Privacy Policy

Last updated: November 12, 2026

Glucose Blood (the “App”) is provided by the developer identified on its App Store listing (“we,” “us,” or “our”). This Privacy Policy explains how information is handled when you use the App and this website. If you have questions, email support@glucose-blood.com.

1. Information you choose to record

The App allows you to enter an optional name and date of birth, blood glucose measurements, target ranges, weight, systolic and diastolic blood pressure, optional pulse, insulin and medication details, meals or activity information, notes, dates, times, tags, and reminder settings. These records can include sensitive health information. Please enter only information you want to maintain in your personal log.

2. How your health records are used

Information you enter is used to display your journal and history, summaries, estimated HbA1c, reminders, and reports. Glucose readings are normalized internally to mg/dL, while weight readings are stored in kilograms and displayed according to your selected units. Calculations are informational and are not clinical diagnoses.

3. Apple Health

At your request, with the permissions you grant and where required an active Premium subscription, the current App version can read selected blood glucose, weight, and paired blood-pressure samples from Apple Health for import into its local records. The current version does not write data back to Apple Health or perform background Health imports. Imported records can be removed from the App without changing their originals in Apple Health. Apple manages Health data permissions in iOS.

4. Local storage and retention

The current App stores your profile, records, medication information, reminders, and import bookkeeping in an on-device SwiftData database within its app sandbox. It does not require a Glucose Blood account and the current project does not include a cloud account service for uploading health records. Your device's operating-system backups may include local app data according to your Apple backup settings.

Individual records can be deleted in the App. The “Delete Data” option in Settings removes app-managed local records, profile data, reminders, and Health import bookkeeping, and cancels pending app-managed reminder notifications. It does not delete Apple Health records, cancel a paid subscription, or erase technical or purchase records retained by third-party providers.

5. Technical data, analytics, and attribution

Glucose Blood uses Google Analytics for Firebase for app usage and purchase analytics, and Skarb for subscription processing and installation attribution. These services may process device information, technical identifiers, app activity, diagnostics, attribution information, and purchase metadata as needed for their purposes. App analytics events are not designed to include your glucose measurements, medication names, notes, or Apple Health samples.

These providers operate under their own privacy policies and may process information in countries other than your own.

6. Subscriptions and billing

Subscriptions are purchased and managed through Apple's StoreKit and App Store services. The App may receive purchase and entitlement status needed to determine access to Premium features. We do not receive your payment-card details through the App.

7. Device permissions and sharing

Apple Health access and notifications are controlled by device permissions. You can adjust permissions through iOS Settings and the Health app. Your PDF reports leave the App only if you explicitly share or export them using available iOS sharing controls. The recipient and destination you choose may then process the information according to their own policies.

8. Disclosures and service providers

We do not sell your locally recorded health measurements. We may use service providers described above to operate the App, process subscriptions, diagnose technical issues, or comply with lawful obligations. We do not intentionally send your recorded health values or Apple Health samples as app-analytics event parameters.

9. Security

Local app records are stored within the iOS app sandbox. Use your device security and backup settings to protect them. No storage or transmission method can be guaranteed to be perfectly secure.

10. Your choices and requests

You can edit or delete app-managed records, change applicable device permissions, and manage or cancel subscriptions through Apple. To ask about analytics information or other privacy rights applicable to you, contact support@glucose-blood.com. A request about locally stored data may require action on your own device.

11. Children

the App is not intended for children under 13, and we do not knowingly collect personal information from children under 13 through our services. If you record information about a child or dependent, ensure you have appropriate legal authority to manage their information and comply with applicable laws. The App is not a substitute for medical supervision.

12. International processing

Analytics, attribution, subscription, and related technical information processed by third-party service providers may be transferred to and handled in countries other than your own, where data-protection laws may differ. Your locally stored health journal is not intentionally transmitted as part of our analytics event parameters.

13. Changes to this policy

We may revise this Policy to reflect changes in the App, applicable law, or service providers. The date at the top indicates the latest revision.

14. Contact
