FAQ
What does this privacy audit check?
It checks 25+ indicators across 5 categories: fingerprinting (canvas, WebGL, audio, fonts, hardware), tracking (cookies, DNT, GPC, ad blockers), leaks (WebRTC, referrer, IP), configuration (HTTPS, permissions, storage), and security (browser version, isolation, secure context).
Is my data sent to a server?
No. Every test runs entirely in your browser using JavaScript APIs. No data is transmitted, stored, or shared. The only exception is the optional IP check, which uses a single request to detect VPN usage.
What is a good privacy score?
A score above 75 (grade A or B) means your browser is reasonably well protected. Most users score 30-50 with default settings. Scores below 30 mean your browser is highly trackable.
How can I improve my score?
Follow the recommendations provided after the test. The most impactful changes are: install an ad blocker (uBlock Origin), disable WebRTC, block third-party cookies, and enable Do Not Track.
What is browser fingerprinting?
Browser fingerprinting is a tracking technique that identifies you by combining dozens of browser properties — screen size, installed fonts, GPU model, audio processing, etc. Unlike cookies, you cannot delete a fingerprint because it is derived from your hardware and software configuration.
Does the Before/After comparison work across sessions?
Yes. Snapshots are stored in your browser's localStorage. You can save a snapshot, close the tab, make changes to your browser, return later, and compare the results.
