Missing code: check spam and email spelling, wait a few minutes, and retry. Sync: remain signed in and online, check Settings, and retry manually. AI: confirm sign-in and consent; the app uses the local coach on quota or service failure. Purchases: use the same Apple ID and Restore Purchases; cancel from Apple ID subscription settings.
Provide app version, iPhone/iOS, language, issue time, network state, and reproduction steps. Never send verification codes, session tokens, full AI chats, receipts, or sensitive health data; redact screenshots first.
Export or delete the cloud account in-app and clear local data separately. Account deletion does not cancel an Apple subscription. Details: https://breathefree.corrin.cc/delete-account.
Support is not an emergency or crisis service. For chest pain, severe breathing difficulty, or self-harm risk, contact local emergency or crisis services now.
