From the terms and conditions:
The rights that you grant in this licence are for the limited purpose of operating, promoting and improving our Services, and to develop new ones. This licence continues even if you stop using our Services (for example, for a business listing that you have added to Google Maps)
Zack Whittaker on ZDNet takes this paragraph to mean that Google may own your files. I don’t quite agree on that, but of course, terms of service documents can be as clear or vague as the reader makes it out to be. I think the key in the last sentence is the word stop. Does stop simply mean ceasing to login or does it mean after you delete the account? Even further, does it mean Google can use your files even after you delete them from Google Drive?
A statement from Google doesn’t exactly answer my questions.
