> What a bizarre paragraph. First it explicitly makes it clear that it's forbidden to send the payment information using contact information obtained via the app. However the last sentence is a generic statement that seems to contradict that. Does Apple mean that you can only use contact information obtained elsewhere? That would then match the previous terms. So it's probably that. However it is worded in such a horrible way that I can't be sure.

That sounds like you can’t use contact info you received as part of a paid signup to contact to switch to an out of band payment method.

In contrast to contacting a free tier user who’s email you’ve received as part of their signup flow. That situation would be allowed.

Indeed it’s bizarre as depending on when the contact data was gathered decides what you can do with it.
