Throwaway of an ex search engineer here. This can’t work because how would google reliably only give you your information without a login account? They are only useful enough in aggregate to google so they can’t know it is only you with 100% certainty until you log in. AFAICT anyone telling you anything else is probably nonsense fearmongering, or maybe doesn’t understand how sophisticated attackers of google are and hasn’t thought through what happens when you have a logged out way of spoofing someone’s internet behavior to get their whole data.

This is effectively a) putting everyone’s approximate search histories on the internet, or b) outlawing google search’s buisiness model.

The consequences of trying option a and failing even once are so great, I argue if that’s your goal you should ban logged out personalization before anyone deludes themselves into thinking they can do it without leaking everyone’s info publically. I also think that’s going to harm consumers more than it actually helps them but I am obviously biased as an ex google search engineer.
