Hey, good to see this here. I've been told to take the tin-foil hat of by family and friends before, so I think that sums me up a bit haha.
I'm running Arch linux, on laptop and desktop, I also use Mullvad browser, which comes with UBlocm Origin and NoScriot. Some sites break, but then I fall back to Brave.
I also have GrapheneOS on a Pixel 5. I try to use as much FOSS app downloaded from Github repos as possible. Obtainium is a godsend for keeping these up to date. I use Aurora store for Play Store apps, which are only installed in the Work profile, and I have sandboxes Google Apps installed I'm both profiles.
At home I run Pi-Hole with Unbound as a local DNS. This also breaks some things, but I probably dont want them working anyway haha.
I also self host Bitwarden as a password manager and use ProtonMail for email.
Phew...
Next steps are to get Nextcloud working for photo backup, and shared calendars between me and my partner. We've been using something called Time tree for years, but its full of ads.
