Not quite. It requested to play DRM protected content.

im on linux though. the page even says earlier that im on a linux box.

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.

Not sure what went wrong for you but I'm running an i9

I don't think my desktop computer has a battery

Windows audio settings shows 3 inputs and 5 outputs currently

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

> You're inside a virtual machine.

It's wrong. I have Hyper-V and VirtualBox installed on my machine, maybe it has some effect?

> You use Microsoft Office

No, I don't. It was installed previously, but my license expired.

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

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.

Nice got different fingerprint across firefox and chrome on android

TZ wrong.

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

Just tested this.

But also...

> Voice list = Microsoft David - English (United States) [snip]

Considering that this is tested on Windows 11, I think your Linux detection is wonky.

i'm actually using a macbook neo and my display resolution is not 1920x1200

no i don't

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