I use a different Gmail account for maps.
I use DuckDuckGo for search.
Instead of Google I use third parties for everything else they do that they listed on here that they track.
My history/activity on their servers was limited outside of tracking my location.
I would love a decent alternative to Google Maps but nothing I’ve used comes close.
(Disclaimer, below is about maps, and my personal anecdote. Ignore as necessary.)
(Though I must say, I'm in the process of trialing a new mapping app. Because Google have failed me.
I live in a suburb that was created 2 years ago. It replaced part of an old suburb, and a new area that hadn't been assigned. They created a new postcode for this new suburb too. Two years on, Google doesn't know it exists, so my address doesn't exist. It has my road, but no name, no numbers.
I tried out OSM And+ (via FDroid), and Android mapping program, based mostly on OpenStreetMaps. It has my suburb, and my address. Since about 1 year, 10 months ago. The directions are flawless, and it has a decent GPS voice.
However, it doesn't have as decent coverage of the Points-Of-Interest stuff that Google Maps has, but I'm fine with that, never used them anyway, apart from finding the nearest fast food place or gas station on a long trip.
And the public transport stuff is hit & miss. But I can't keep up with bus timelines in my area myself, they change about once every 3 months because of strikes.)
And it's been saying that saying that since I clicked 'Activity controls' on the side there, and unticked every box.
I don't for a moment believe it's all Google has on me, but you don't have to live with it.
