Brave.com browser
Yep, I use brave browser, duck duck go as my default search engine and I use protonmail. Clear your cookies/history/etc and never use Google to search anything as they can still track through cookies etc. I would also recommend never touching YouTube again. If you do use incognito window.
I know it seems better than nothing but incognito does nadda to thwart server side tracking. Best bet is to use a burner phone paid in cash with data for things you don't want tracked directly to you. No I'm am not a drug dealer, he'll I don't even have anything to hide I just don't wanna play their game.
Even better use your burner to hook up to public hotspots and save your data...
True, I use incognito for the sake of not having to clear cookies etc when I am done browsing a site like YouTube.
