Thanks for sharing, I was already using a decent anti-fingerprinting browser (Fennec) but the fact that it gave away my timezone made me research a bit more and I'm now on IronFox, which has a toggle to spoof it, and reports a fake screen resolution. Great! I'm now unique on coveryourtracks though

My jaw dropped when I read the what angle my device is being held at, how many times I scrolled and tapped, what my position is!!!
How is this even legal?!
I always thought they just took my location, my device name etc. I had no idea it's this deep.
I hit it with Firefox and it gave 24 points. Firefox refused to disclose my battery level. But did give it my angular geometry.
I opened it in Brave and it lied about my screen resolution and colored up my fonts, my battery. It refused to give up my angular geometry.
Why the hell doesn't firefox just include some of those white lies?
central europe, maybe its due to architecture the isp has wifi access points around the city and people connect to them
back when it was starting there wasnt even isolation between clients, we used to send random shit to printers on the network as kids
It identified my many-years-old phone with "360x760 pixels rendered at 3x density" screen as "recent, high-end display". Bitch, this wasn't even high-end when I bought it. It was small, it was cheap, it was barely "recent" when I bought it.
Vibe coded af, how has nobody spotted this. The website swears the text was written by a human, and either they have contracted chronic GPT-virus or are an LLM
edit: this is made by Rise Up Labs which is an ai psychosis company
How can you tell that it was vibe coded? Genuine question.
AI is quite good at web design now, but it still has a distinct style. Claude in particular LOVES to mix serif and monospace fonts. This isn't necessarily a guarantee based on just that, but it did trigger my alarm bells.
The second biggest thing is the language. LLMs absolutely SPAM slightly vague, short phrases separated by punctuation.
The language on each data point also is pretty repetitive which implies either sub agents were called or the model was asked individually to write something about it in a specific tone.
The final nail in the coffin was the company that made it, Rise up labs, which advertised all their AI software on their home page
One clue to me is the "how many times you moved" statement. One actual human "move" is worth hundreds of what the site calls a move. A human would notice that but the reality of it means nothing to an AI.
Secondly just the language used being quite dramatic but also generic.
LLMs always write with a very dramatic tone. I really hate that high impact language now.

"We know your IP address". No kidding, that's how IPv4 works, even if the browser wasn't ~~leaking~~ offering it.

This ones my fave: https://amiunique.org/fingerprint
It shows the percentages of people who use your same browser features (called similarity ratios), and can determine whether you're unique in their dataset. Can help for tweaking browser settings to try to make yourself not unique.
Yay, I'm completely unique! I won!
Wait a minute

This volume requires JavaScript. That is part of the point — your browser is what is being read.
Looks like I'm safe

all trackers hate this one trick
Unironically a solid way to block a lot of tracking. Although they can still fingerprint you I think.
Nothing makes you more unique than being one of the few people who disable java script
Honestly I would rather they fingerprint compared to running random code from websites.

I wonder, do phones have 6dof tracking (space + rotation) or 3dof tracking (just rotations)
because if it's 3dof I'm calling bullshit on some of this.
I have 7 3dof fullbody trackers for vrchat (cough cough !VRChat@sh.itjust.works cough cough) and they're so damn inconsistent and need to constantly be ready to be calibrated to line up with what your body is actually doing. Having 1 3dof device can definitely detect walking or swinging, no shot it can tell if you're in bed or on a couch

Only 50% correct in my case (similar to Browserleaks), correct the OS, Screenresolution, Country but wrong site, wrong even the ISP

And yet here they are showing me their webpage in darkmode 😒
Well they did say they don't use the information 🤣
Well too bad!
🗿
the data is still there tho
Can't trust vibecoded website tbh cause they're just saying BS there, as longest the javascripts off, it wouldn't be able to obtain the obvious data of your devices
You absolute can fingerprint someone without JavaScript enabled. This article explains what signals a website can use when JS is disabled, and those signals include probing what CSS features your browsers supports.

Unfortunately it looks like the demo link in their article doesn’t exist anymore. It definitely used to, because I remember testing it few years ago. But the write up is still good.
Looks like the demo is open source: https://github.com/fingerprintjs/blog-nojs-fingerprint-demo

Your screen is 360 by 640 pixels, rendered at 4x density — which means it is almost certainly a recent, high-end display
GUESS AGAIN, IDIOTS! 
How many points of identification are needed to positively ID you? Something like 35 IIRC according to Cover Your Tracks/EFF? Might be remembering wrong 🤔
"31 data points"
Hell yeah! i is ghost.
Time to start installing and uninstalling random fonts everyday.
And then you become even more identifiable cause you're part of the 10 madmen in Google's database who do it
In reality hes the only madmen but switches IPs in between
I have ~2,000 fonts installed. I thought it would say something about it.
Or you could use chameleon browser extension.
It changes your data every 5 minutes
fingerprint.com is an actual tracking company, while the front page doesn't show what it knows it shows weather it has seen you before.
You can setup browsers to randomize fingerprints (tor does this automatically) so while your browser fingerprint is almost always unique you can see if it changes enough so it doesn't recognise you across accesses.
