Privacy settings and fingerprint exposure
Cookies and local storage describe storage available to this page; they do not establish your third-party cookie policy. Permission checks read existing states without requesting location, notifications, camera or microphone access. Canvas and WebGL show rendering signals available to the page.
How to reduce exposure
Review built-in tracking protection, site permissions and unused extensions. Retest after changing a setting and check that everyday websites still work. Run the WebRTC and DNS tests separately when checking a VPN or proxy.
This page does not run a cross-site tracker-blocking experiment or check past breaches. Its results cannot establish complete anonymity.
Frequently asked questions
Does allowing cookies mean my browser is unsafe?
No. Cookies support logins and preferences. The cookieEnabled value on this page cannot determine whether all third-party cookies are blocked.
Can this detect every tracker?
No. This page checks accessible browser capabilities and signals. It does not enumerate extensions or inspect all network requests on other websites.

WebRTC Leak Test
Compare WebRTC public ICE candidates with your HTTP IP address. Check VPN or proxy address exposure, local mDNS protection and STUN status.
DNS Leak Test
Observe recursive DNS resolvers with a dedicated probe and compare them with the DNS provider expected for your VPN, proxy or DNS-over-HTTPS setup.
