  • Account and profile information such as sign-in email, authentication provider, display name, birth date, diabetes type, height, and weight.
  • Preferences and settings such as glucose unit, target ranges, reminders, appearance settings, and subscription state.

How We Use Your Data

  • Support Apple Health import and export when you explicitly grant permission.
  • Provide settings, reminders, subscription features, and account management.

How We Store Your Data

DiaNotes stores account profiles and glucose records in Firebase services so your data can be retrieved after sign-in. Data is encrypted in transit and protected by provider security controls.
