Managed Nextcloud is definitely easier than hosting it your own. I bet they also have the hardware to guarantee good performance. With any luck Hetzner also offers AI features like face recognition and automated tagging.
But don’t go in there expecting a fully fledged Google Photos alternative. Even when Memories is much better than Nextcloud’s own Photos, it lacks many essential features like easy filtering of your collection. You basically have to sort your photos yourself.
Unless Hetzner offer something on top of Nextcloud file sync is done via Webdav, not sftp or rsync. But basically every OS has Webdav clients.
Calendar and Contacts are also synced via DAV. CalDAV and CardDAV. Works well for me on Android with DAVx⁵.
















Of course that depends on the apps in question and if you are even able to install additional apps in a managed environment.
But not all apps are so limited. The cookbook app for instance saves all recipes as markdown files you can easily share with others, download or backup.
