MoodWatcher is a single-user research project. It collects health and mood data only from the owner of this device, and stores it exclusively in that user's personal iCloud Documents container.
When the user connects their Withings account, MoodWatcher requests the minimum scopes needed for mood prediction (heart-rate variability, sleep, activity, and ECG events). The OAuth refresh token is stored in the iOS Keychain on-device. The user may revoke access at any time from their Withings account settings.
