Browser Privacy Check & How to Fix Leaks
Websites and trackers read dozens of small signals from your browser-some can identify you even behind a VPN. Run this privacy check to see what leaks and how to fix them.

What Your Score Means
Low (0-10)
Real IP exposed via WebRTC, GPC off, most trackers reachable.
Medium (11-20)
Some protections active; consider enabling GPC and hardening WebGL.
High (21-30)
Strong privacy posture; continue periodic checks.
How to Improve Browser Privacy
- Keep WebRTC mDNS on, or block WebRTC entirely if you don't need it.
- Enable Global Privacy Control (GPC) and Do Not Track.
- Use anti-fingerprinting or a strict protection mode (containers/profiles).
- Harden WebGL; prefer software rendering in hardened profiles if needed.
- Use a content blocker (uBlock Origin) and disable 3rd-party cookies.
- Prefer VPNs with WireGuard and audited no-logs policies.
- Separate work/personal browsing; don't reuse logged-in identities.
- Run this check after browser updates or installing new extensions.
FAQ
A WebRTC leak happens when your browser exposes network addresses through WebRTC ICE candidates. In some setups, that can reveal your real IP (or local network details) even while a VPN is on.
GPC is a browser signal that communicates your preference to opt out of the sale/sharing of personal data. Some websites honor it to reduce tracking and targeted advertising.
Canvas and audio APIs can be used to produce stable signals that help trackers recognize your browser across sites. Hardened browsers may randomize or reduce this data.
A VPN hides your IP from most websites and encrypts traffic to the VPN server, but it does not stop browser fingerprinting or ad trackers by itself. Pair it with browser hardening and a content blocker.
Use a content blocker (like uBlock Origin), disable third-party cookies, enable strict tracking protection, and consider containerized profiles for separate identities.
No. This privacy check runs entirely in your browser. The results shown are computed locally and are not sent to our servers.
Blocking behavior can vary by browser, extensions, DNS filtering, and network policies. Some endpoints may be blocked while others are reachable.
Run it after browser updates, VPN changes, or installing new extensions. Small changes can affect your privacy posture.
