See how well your browser protects you from fingerprinting. All tests run locally in your browser. Nothing is sent to our servers.
Before we start
This check will probe your browser's APIs to test how well it resists fingerprinting. Here's what you should know:
All tests run locally. No data leaves your browser. Nothing is sent to our servers or any third party.
We test fingerprint surface area including canvas, WebGL, audio, navigator properties, screen info, timing precision, fonts, and more.
No fingerprint is stored. Results are generated in memory and displayed to you. When you close this page, everything is gone.
Source code is visible. All test logic is in this page's source. You can inspect it yourself.
By clicking the button below, you consent to running these client-side diagnostic tests.
Running tests...
What does this mean? Green checks indicate active protection: the API is blocked or returns randomized/generic values. Red crosses mean real data is exposed. The score only counts tests with clear pass/fail criteria. The "Browser Info" section below shows raw data your browser exposes. Check it yourself to see if values look spoofed or real.
