About this tool
This tool checks what information your browser exposes to websites. It tests Do Not Track, cookies, WebRTC leaks, canvas and audio fingerprinting, WebGL vendor, and hardware details. Everything runs locally in your browser.
Understanding browser fingerprinting
Websites can identify you without cookies by combining unique browser characteristics into a 'fingerprint'. Canvas rendering, WebGL vendor strings, installed fonts, screen resolution, and hardware specs all contribute to a unique identifier.
