> The tracking method works even in the browser’s incognito mode and is not cleared by flushing the cache, closing the browser or restarting the operating system, using a VPN or installing AdBlockers.

Reminds me of [Cookieless cookies](https://lucb1e.com/randomprojects/cookielesscookies/) but I don’t think it is accurate because I recall visiting this site a while ago, and now it shows that I visited it only once (my current visit). It is either the tracking not reliable or or the admin of web server cleared logs…

This is very interesting, but all browsers I have tried, including non-privacy-oriented ones like Microsoft Edge, give different results between normal and incognito browsing.

It survives Forgetful Browsing in Brave. So is [supercookie.me](http://supercookie.me) as well.
