Not just google but run of the mill commercial site use fingerprinting. E.g.: https://github.com/jackspirou/clientjs/blob/master/README.md https://github.com/Valve/fingerprintjs/blob/master/README.md

In Google can track surfing habits without need for HTTP cookies

There's a site [1][2] that shows just how bad fingerprinting can get. You enter your name in private mode, close your browser then visit the site again and it has remembered you. It would be great to know exactly what percentage of visitors had your same fingerprint. It uses clientjs [3] which I guess let's the "tracker" choose how strict to be. While it uses a different library, this site [4] can show just how unique you are amongst other visitors. Again that fingerprint will not change even if you close your browser ,wipe your history, restart your computer, etc. 1. https://www.nothingprivate.ml/ 2. https://github.com/gautamkrishnar/nothing-private 3. https://github.com/jackspirou/clientjs 4. https://amiunique.org/fp
