Can I prevent browser fingerprinting entirely?

Complete prevention is nearly impossible without making your browser look identical to every other browser. The best approach is to use Tor Browser, which standardizes fingerprint vectors.

What does a high uniqueness score mean?

It means your browser's combination of settings and hardware is rare. Trackers can re-identify you across different websites even without cookies.

Why does the WebRTC check contact an external server?

WebRTC can expose your real IP even behind a VPN. The check contacts a public STUN server to detect this leak. This is the only external connection the tool makes.

Does changing my user agent help?

Minimally. User agent is just one of dozens of fingerprint vectors. Changing it alone may actually make you more unique.

Identity Audit

Browser fingerprint analysis. Reveals what trackers see when you visit a site.

Browser fingerprint analysis. Reveals what trackers see when you visit a site. Open the tool and click "Audit My Browser" to collect fingerprint vectors. Review your WebRTC leak status and system information panel. Examine each fingerprinting vector to see what data your browser exposes to trackers. Check your uniqueness score to understand how identifiable your browser is. Canvas, WebGL, Audio, and Font checks run in your browser. The WebRTC leak check contacts Google's public STUN servers (stun.l.google.com) to detect IP leaks — no data is sent to They Didn't Ask servers.
