Google, for all their sins, give you one single location to see everything they collect on you and to delete it, opt out or quit the service.
Nope. From their Terms of Service, topic "Your contents in our Services":
Some of our Services allow you to upload, submit, store, send or receive content. You retain ownership of any intellectual property rights that you hold in that content. In short, what belongs to you stays yours.
So far so good - I'm going to skip a few bits to get to the fun part which contradicts those wonderful words:
When you upload, submit, store, send or receive content to or through our Services, you give Google (and those we work with) a worldwide license to use, host, store, reproduce, modify, create derivative works (such as those resulting from translations, adaptations or other changes we make so that your content works better with our Services), communicate, publish, publicly perform, publicly display and distribute such content. The rights you grant in this license are for the limited purpose of operating, promoting, and improving our Services, and to develop new ones. This license continues even if you stop using our Services (for example, for a business listing you have added to Google Maps).
Not so good - they just rephrased the word "perpetuity" because people started to pick up on it, and their description of "limited" is rather all encompassing IMHO.
Some Services may offer you ways to access and remove content that has been provided to that Service. Also, in some of our Services, there are terms or settings that narrow the scope of our use of the content submitted in those Services.
You try and find a service with a more limited data grab. Good luck finding it.
Google is IMHO evil - it just talks nice. It learned that trick from Microsoft, but in my opinion even Microsoft never dared venture where Google walks in with hobnailed boots. Beware.
