A Quick Note on Data Syncing
Ucardia does not pull data directly from your device.
Data flows from your device → Apple Health or Google Health Connect → Ucardia.
If data doesn't appear, check permissions in:
iPhone: Settings → Health → Data Access & Devices
Android: Settings → Health Connect → App permissions
Your data, your control. Ucardia just helps turn it into insight.
