What sites see about you
This page shows the data your browser just sent us, exactly the way any site receives it. Nothing is stored.
Every request your browser makes carries this bundle by default. Site owners see it in their logs without asking, and trackers stitch it together across pages.
The referrer line is the one this site exists for: our link anonymizer strips it, so the page you came from stays private. The IP address is a different job. If you want that hidden too, read about Tor.
