Heart Habits Journal — Privacy Policy

1. Overview

Heart Habits Journal (“the App”) is developed and operated by Aleh Rabchuk (“we”, “us”, or “our”).

Your privacy is important to us. Heart Habits Journal is designed to work without user accounts, advertising, analytics, or developer-operated servers.

Your health information and other app data are stored locally on your device. We do not collect, upload, sell, or share your personal health information.

The App uses Apple Health, when authorized by you, to read and save blood pressure and pulse readings. Apple processes in-app purchases through its own payment system.

2. Information Stored on Your Device

To provide its features, the App stores information locally on your iPhone. This may include:

Blood pressure journal

• Blood pressure readings (systolic and diastolic values).
• Pulse readings.
• Date and time of each reading.
• Optional notes added to your readings.

Plans and reminders

• Selected health and lifestyle methods.
• Planned days, times, and durations.
• Completion and skipped-item history.
• Personal habits created in the App.
• Reminder preferences and schedules.

Medication and supplement schedules

• Names of medicines and supplements you add to your personal schedule.
• Reminder schedules associated with those entries.

The App does not provide medication dosage instructions or recommendations.

Onboarding and preferences

• Your responses to onboarding questions about high blood pressure and blood pressure medication.
• Your selected methods and app preferences.
• Display settings, theme, and other configuration choices.

This information is processed locally to provide the App’s functionality. We do not have access to it.

3. Apple Health Integration

Heart Habits Journal optionally integrates with Apple Health using Apple’s HealthKit framework.

With your permission, the App can:

• Read blood pressure and pulse readings from Apple Health and display them in your journal.
• Save blood pressure and pulse readings entered in the App to Apple Health.

Apple Health access is optional. You can grant or deny the requested permissions and change them at any time through your iPhone’s privacy settings.

Health information accessed through HealthKit is used solely to provide the App’s health and wellness functionality.

We do not:

• Send HealthKit information to our servers.
• Share HealthKit information with analytics or advertising services.
• Use health information for advertising, marketing, or user profiling.
• Sell health information to third parties or data brokers.

Your Apple Health data remains under your control and is managed through Apple’s Health app and iOS permissions.

For more information about how Apple handles health information, please refer to Apple’s Privacy Policy.

4. PDF Reports

The App allows you to generate PDF reports of your blood pressure history for personal use or to share with a healthcare professional.

Reports are generated locally on your device and may contain:

• Blood pressure and pulse readings.
• Dates and times of readings.
• The selected reporting period.
• An optional name entered for the report.

The App does not upload or store generated reports on our servers.

If you choose to share, save, email, or otherwise export a report, the information will be handled by the destination app or service you select. Their privacy practices and terms will apply.

5. Notifications

The App can schedule local notifications on your device for habits, activities, medication and supplement reminders, and blood pressure measurements.

Notifications are generated and delivered by iOS. The App does not use a push-notification server.

You can disable notifications or change their permissions at any time in your iPhone settings.

By default, medication names are not displayed on the Lock Screen.

6. Research Sources and External Websites

The App includes links to scientific publications and other research sources referenced in its method library.

When you open a link, the corresponding website is loaded in an in-app browser. The external website may receive standard technical information, such as your IP address and browser or device information, as part of a normal website connection.

We do not transmit your blood pressure readings, journal entries, or other personal health information to these websites.

External websites operate independently and have their own privacy policies. We are not responsible for their privacy practices or content.

7. In-App Purchases

Heart Habits Journal offers optional purchases through Apple’s StoreKit system:

• Plus Monthly — an automatically renewing monthly subscription.
• Plus Yearly — an automatically renewing annual subscription, which may include a free trial for eligible new subscribers.
• Plus Lifetime — a one-time purchase.

All payments are processed by Apple through your Apple Account.

We do not receive or store your payment card details, billing address, or Apple Account password.

The App receives the transaction information necessary to verify purchases and provide access to Plus features. A local record of Plus activation and subscription expiration is stored on your device.

Apple is responsible for processing payments, subscription renewals, refunds, and purchase records in accordance with its own policies.

For information about Apple’s data practices, please see Apple’s Privacy Policy.

8. Data Collection and Third-Party Services

Heart Habits Journal does not use:

• User accounts or registration.
• Advertising networks.
• Third-party analytics or tracking services.
• Third-party advertising SDKs.
• Developer-operated servers or cloud databases.
• Location tracking.

We do not collect app usage statistics or transmit personal health information to external services.

The App may communicate with Apple services to process and restore purchases and with external research websites when you choose to open a source link.

The App does not sell or rent personal information.

9. Email and Support Requests

The App includes options to suggest a research source or report a problem.

These options open your device’s email application with a prepared message. The App does not send emails automatically.

If you choose to send the message, the information you include will be transmitted through your email provider to us. Such correspondence may be retained in our email system for the purpose of responding to your request.

Please avoid including unnecessary sensitive health information in support emails.

10. Data Storage, Retention, and Deletion

Your App data is stored locally on your iPhone. The App does not offer account-based cloud synchronization.

We do not maintain a server-side copy of your journal, plans, onboarding answers, or settings.

Your locally stored information remains on your device until you delete it using the App’s data deletion feature or remove the App from your device.

Deleting data from the App does not automatically delete:

• Blood pressure and pulse entries previously saved to Apple Health. These can be managed separately in Apple’s Health app.
• PDF reports you previously exported or shared.
• Purchase and subscription records maintained by Apple.
• Emails you have already sent to us.

Apple manages its own purchase and account records under its privacy policies.

11. Security

We use Apple’s built-in iOS security mechanisms and local application storage to help protect information handled by the App.

Because your journal and personal information remain on your device, we recommend keeping iOS up to date and protecting your iPhone with a passcode or biometric authentication.

No method of electronic storage or transmission can guarantee absolute security.

12. Children’s Privacy

Heart Habits Journal is designed for adults aged 18 and older and is not intended for children.

The App does not include account registration or developer-operated data collection from children.

If you believe that a child has sent us personal information through a support email, please contact us so that we can address the matter.

13. Your Privacy Rights

Depending on your place of residence, applicable privacy laws may provide rights concerning your personal information, including rights to access, correct, delete, or restrict certain processing.

Since the App stores its primary data locally and we do not have access to your journal or health records, you can manage and delete this information directly within the App and through Apple Health.

For questions or requests concerning information that we may hold, such as support correspondence, please contact us using the address below.

14. Changes to This Privacy Policy

We may update this Privacy Policy when the App’s features or data practices change.

The latest version will be published on this page, together with its updated date.

We encourage you to review this page periodically.
