Got several notices to this article in the Washington Post about some new features Google is flaunting to it’s customers: Google now knows when its users go to the store and buy stuff. Somehow Google has got it hands on creditcard data to tell them when you buy stuff. Almost the same as Uber got your receipts from Lyft provided by Unroll.me. I wonder where it will end, who is selling your data without you consent. Or is asking for your consent hidden in an EULA that is to long to read.
Just to make sure you know: You are not a Google customer unless you give them money and as far as I can tell the only people that do that are advertisers.
I myself try to limit my exposure to Google and their all seeing eye. Happy to just pay for my Apple products that make me the customer and give me more rights and privacy.
