Browser privacy check

Why these values matter

None of these signals identifies you on its own. Together they form a fingerprint: user agent plus screen size plus time zone plus fonts plus a dozen other properties can narrow a crowd of millions down to a handful of browsers, sometimes to exactly one. Trackers use fingerprints to recognise you across sites without cookies, which is why clearing cookies does not always reset who the ads think you are.

The time zone row deserves special attention if you use a VPN. Your connection may exit in another country while your clock still says otherwise, and a site that compares the two can tell something does not add up. That mismatch rarely blocks anything by itself, but it is one of the signals streaming services and fraud systems weigh.

What actually helps

Fingerprinting resistance is mostly a browser setting, not a network one. Browsers with tracking protection can blur or standardise many of these values, and mainstream hardware in a mainstream browser blends into a bigger crowd than an exotic setup ever will. A VPN handles the other half of the problem: it replaces the one identifier no browser setting can hide, your IP address. Check what yours currently shows with our IP checker and leak test.
