I was in the same boat… I just wanted a simple god damn self-hosted cloudStorage without any nitty gritty or all the bloat that comes with most local/self-hosted cloud solution…

Syncthing is good, but not really a cloud storage solution (I love syncthing and I use It to sync all my backups !!).

Give SFTPGo a try :) It has also a WebDAV functionality if you wan’t to use it that way ! It just plain file storage with security features. However, not sure there are any application available, it mostly used it as web application :).
