Not everyone is aware of this.
There are people who believe that buying on the Internet is private and no, it is far from real, if you do not take precautions that probably almost no one does.
Today, CNBC revived this issue and the reaction of people's concerns has been huge, so much that it is replicated by high-speed networks right now.
It's so easy to be in your account and click here, where you can see everything Google knows about your online shopping habits thanks to Gmail.
You should see something like this if you usually buy online:
There you can see all your shopping history and Google explains that "it does not use this information for commercial purposes and that you can only see it yourself", but on the other hand contradicts by confirming that this data is shared with the other Google the applications, We conclude that, and as the company said so many times, "give you a more personal experience".
The only way to eliminate this story is to eliminate all purchases from the list one by one, yes, something quite boring and that clearly shows that Google does not want you to erase anything.
They say personal data is the oil of this century, perhaps they are not so much wrong.
