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, and appearance settings.

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, analysis features, data export, 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 share your glucose readings, Apple Health data, diabetes profile, notes, medication details, meal details, or other health-sensitive content for third-party advertising, cross-app tracking, or data brokerage.

Advertising Measurement

DiaNotes may use Meta App Events to measure the performance of DiaNotes advertising campaigns and understand whether ads lead to app installs, app opens, or registration.

• DiaNotes does not send blood glucose values, Apple Health records, diabetes type, medication information, meal details, personal notes, or journal content to Meta.
• DiaNotes disables advertiser ID collection unless tracking is explicitly enabled in a future version and the required iOS permission and App Store privacy disclosures are in place.
• Meta may process basic app event and device information according to Meta's business tools terms and privacy disclosures.

Your Choices and Rights

• All 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 Profile > Account & Security > Delete Account.
