What your browser reveals
Your address, your agent, your browser and everything else a page learns about you without asking.
What this request already told the server
Not looked up anywhere. Every value here arrived with the request that fetched this page, and every site you visit receives the same ones.

What your browser says when asked
Read in your browser and sent nowhere. None of it reaches this server unless you copy it yourself.
Good to know
- Nothing on this page leaves your browser. The top half is what the request that fetched this page already carried; the bottom half is read on your own machine and never sent back.
- Together these values are a fingerprint. Each one is shared with thousands of people; the combination often is not — which is how a site can recognise a returning visitor with no cookie at all, and why a browser that cares about this hides some of them.
- An IP address names a connection, not a person. A mobile network can put thousands of subscribers behind one, and a home address usually changes when the router is restarted.
- Nothing here asks for a permission. Your location, camera, microphone and the contents of your clipboard all need one, and none is requested — what is shown is only whether your browser would let a page ask.
- The user-agent string is mostly history: every browser still opens with Mozilla/5.0, Chromium freezes its minor version at 0.0.0, and Windows 11 reports itself as Windows 10. The user-agent tool takes one apart and explains each part.
- A row that says “withheld” or “not said” is usually your browser declining, not a fault here. That is the browser doing its job.
