I hear you, “Kim, her phone listened!” The answer is not so simple, but I can explain what is really going on.
Your digital mark

If you connected with a Wi-Fi store or entered with Bluetooth, Walmart and other merchants can track your movements. They know where you are standing at the store. They also know you didn’t buy knives.
Merchants sell this information to the advertising networks that then work with the data brokerage to get your e -Štust address. Bingo. Linda got an E -stain from a knife company. I bet she also started seeing ads for knives and related items online.
But wait, there are more
Facebook, Instagram, Google and Weather Apps follow your location, even when they are running in the background. If you have approved access to the location, they know where you are, and later use these advertising information.
