They probably don’t. The fake email may be the one that strike gets, but primal (likely) would possibly have access to the email, etc that was linked to your payment method.
Worth noting that Primal claims to not be gathering any other user metrics (in App Store version) which I don’t doubt at all, but using the Apple Pay feature (which is conducted by Apple and not Primal) may cause data to come into their possession.
Primal may wish to have their lawyers look at their Privacy Policy at
as well, as it does not account for information that may be collected or revealed to Primal by Apple Pay. IANAL, but offering friendly feedback.
But on a cursory look through the iOS codebase, I haven’t seen anything concerning or intentional looking. A swift/iOS expert should feel free to correct me, but I’ve been looking at code for a lot of years, and this is my read of it.
