Now where do I start lol, I've been on this journey for a few years, and I'd say, take it one service at a time!! I'll try and list most of my apps/services etc.

Phone running grapheneos

Browser - vanadium (graphenes hardened browser)

Maps - organic maps

Mail - protonmai

Calender - protonmail

Notes - standard notes

YouTube - newpipe

App store -F-Droid

Messaging - signal and threema

File sync - syncthing

Password managing - bitwarden

Gallery - simple gallery

Camera - stock grapheneos camera

Ad blocking - 2 piholes setup

And one of the hardest was google photos..... Overcame that with self hosting photoprism..... I have syncthing sync my camera roll to a hard drive attached to one of my raspberry pi..... 3am it rsyncs to a permanent location, than rsync to another hard drive, than have a script that adds it to the photoprism library an hour later, sounds hectic but perfect once setup....

And if you want to go even deeper and not use google or any other provider as your DNS, if you have a pi or any other computer running 24/7 can run your own recursive DNS resolver with unbound..... Hope this helps some people, may have missed a few 😂
