What any website can learn from your browser without cookies or permission, the privacy signals you send, and practical ways to reveal less.
Browser privacy report
Loading the browser privacy report. It runs in your browser.
Five kinds of identity
Network identity: your IP address, shared by everyone on your connection and changed by a VPN.
Browser characteristics: version, languages, fonts, graphics and settings, the same on every site you visit.
Device characteristics: screen, processor threads, touch support, time zone.
Cookies and storage: identifiers a site saves on purpose and reads back later.
Fingerprinting: combining characteristics into an identifier that works without cookies.
Reducing what you reveal
Use a browser with fingerprinting protection: Firefox (Enhanced Tracking Protection, Strict), Brave, Safari or Tor Browser.
Turn on Global Privacy Control; in some places sites must honour it.
Block third-party cookies.
Keep extensions few: each one can change what sites see.
Use a VPN to change your network identity. It does not change your browser fingerprint.
Questions
Does this test say how unique I am?
No. That needs a database of many visitors to compare against, and this site keeps none. The characteristics hash shows what a site could use to recognise this browser on a later visit.
