It is not just Android Google but Google. You can download what they have stored and request they delete it. You can also select what they store and what they don't.
It is not hard to escape from the information Google keeps on you. The biggest problem is lemmings just accepting the T's&C's without realising the permissions they give.
Here's a good place to start if you want to take back control.

It may actually open your eyes on what you have allowed Google to collect. Don't forget you accepted the T's&C's and accepted them without reading. Had you read them you could've opted out.
EDIT If you want to make sure you get everything they have select the 50Mb archive in the dropdown box.
