WaterTracker and Google Health

WaterTracker requests https://www.googleapis.com/auth/googlehealth.nutrition.writeonly solely to write the water intake you record in the app to Google Health after you authorize the connection. WaterTracker does not request a separate Google Health read-only scope for this feature.

Google groups hydration logs under its nutrition permissions. Although the permission is named nutrition.writeonly, WaterTracker uses it for water intake, not food tracking. The permission also allows an app to edit or delete data it adds. WaterTracker supports deleting drinking records that it has written to Google Health.

Your drinking records are stored locally on your device. When you authorize writing them to Google Health, the submitted records are also stored by Google Health. Local storage in WaterTracker and storage in Google Health are separate. Drinking records do not pass through our servers.

WaterTracker stores the OAuth tokens for the Google Health connection on your phone.

Local drinking records are kept until you delete them. You can select the records you want to remove in the app and delete them. WaterTracker also supports deleting records it has written to Google Health. For help with deleting records from Google Health, contact hustapp@foxmail.com.

The purpose of this Google Health permission is the water-intake feature described above. The general advertising, partner-sharing and retention provisions elsewhere in this policy do not apply to your drinking records or Google Health OAuth tokens; their handling is described in this section. For questions about your drinking records or the Google Health connection, contact hustapp@foxmail.com.
