Frequently asked questions

What is browser fingerprinting?

Tracking you by combining many small details about your device and browser into an ID that works even without cookies.

How can I reduce fingerprinting?

Use a browser with fingerprinting protection (Firefox, Brave, Safari, Tor Browser), keep it up to date, and avoid unusual extensions or fonts.

Is any data collected?

No — the fingerprint is calculated in your browser and never sent anywhere.
