The social networking giant, "Facebook" has partnered with many retailers to collect customer data and provide it to Facebook, who will find customer profiles on the site and target them with specific ads for those stores.
The information that stores provide to Facebook includes the customer’s name on the payment card, personal e-mail, birth date and phone number in some cases, and things he has purchased so that the advertising process is more specific, and Facebook cannot track customers in operations Purchasing without cards.
However, users can unsubscribe from the process that allows their data to be shared with Facebook through stores by selecting "Ads" in "Facebook Settings" and choosing "Not Allowed" under "Advertisements based on data from partners".
