Privacy & Security Tools
Check what websites know about you — IP address, DNS leaks, WebRTC leaks, and browser fingerprint.
Detecting your IP address...
DNS Leak Test
A DNS leak means your ISP can see which websites you visit, even if you're using a VPN. This test checks which DNS servers your browser is using.
WebRTC Leak Test
WebRTC can reveal your real IP address even when using a VPN. This test checks if your browser is leaking your real IP through WebRTC.
Browser Fingerprint
Every browser has a unique "fingerprint" — websites use this to track you even without cookies. See exactly what your browser reveals.

When your DNS queries bypass your VPN and go directly to your ISP, revealing which sites you visit.
What is a WebRTC leak?
WebRTC can expose your real IP even through a VPN, because it communicates directly with STUN servers.
What is browser fingerprinting?
Websites combine browser data (screen size, fonts, timezone, etc.) to uniquely identify you without cookies.
