  And asked to create a WebGL context and to view canvas data. Closed and reopened the browser and revisited the site a couple times, and it thought it was my first and gave me a different fingerprint each time.

    removed it! The latter should not be happening anymore either hopefully
- kuberwastaken 2mo ago
  update: removed it, didn't need it and I use chrome so it didn't pop up haha

This is such a clever technical demo. Do you work for Posthog? LOL

I looked into my ad profile section and saw that I was worth nothing... I'm not sure if I should be happy or not.

  Perks of making this deterministic haha will fix, thank you

  Same issue here. Pixel ratio 1.25 on Linux, Firefox.

On an iPhone like half of the information was wrong and conflicted prior information. And then stopped responding at the gathering ip, etc part.

  Yes, probably detected those, including teams haha

Fun site, but it got some things wrong: - 8 core cpu. I have 24. - devtools open. they are not. - primary language. this one is strange, because I'd think the browser declares it pretty loudly. I have a fairly small regional language set as my primary, but it detects English. - zero permissions. This is not true, Firefox actively opened a permissions button asking to access other apps and services on the machine. I decided to accept it out of curiosity - it didn't change the results in any way relative to blocking it. - first time here. it thinks it's my first time on the page every time I visit.

Good demo of the gap between "no cookies" and "no tracking". A chunk of the analytics industry sells "cookieless" where under the hood it's exactly this - a fingerprint doing the cookie's job. Easy way to tell the two apart: if a tool can recognize you as a returning visitor across days without ever asking, something is identifying you.

I was surprised that it only detected very basic details about me.. and most importantly, it got the display resolution completely wrong!

TZ wrong. Screen resolution wrong. 3200x2200? How does it come up with that?

Excellent! Thanks! It got me thinking, is there any way people can defend from this privacy abuse?

I tried it in different browsers. WebRTC must always be disabled. It’s better to try to work without JS in the browser. Also, the “forget” button worked for one reboot, and then it indicated again that I had visited this page the correct number of times.
