There's really a lot more you can look at here. Lot's a prior art on super-cookies and fingerprinting: https://coveryourtracks.eff.org/ https://amiunique.org/

Both linked in the Sources & Confessions modal at the bottom. Cover Your Tracks is the spiritual ancestor of this whole piece. amiunique is more rigorous; this is the editorial cousin.

Brutally dark site doesn't seem to show much to my eyes. No modal appearing at the bottom.

With javascript off it just stalls at "reading" forever. There are certainly some viewport properties and other things it does know even without JS execution, but the mitigation is significant. And the page itself (the JS application) cannot act on that data or communicate it. Instead it has to be processed by some other application on the backend or wherever. Not in my browser by my computer.

I can't help feeling that if you're turning JS off, you might as well turn off your computer to protect your data.

This site actually works just fine without JS.

I guess I shouldn't be surprised that it gives my exact GPU, but that was surprising to me. Just so everyone knows, its an AMD Radeon RX 6900 XT and I paid way too much for it during the covid/crypto price explosion when they were sold out everywhere. Still a bit raw about that, but it is an excellent card on Linux (fedora)

The GPU string really is the spicy one combined with screen + fonts it's enough to single you out across most of the open web. The card itself is a tank.

Yea that is a strong fingerprint. Especially if any of the other things were correct or someone has a way to model your behaviors. How long you scroll vs how often you type etc. and somehow that's still not enough for big tech and they need biometrics, photo IDs, etc.

I appreciate the intent here, so this is constructive feedback: - Some of the numbers are off, eg "Your browser allocated 39322 MB of storage to this page alone" - low contrast in dark mode makes text hard to read

The 39 GB number is a bug. I was reading quota (browser allow-up-to ceiling) and calling it "allocated." Fixed; pushing now. Contrast is intentional but I hear you. not changing it but noted, and a cleaner reading mode is on the to-do later.

Contrast is a violation of accessibility guidelines.

The website is pretty & the overdramatic copy is fun, but there's much better fingerprinting demos out there.

The number of data points shown here is low - there's plenty more it could be checking - & a good number of them seem to be wrong (it's only detecting one as explicitly "withheld" but I believe a few of them actually are, leading to garbled output).

Needs some QA.
