Tracking Exposure Score

How unique — and trackable — is your browser? We collect the same signals advertisers use (canvas, WebGL, fonts, hardware) and estimate how identifiable you are, then name the biggest leaks.

100% local — nothing is sent anywhere. The score is an estimate of identifiability based on typical browser-population distributions, not a comparison against a stored database.

🕵️ How tracking works in 2026

AdTech has moved past cookies to fingerprinting: combining canvas rendering, WebGL renderer strings, installed fonts and hardware details into a near-unique ID that follows you without any cookie.

🧮 The score

Each signal contributes estimated bits of entropy. More bits = more unique = more trackable. We sum them into a 0–100 trackability score and flag the highest-entropy leaks.

🛡️ Reduce your exposure

Use a privacy browser (Brave, Tor, Firefox + resistFingerprinting)
Block third-party scripts (uBlock Origin)
Avoid rare fonts/extensions that make you unique
