Storing data on a user's Google's account

问题:

Is there any way in which a PHP powered web app can store data in a user's Google account? (after requesting permission from the user)

Basically I want to stay away from storing private user data on my server.

App will be handling mostly documents / text data.

回答1:

There is the google docs api: http://code.google.com/apis/documents/

But if want private data for the app, you'll need to store it somewhere else than Google. With OpenAuth (or OpenID) you'd not need to worry about personal info.
