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

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
Is there no add on, for Firefox, for example, to stop or confuse fingerprinting?
Any suggestions?
For Android.

i used to think that firefox on linux and as plain-jane-generic as you could get besides windows; but no, i'm ultra unique:
Yes! You are unique among the 5084762 fingerprints in our entire dataset.

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
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.

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

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

Only a handful of data points surfaces by this website come from JS APIs, most are either header-based or some other browser behaviour that is independent from JS
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.
This volume requires JavaScript. That is part of the point — your browser is what is being read.
Looks like I'm safe

Really interesting and slightly scary, thanks for sharing!
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

Funny how websites can read the gyroscope. It can also be used as a microphone. https://crypto.stanford.edu/gyrophone/

I'm glad it acknowledges explains the impacts of anti-fingerprinting measures. I've seen some others assume that a random canvas is unique rather than one of the many people randomising it the same way, leading to a false "unique" assessment.
Your browser appears to be returning the viewport in place of the real screen — anti-fingerprinting at work. The substitution is itself distinctive.
Your browser masked your graphics processor. Firefox and Safari have started returning generic strings — "Mozilla", "Apple", "or similar" — instead of the real renderer. The fact that yours did so tells us, with reasonable confidence, which browser you are running. The mask is also a fingerprint.

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
This post helped me discover that my SurfShark VPN built-in kill switch does not work within the Android app. My home IP was showing.
I turned kill switch on at the OS level and my IP was correctly showing the VPN IP.

Amiunique.org
Your device carries these typefaces, of the seventeen commonly probed by fingerprinting checks. The specific combination of fonts on your device is nearly unique — like a fingerprint made of letters
What the fuck why is my browser telling random websites what fonts I have installed? Shouldn't that be completely irrelevant to everyone except me and my particular device?
It should be, yes. But browsers like Chrome are literally made by the company that stands to profit from fingerprinting you, so they're always going to be made to make it easy to do just that. Firefox at least has “resist fingerprinting” option which apparently can limit font visibility to only base system fonts rather than fonts you installed and language-pack fonts. LibreWolf has this on out of the box.

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

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! 
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

Well then I am glad that it got most of it wrong. I don't even put thaat much emphasis on fingerprinting countermeasures. Apparently, using Firefox in a private tab is enough.
I definitely have misleading information on there, which is great, but I probably need more.

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.
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 🤔
