I use that to sync savestates between RetroArch on mobile, desktop and laptop. no need to worry and I can resume my games wherever I am.

SyncThing, while indeed amazing and my goto for personal file sharing, might not go well with your corporate policies. An alternate program, like InSync, allows you to disable telemetry on DropBox, OneDrive and Google Drive at the same time, and is easier to justify.

Syncthing is indeed amazing. I've been using it for the last years, had some problems way back, but haven't seen a single issue over the last year or so.

Worth mentioning that Syncthing doesn't have a cloud part, while DB does. That said, I've been running it since the very beginning, even before it became public/known, and it had never failed me so far.
