Browser Fingerprint & Disguise Score
Nine fingerprint categories plus a six-dimension consistency score, all computed in your browser.
Disguise Score
Runs in your browser · nothing uploadedWeighted across 6 consistency dimensions (max 100)
Fingerprints are computed locally in your browser; the server receives none of them · How to improve your score

What makes your browser unique
Even with no cookies, the combination of your GPU (WebGL renderer), Canvas rendering quirks, installed fonts, plugin list, audio stack behavior and screen metrics forms a fingerprint that identifies your browser among millions. This page computes a digest of nine categories locally.
The disguise score
Beyond raw fingerprints, the score evaluates consistency: does your timezone match your IP location, does your browser language, is WebRTC hidden, does DNS follow the same exit. A self-consistent environment is what risk engines trust — and what this tool helps you verify and fix.
Nothing leaves your browser
Every check runs locally. The server never receives your fingerprint — only an aggregated, anonymous count of checks is kept for the site-wide Network Pulse statistics.

Frequently asked questions
Is a "rare" fingerprint bad?
Rarity makes you more trackable but is not inherently suspicious. Millions of real users have uncommon GPU/font combinations. Risk engines weigh rarity together with consistency signals.
Can I make my fingerprint more common?
Fingerprint-spoofing browsers (and some privacy extensions) present randomized or popular configurations. Beware: a bad spoof creates internal contradictions — a Mac UA with Windows fonts — which is worse than no spoofing.
Why do results change between reloads?
Randomized spoofing extensions intentionally re-roll fingerprints. If values change without any extension, the metric is environment-dependent (e.g. audio floats) — the stable categories are the ones that matter.
Does incognito mode change my fingerprint?
Only marginally — it clears storage and cookies but keeps GPU, fonts, screen and audio characteristics. Fingerprinting defeats incognito by design.
