Private by design
Health readings are read from Apple Health and processed on your iPhone. Averages, streaks and your HRV target stay on the device and are not uploaded to us, to our account service or to our iCloud storage. Apple Health remains the source of your readings. An account is optional. Health readings are never included in our online backups.
