You can find pretty much all the data that Google has on you - they allow you to examine the history of it. As far as I know they don't track your entire web browsing history but they do record all uses of their sites with your account.
But personally I certainly don't need to be logged in using any of Googles services except for GMail so I'd rather just not build up the history rather than having to go about deleting it (or not because there's so many other things to get distracted by)
Yeah, I think this is where things start to get fairly pointless with avoiding being tracked. I'm imagining that even at a basic level they can match up any Google searches / GMail you use to your IP address and then follow that via Google Analytics.
I'm happily using DDG as a replacemet for most Google searches. But I guess I need to stop using GMail.
I've been a happy customer of https://www.fastmail.com/ for some years now (and used Gmail before). I highly recommend them for anyone considering leaving Gmail. You pay them with money instead of data.
