This looks like a challenge:
So I'm going to write to google and see what they say.
I'll be making the application under the Irish Data Protection Acts as described here:
Just in case anyone thinks I'm doing this to annoy Google - I'm not. It's just a simple test. The result is going to be (a) Google were really nice and did exactly what I asked of them in a friendly way or (b) Google laugh me out of their office and get me to sue.
The person I have to write to is Graham Law (http://www.google.ie/intl/en/contact/index.html) who doesn't have an e-mail address, so I have to use the old snail mail.
Dear Mr Law,
I want to make a request for my personal information under the Data Protection Act can you tell me what information you require in order to complete this request and what fee you charge for this.
