Privacy
Your streak, journal, unsent letters and check-ins stay on your iPhone. Heal has no account and no sign-up, doesn't sync your entries to a cloud, shows no ads, and has no sharing features: your milestones and medals are for you alone. You can lock Heal with Face ID, Touch ID or your passcode; iOS handles the check, and Heal never receives your face or fingerprint data. Purchases go through Apple, and a purchase service (RevenueCat) checks whether you have Heal Premium; that purchase data isn't linked to your identity.
