Not everyone is aware of this.
There are people who believe that purchases made on the internet are personal and not, that are far from reality, unless you take precautionary measures that may not be carried out by anyone.
Today CNBC is reviving this problem and the reaction of people's concerns has been extraordinary, such that it is being replicated by today's high-speed networks.
It's as easy as being in your account and clicking here, where you can see everything Google knows about your online shopping habits, thanks to Gmail.
You will see something like that, if you usually buy online:
There you can see all your shopping history and Google states that "it does not use this information for commercial purposes and that you can only see it for yourself", but on the other hand, they contradict that this data is shared with other Google applications, We conclude that, and as the company often says, "gives you a more personal experience".
The only way to get rid of this history is to eliminate all purchases from the list one by one, yes, something that is quite boring and that clearly shows that Google doesn't want you to delete anything.
They say that personal data is oil of the century, maybe they are not wrong.
