Exposure score
Each signal below carries an entropy weight from public fingerprinting studies — the bits of identifying information a typical value adds across a population. Because many traits are correlated (your OS largely predicts your fonts, GPU and user agent), the identifiability score does not just add them up: traits are grouped into correlation clusters and discounted, so the total tracks the ~18–22 bit ceiling real studies observe. Read it as an upper bound — on a real crowd many browsers share more than this implies. The Measured here figure is the actual rarity among this site's visitors; the exposure percentage reflects how much of your device and network configuration is visible to sites you visit.

WebRTC leak test
WebRTC can expose local and public addresses even behind a VPN. Modern browsers usually mask local IPs as random .local names.

DNS leak test
Your browser resolves a random one-time name that only this site's DNS server can answer, revealing which resolver actually handles your lookups. Behind a VPN, answers arriving from your ISP's resolver are a DNS leak. Only the resolver's address — and, if it forwards one, your network prefix rounded to /24 (IPv6: /48) — is kept, for ten minutes.

IPv6 leak test
Many VPNs tunnel only IPv4 and let IPv6 traffic take your normal route, exposing your real network. This forces one request over each protocol and compares which networks they exit from.
