Is your browser giving you away?
What every site can read without any permission: your time zone, language, screen, graphics card and more.
Besides your IP address, sites can read many properties of your browser. Each looks harmless, but together they form a “fingerprint” that can recognise you even without cookies.
A VPN hides your IP address, but your time zone or language can still give away where you really are. This page reads everything in your browser only; nothing is sent to us.
Frequently asked questions
Why does my time zone matter?
Even if the VPN makes you appear in another country, your browser's time zone shows your real region. Some services use that mismatch to detect VPN use.
How do I reduce my fingerprint?
Keep few extensions, use a browser with fingerprinting protection (Firefox strict mode, Brave, Tor Browser) and use it together with a VPN.
