Connecting and Managing Apple Health Data

Learn how to connect Sunu to Apple Health and manage data permissions at any time.

Background refresh disabled
iOS Health app having issues

Solutions:

Step 1: Verify permissions are enabled

Step 2: Open Apple Health app

Confirm data exists there
Check dates of last entries
Verify source of data

Step 3: Enable background refresh

Settings > Sunu
Enable "Background App Refresh"

Step 4: Restart both apps and iPhone

Duplicate Data

Why it happens:

Multiple sources writing same data
Manual entries plus device entries
Different apps tracking same metrics

How to fix:

Step 1: In Health app, check data sources

Health > Browse > [Metric] > Data Sources & Access

Step 2: Prioritize sources

Drag preferred source to top
This determines which data displays

Step 3: Remove duplicate entries

In Health app, delete unwanted data points
Or hide sources in Sunu

Privacy and Security

What Apple Health Protects

Your data is secure:

Encrypted on device
Requires authentication to access
Not shared with Apple
You control all permissions

What Sunu sees:

Only categories you explicitly allow
Can't access without permission
Can't modify Health app settings
Respects Apple's privacy framework

Revoking Access

To completely disconnect:

Step 1: Settings > Health > Data Access & Devices > Sunu

Step 2: Tap "Delete All Data from Sunu"

Step 3: Confirm deletion

What happens:

Sunu loses all access
Historical data in Sunu preserved
No new data syncs
Must re-grant to reconnect

Managing Multiple Devices

Apple Watch + iPhone

How it works:

Watch syncs to iPhone Health app
Sunu reads from iPhone Health
All data appears in Sunu
Automatic consolidation

Best practices:

Wear Watch consistently
Keep devices paired
Allow background sync
Check both devices charged

Other Health Devices

Compatible devices:

Smart scales (WiFi connected)
Blood pressure monitors
Glucose meters
Fitness trackers

Setup:

Connect device to its own app
That app writes to Apple Health
Sunu reads from Health
Data flows automatically

Data Source Priority

When Multiple Sources Exist

Apple Health handles this:

Prioritizes most recent data
Can set preferred sources
Averages multiple readings
Removes obvious errors

In Sunu:

Displays source for each reading
Shows all data points
Respects Health app priorities
Can filter by source

Best Practices

Keep Permissions Updated

Review regularly:

Check every few months
Add new categories as needed
Remove unused permissions
Ensure optimal functionality

When to review:

After iOS updates
When adding new devices
If features aren't working
When privacy concerns change

Balance Privacy and Functionality

Consider:

More data = better AI insights
Less data = more privacy
Choose what matters to you
Can always adjust later

Recommendations:

Enable essential health metrics
Add categories as you use features
Disable truly unused categories
Write access only where needed

🔒 Privacy Note

Sunu never uploads your raw Apple Health data to servers. The AI analyzes your data locally on your device when possible, and only minimal, aggregated data is sent for complex analysis. You control exactly what Sunu can access through Apple's permission system.

💡 Pro Tip

If you're unsure which permissions to grant, start with "Turn On All" for 2 weeks. Then review the Profile > Data Sources screen to see which categories you actually use. Disable permissions for categories you haven't looked at—you can always re-enable them later.
