You just don’t buy sats directly inside the app. It’s a normal lightning wallet, so you can send sats from your other Ln wallets. As mail address you can make a completely new one that’s isn’t linked in any way to you. Then there is no obvious way for Apple to know your npub. If there is a way, then the same applies to Damus

I actually used the Hide My Email feature of Apple. This should be encrypted, but obviously there is a chance that Apple holds a key for decryption. But I am not that paranoid.

I was just going through the code looking at this. I don’t see why your npub would be disclosed to Apple from what I’m seeing. But, it might reveal your information to Primal and/or Strike. “Paying with Apple Pay Information Shared When You Make a Payment When you begin a payment within an app, on the web, or within Apple Messages for Business using Apple Pay, to enable tax and shipping cost calculation your zip code, postal code, or other equivalent information is provided to the app, website, or merchant. After you authorize the payment, other information requested by the merchant, such as a device- or merchant-specific account number, your shipping address, or email address, is also provided. The card number from your credit, debit, or prepaid card is not provided when you use Apple Pay.”
