Could the app not take a copy of the per-user private key when it's generated? (I know nothing about mobile security models).

  Or when you paste in a key to the app to use for decrypt. Not specific to mobile. Give an app data and it can do what it wants.

    I thought maybe mobile OSes might have a decryption sandbox, so apps could manipulate keys without having full access to them.
