Rather than a promise, I’d like to see things like this written into the actual contract of paid services. Even if the try to limit the liability to just what you paid them, it’s still a useful barrier to selling your data or exposing it. In the case of them blatantly selling it to “partners” you could still go after them for the value they gained by breaking the contract and selling your copyrighted information.
