Heart Rate Recovery
All data gathered by the app is stored on your iPhone. The app only reads your current heart rate from the Health app on your iPhone. We never send any data from the app over a network. Your data is yours, we never see it. We gather no personally identifiable information, or any information for that matter.
If you’ve chosen to share bug reports with developers, Apple can send us technical information regarding crashes of the app. These do not contain any personally identifiable information. If you choose to backup your iPhone to iCloud, your heart rate recovery history will be backed up as well. Again, we do not have access to this information.
