I moved from GDrive to a hosted Nextcloud solution. It works fine for everything but video files for me. I don’t know if it’s a bug from my host (disroot dot org) and if this ran better were I to host my own server. I could find references to a bug but no solution last year and just stopped using it to move videos around. They would download but be unplayable.
For me, Nextcloud is good for notes, calendars, and contacts as well. Syncs well everywhere. Less good if you’re into to-do’s.
Proton, the company, is just a slightly less evil and smaller Google in a Swiss trenchcoat if you ask me.



I was looking for something similar late last year. I dare say there is no good and FOSS solution right now on Android.
