Privacy Policy

What We Collect

• Blood glucose readings, timestamps, meal context, notes, and source labels for entries you create or import.
• 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

• Authenticate your account and keep your data available after sign-in.
• Store and display your glucose history across supported devices.
• Support Apple Health import and export when you explicitly grant permission.
• Provide reminders, premium 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.

Retention and International Processing

• DiaNotes-stored account data, profile details, and glucose records are generally retained until you delete your account, unless a longer retention period is required by law.
• Because DiaNotes relies on cloud providers such as Firebase, data may be processed in countries other than your own, subject to provider safeguards and security controls.

Apple Health and HealthKit

Apple Health access is optional. DiaNotes only reads or writes Blood Glucose samples after you grant permission in Apple Health.

• Imported HealthKit readings keep their original source label.
• Imported HealthKit readings are read-only inside DiaNotes.
• You can revoke Apple Health access at any time in the Health app under Sharing and Apps.

Data Sharing

• DiaNotes does not sell or rent your personal data or health data.
• We share data only with service providers needed to operate DiaNotes, such as Apple platform services and Firebase infrastructure.
• We do not use your data for third-party advertising, cross-app tracking, or data brokerage.

Your Choices and Rights

• Premium users can export glucose history in Settings > Data & Privacy > Export Data.
• If you need a copy of your DiaNotes-stored data for a privacy or access request, contact privacy@diaeats.net.
• You can delete your DiaNotes account and DiaNotes-stored data in Settings > Data & Privacy > Delete Account.
• If you delete your account, any Apple subscription remains billed by Apple until it is canceled in your Apple subscriptions settings.
