You're responsible for your data.
" Google claims no ownership or control over any of your Data. You retain copyright and any other rights you already hold in the Data, and you are responsible for protecting those rights, as appropriate."

I'm being deliberately paranoid here, but past experience with licensing and other legal matters has taught me to assume that contracts mean exactly, and only, what's written. I'd be interested in hearing from anyone who actually is a lawyer about whether my "aggregate, record, and use" scenario could be defended.
