About this check

Everything on this page runs in your browser. Only the location of your IP address for the time zone comparison comes from our own server.
Tor Browser, Brave, Mullvad Browser and Firefox with resistFingerprinting give out common or random values, so the fingerprint matches many people or changes with every visit.
What your browser sends with every request is on the HTTP headers page.
