Cloud backup is disabled by default. If you explicitly enable it:

• You control which data to sync
• All data is encrypted before upload
• You can disable sync at any time

5. Data Sharing and Disclosure

We do not sell, rent, or share your personal health data with third parties.

Limited data sharing may occur only:

• Within your family group: If you explicitly invite family members, they can view shared records you authorize
• With your explicit consent: When you use "Share Report" to export PDF/Excel files
