That's just your assumption. VPS != Google. It's just a virtual machine running on some HW. I agree that if that HW is not owned by you, it can be a problem. If that's a problem you can just add another layer of encryption to the mix, like a GPG command. I can and do own that HW. At least as much as one can own anything - it's located in my appartment. You can just as well run the web server from your own workstation/laptop. The only reason to put shared files on other computer is that the other computer is more available.
