Incognito basically just means "doesn't show up in my history". There are many, many, ways to track users without needing cookies.

  > doesn't show up in my history AND drop all cookies from all domains. > There are many, many, ways There probably are. I haven't ever seen it work though. If I get into incognito, my ads show something different my normal profile. In theory, they can track you from your OS/browser combination (and many more variables), but is there a way to test it?

    Font enumeration is the big one.

    It isn't theoretical. Google is currently facing a lawsuit (Brown et al v Google LLC et al) for tracking people who assumed Chrome's incognito meant Google would stop tracking them.

      That's a hilarious premise for a lawsuit, because that's never what incognito mode meant.

    The EFF has a great tool demonstrating the method: https://panopticlick.eff.org/ https://panopticlick.eff.org/ It’s not theoretical; it’s used in practice today.
