Open any website and it immediately learns a fair amount about you, all from normal browser behaviour. None of it includes your name on its own, but together it paints a detailed picture.

- Your screen size, language, and time zone.
- The page that referred you, and how you move through the site.
- Enough combined detail to fingerprint and recognise you.
