Yes, I do the same, I use Resilio. I thought about switching to Syncthing, but my NAS supports Resilio out of the box, so I kept using it. I let my .git folder to be synced between devices and I never actually pushed anything to a "proper" git forge - I can't think of a practical use case for pushing my notes to GitHub/Gitlab.

My git-autocommit technique only for tracking unforeseen changes - I was using Orgzly on Android, and one day I tried using its sync feature and it borked up a bunch of my notes, creating duplicate files, etc. I didn't like that.
