your browser tells websites

Every site you visit sees your IP address and the headers your browser sends, and its scripts can read your screen, time zone, language and hardware. Here's all of it for this browser. Nothing on this page is stored.

Where you are

Two ways a site can place you. Your IP address gives it away to every site, roughly. Your device knows far more precisely, but only tells a site if you allow it.

Your fingerprint

The details further down, hashed together. It stays the same in a private window and after you clear cookies, which is how sites recognise you without any. Reload: if the ID changes, your browser is scrambling it to protect you.

Your browser

The user agent is the name tag sent with every request. Browsers now freeze parts of it (Windows 11 still says "Windows NT 10.0"), so your system above comes from client hints where offered.
