Browser Privacy Checker

A VPN hides your IP address, but sites can still recognize you other ways — through your browser and device settings. Below is everything any site can see without special permissions.

What is a digital fingerprint

Even without cookies and without your IP, sites can collect a unique combination of your browser and device settings — this is called fingerprinting. The canvas-fingerprint hash below is often unique to a specific combination of browser, GPU, and operating system.

A VPN doesn't hide this kind of information — that takes separate browser settings (for example, Firefox with resistFingerprinting enabled, or a tracker-blocking extension).

A VPN is only part of the picture

404 VPN encrypts your traffic and hides your IP, but it doesn't replace browser privacy settings. Use both together for the strongest protection.
