Wait, what? Anything you do in any Google app is "externally". That's what the cloud is.

You're willing to put data in Google's hands, and have Google process data in way X, but you don't want Google to process those data in way Y, which has pretty much identical security and privacy properties?

Anyhow, the solution here is not to use Google services. You shouldn't be doing that anyhow.
