Browser Privacy Score

The Browser Privacy Score checks privacy-relevant browser signals and turns the visible protections and exposure into an explainable score. It gives an immediate, focused result with no signup, explains the important limits beside the output, and keeps the workflow as private as the implementation allows.

What does a browser privacy score represent?

A browser privacy score combines observable browser protections and exposure signals into an explainable checklist. It summarizes fingerprinting surface, WebRTC behavior, passkey capability, and related features so users can see which detected conditions raised or lowered the result.

Checks are assembled from the site's local feature-detection and privacy tools, with network access only where a test inherently requires it. The score is not proof of anonymity or a universal browser ranking: sites combine signals differently, defaults change by version and platform, and extensions or account state can materially affect tracking.
