Account data lifecycle

  • Apple subjects, refresh tokens, and account nicknames are encrypted at rest.
  • Apple email and avatar data are not requested or stored.
  • Deleting an account removes its session, profile, referral, grant, and mutable account records in the same local transaction before Apple revocation is retried.
  • Product analytics installations linked to the account and all of their events are deleted by database cascade. The service stores only the digest of a random installation UUID and never stores user content in analytics events.
  • Pseudonymous immutable credit-ledger entries, StoreKit transaction audit data, and time-limited anti-abuse tombstones remain after deletion where required to prevent replay, preserve financial integrity, and stop repeated trial abuse.
  • Logs must never include Apple subjects, credentials, tokens, or nicknames.
