Browser fingerprint test
The signals below are readable by any website you visit — no cookies, no prompt. Together they often identify a browser uniquely. Nothing here is sent to us; it's computed and shown locally.

Why it matters
Fingerprinting lets trackers and fraud systems recognise a device across sites and across cookie clears. More unique values = more entropy = easier to single you out. Anti-fingerprinting browsers (Tor Browser, Brave, Safari's protections) deliberately return generic values here.
What's collected
- User agent, platform, language list, CPU cores, device memory, touch points.
- Screen size, pixel ratio, colour depth; timezone and UTC offset.
- A hash of a rendered
<canvas>and of the WebGL vendor / renderer string. - A short font-availability probe and an audio-stack hash.
