When your telephone is locked with a passcode, Touch ID, or Face ID, your whole well being and health knowledge within the Health app, aside from your Medical ID, is encrypted. Any well being knowledge synced to iCloud is encrypted each in transit and on our servers. And when you have a current model of watchOS and iOS with the default two-factor authentication and a passcode, your well being and exercise knowledge might be saved in a method that Apple can’t learn it.
