What the fingerprint test is for
Websites can recognise a browser without cookies by measuring small details: how it draws text and shapes on a canvas, which graphics card WebGL reports, how its audio processing rounds a sound, which fonts are installed, and its screen, time zone and languages. Together these make a browser fingerprint. This test takes the same measurements in your browser and shows them with a combined fingerprint, so you can see what is exposed and whether your browser protects you by adding noise. Nothing is sent to us.
Frequently asked questions
Can I stop browser fingerprinting?
You can make it much harder. Use a browser with fingerprinting protection, such as Brave, Firefox with strict tracking protection, Safari or the Tor Browser, and avoid adding unusual fonts and extensions. Blocking known tracker scripts also stops many fingerprinting scripts from running at all.
Does a VPN or private browsing stop fingerprinting?
No. A VPN changes your IP address and private browsing clears cookies when you close the window, but your browser draws, renders and reports its fonts the same way, so the fingerprint stays the same.
Is fingerprinting allowed?
European regulators treat reading information from your device like cookies, so using a fingerprint to track you generally needs your consent there. It is also used for fraud prevention, for example to spot a stolen account being used from a new device.
