You know how many vendors want us to leave email addresses when we buy online? Well, Google knows all about that. It says it doesn’t do anything with the data.

That data is then used to help Google target ads, a division of its business that’s largely responsible for it becoming one of the most valuable corporations on Earth.” – The Verge
