Clear your cookies and a site can still know it's you. The method is called browser fingerprinting. This page reads ten places your browser gives itself away, right now.
What it reads stays in your browser. Nothing is sent or saved. Reload and it measures again.
Measuring this browser. The audio check takes a moment.
Ten kinds of tracking, one line each
Each is measured on your device below. Here is what they are.
- Audio fingerprint. Plays a sound you can't hear and takes the result.
- Canvas fingerprint. Draws text and shapes on an invisible canvas and takes the pixels.
- Graphics card. Reads the name of your graphics chip as is.
- Installed fonts. Tests which fonts are installed by drawing text in each.
- Screen size. Takes resolution, color depth, and the size minus the taskbar.
- Time zone. Takes the time zone you live in.
- Language settings. Takes which languages you use, and in what order.
- Cores and memory. Takes your CPU core count and roughly how much memory you have.
- Browser identity. Takes your browser name, version and operating system as is.
- Touch input. Takes how many fingers your screen can track.
What this tool does and does not do
It does not block anything. Brave has blocked fingerprinting for six years and Firefox for three. Free extensions do it too. There is no reason to compete with that.
It shows you. When audio fingerprinting was found on AliExpress in August 2026, people were angry less about the taking than about the hiding. The code was obfuscated and nobody said a word. This page puts it in plain view.
It does not send. Your readings stay in this browser. Handing over your fingerprint to show you your fingerprint would make no sense. One thing to know: this site is served through Cloudflare, which logs visits. We did not add that, but it goes out under our name, so we say so. Your readings are not part of it.
It says what it does not know. How many people share your fingerprint takes a statistics server to answer, and we have none. So the numbers here are EFF's published observations, and the page says so.
