I can't run with full authority on Android, however. My own apps can't access my own data from other apps that I run. This is not something I can forego on my main computing device. I'm willing to tolerate it in a phone because it's just a tool; I wouldn't use a phone to store data I wouldn't mind losing.

What kind of solution are you looking for here? The ability to sign your own apps with a platform signature?

The ability to go in and grab your own data (which you have to do using some app or another), and do whatever you like with it, such as back it up, move it, inspect it, or try to get the data into a new app because the old app no longer runs for some reason.
