Scary story about Google and how much the company knows about you. Adam Clark Estes:
After four years of negotiations, Google purchases a trove of credit card transaction data from Mastercard, allegedly for “millions of dollars.” Google then reportedly used that data to provide select advertisers with a tool called “store sales measurement” that the company quietly announced in a blog post last year, though it failed to mention the inclusion of Mastercard data in the workflow.
What? Google withheld notification of private information it uses against their users?
Thanks in part to heavy government regulation, your credit card and banking data has long been private. If you wanted to spend $98 at Sephora on a Tuesday afternoon, that transaction was between you, your bank, and Sephora. It now appears that Google has found a way to weasel its way into the data pipeline that connects consumers and their purchases. If you clicked on a Sephora ad while logged in to Google in the past year and then bought stuff at Sephora with a Mastercard in the past year, there’s a chance Google knows about that, at least on some level, and uses that data help its advertisers stuff their coffers.
