Cash.

VoIP instead of cell service. VoIP is kyc but I can use it without celltower tracking. I keep my phone in airplane mode.

GrapheneOS and lots of Foss apps.

Every account gets a unique login - name, password, email alias. I also give as much fake information as I can. 2fa when it available.

I have no accounts with any of the big tech.

I’m planning on buying a used Windows laptop and installing Linux. Pop_OS to start as I have an eBook on that os.

Edit: corrected autocorrect.

I cover my webcams, I have almost entirely de-Googled (since they’ve been attacking Invidious, I’ve had to resort to watching the videos on YT if they aren’t on PeerTube or Floatplane or whatever), I use Linux and BSD, I am planning to switch to GrapheneOS at some point, and I try to avoid software and services from countries with problematic governments (e.g. China, Russia, USA). I am also using local software, with data sychronised via SyncThing (currently just my notes and passwords, but the list is growing).

I also use Mullvad Browser when available, and either Brave or Epiphany when it isn’t.

I am still on the lookout for a decent search engine, though, as all of the ones I’ve used are either not as private as I thought (e.g. Ecosia, Qwant), or are broken (e.g. LibreY), or did something I disagreed with (e.g. DuckDuckGo, Brave Search), or are hostile towards VPN/Tor users (e.g. Startpage), or didn’t have good enough indexes (e.g. Mojeek), or became unavailable to me (e.g. Peekier, MetaGer).

I try to blend in and avoid posting my main privacy activities in public.

Despite what they say, while obfuscation may not be secure, it sure helps with privacy.
