Plus is sold through Stripe-hosted web checkout where it is enabled, or through the Apple App Store and Google Play products once they are live. The payment provider shows localized pricing, tax, and renewal terms at purchase.
Payment stays with the provider
Card details are entered on the payment provider's hosted page; BaubleStash never stores them and never grants Plus from browser state. The plan shown in your account always comes from the server-authoritative record.
If Plus expires
Owned records are not deleted immediately. Private cloud photos follow the documented retention and warning process. The final deletion policy still requires launch approval.
