Thread: Running a website

But when I am running a website, my data is on someone else's server and I don't even know where my data is.

That is a somewhat different issue. You can have your computer that is hosted by somebddy and you can still have your copies of software. So, you still do control the computing that is done. True, you are trusting your data to whoever hosts the machine. He can go to the machine and rip off the data. It is trusting somebody, but at least he doesn't control the computing that you do.
