Not everyone is aware of this.
There are people who believe that purchases made on the Internet are private and not, it is far from reality unless you take precautions that probably almost nobody does.
Today, CNBC has revived this issue, and the response to people's concerns has been enormous, so much that it is being reproduced at high speed networks at this time.
It's as simple as getting into your account and clicking here where you can see everything Google knows about your shopping habits online thanks to Gmail.

Here you can see your entire shopping history and Google declares that "it does not use this information for commercial purposes and that you can only see it", but on the other hand, they contradict each other by recognizing that this data is shared with others Google apps, We conclude that, and as the company has said so many times, "gives you more personalized experience."
The only way to eliminate this story is to eliminate all purchases from the list one at a time, yes, something pretty annoying, and that clearly shows that Google does not want to delete anything.
They say that personal data is oil of this century, maybe not very wrong.
