Describe your issue
As the title says.
I host my Yunohost instanse at Hetzner. The VPS comes with Debian preinstalled, and of course Hetzner has access to that. But when I install Yunohost on top of the Debian installation? Will Hetzner have access to the Yunohost installation and its files?
Answering your concern the way I understand it: the filesystem is not encrypted in anyway by default YunoHost installation, so if your VPS provider decides to snapshot the VM and examine its contents all the files will be there, in plaintext.
