What it does is relies on your IP address and cookies overall.
Check on their main website at https://fingerprint.com/ and you’ll see a box you can toggle that says I’m a Developer
When you do that, it shows things like below:
So what it explains is it’s checking:
- Browser used
- Your IP address (and its location)
- Your timezone
- OS used
- If you have any cookies/cache from visiting the site before.

This is why if you check on a normal window and then open something like a Private With Tor you’ll see it says your Tor visit is the first time you’ve been there.
To further example that, I just launched a Private with Tor and look what it says:
Compared to another one:
So they are seeing the one profile where they have logged my IP Address. So they just are using that to say they know me.
If nothing else this shows the importance of using a VPN or proxy in addition.
