I am trying to re-adjust how much effort I want to put into privacy concerns. Too much stuff I'm using isn't working properly or using a lot of my mental resources that I need elsewhere.

For (a bad) example: I recently performed a half-switch from my self-hosted Nextcloud instance to ProtonDrive, in the hope that it would spare me the stress to maintain my private Nextcloud. Unfortunately, it doesn't, as basic functionality like cross-device-sync is not possible (there isn't even a client app for Linux, as of yet).

This brings me to the question: have you found any services/apps/stuff that significantly eases your life while still being privacy friendly? I know, this is a broad question, but I think this is for the best as this thread then maybe even has use for other users.
