Privacy tool
Browser Fingerprint Test
Check which browser and device signals websites may use to recognise you without cookies. The test runs in your browser and shows an exposure score plus the individual signals detected.
What browser fingerprinting can reveal
Websites can combine details such as your browser version, language, timezone, screen size, device memory, CPU hints, plugins, canvas rendering, and WebGL renderer. One signal alone may be harmless, but the combination can make your browser easier to recognise across visits.
How to reduce your fingerprint
- Use a privacy-focused browser or a separate privacy browser profile.
- Block third-party cookies and known trackers.
- Consider browser settings or extensions that restrict canvas and WebGL readouts.
- Keep browser language, timezone, and VPN location consistent when privacy matters.
- Retest after changing browser settings, VPN servers, or privacy extensions.
Useful next checks
Browser fingerprinting is only one privacy signal. You should also check for WebRTC leaks, DNS leaks, and whether your VPN is working as expected.
Frequently asked questions
What is browser fingerprinting?
Browser fingerprinting is a tracking method that uses details about your browser, device, screen, timezone, graphics rendering, and settings to recognise you without relying only on cookies.
Is a browser fingerprint the same as cookies?
No. Cookies are stored data that can usually be cleared or blocked. Fingerprints are inferred from the way your browser and device behave, so they are harder to reset.
Can I completely stop fingerprinting?
It is difficult to stop all fingerprinting while using normal websites. You can reduce exposure with privacy-focused browsers, stricter tracking protection, script blocking, and consistent privacy settings.
Why does this tool show an exposure score?
A true uniqueness score requires a large comparison dataset. This tool instead shows which fingerprinting signals your browser exposes locally and how risky those signals are.
