Apple Store app will now recommend Apple products based on your purchasing history
If it bothers you that Apple has the name, model number and part number of your Apple purchases linked to the Apple ID associated with the app, you can disable the feature. Apple has built other new capabilities into version 4.0 of the Apple Store app. You can now more easily discover when your local Apple Store is holding workshops or other events. And you will be told when an order you placed through the Apple Store is ready for pickup.
While visiting an Apple Store, the updated app will now allow you to scan a product to learn more about it. And when you walk into a brick and mortar Apple Store, the app will let you know if that particular location has any inventory remaining of Apple products you've flagged as a favorite. The goal for Apple is to get you to spend more money on accessories for your Apple devices.
