MasterCard Will Scrub It
If the Apple Card has a weak spot when it comes to privacy, it’s the fact that Apple’s card network partner is MasterCard. Most card networks do share customer information with third-parties. In MasterCard’s case, the company reportedly has an agreement with Google to share data.
Apple, for its part, doesn’t mention MasterCard’s privacy policies on its site. But MasterCard itself said it only shares anonymized and aggregated user data, meaning that an individual purchase shouldn’t be linked back to you. It isn’t a perfect solution, but it’s there.
