Restore
Restore Purchases requests current App Store entitlements and revalidates each active CruiserFM product.
SUBSCRIPTION HELP
Apple bills it. CruiserFM verifies it.
Purchases use StoreKit 2. The app sends Apple's cryptographically signed transaction to CruiserFM's validation service, which returns only the radio radius and hosting limit included in the active product.
Renewal and expiry
App Store Server Notifications update access after renewal, billing failure, grace-period expiry, refund, or revocation.
Short cache
Successful entitlements are cached only until shortly after Apple's reported expiry. Radio access tokens expire within minutes.
