You're still tracked, analyzed, and targeted both on and off the web by thousands of companies. Not to mention government snooping and surveillance. Even the social media giants which you deliberately never signed up for are still collecting and monetizing data on you.
Oh I see what you mean. Does this change if you don't use any of Google's products ie. web browser, youtube or search engines?
If you never run JavaScript, don't use an IP traceable to you, then you're probably safe from tracking. But GDPR applies offline too, so your insurance company can't increase your bill because you drink too much coffee and have a loyalty card, without you being able to trace that link.
I don't know how wide their web is. I know they have partnerships with some third parties, presumably some involves tracking that data.
Unless every single person you know also strictly avoids social media, you are still getting tracked by social media companies.
Facebook and Google are known to track non-users around the internet as well.
