Overview
This test reveals what information websites can learn about your browser through common fingerprinting techniques and checks whether your browser protects against these tracking methods. All tests run entirely in your browser — no data is sent to any server.
Browser fingerprinting combines multiple signals like canvas rendering, WebGL parameters, installed fonts, and hardware details to create a unique identifier that can track you across websites without cookies. Privacy-focused browsers like Brave and Firefox with enhanced tracking protection actively defend against these techniques.
