Privacy Policy

1. Introduction

HeartBalance (“we,” “our,” or “us”), developed by Axiosware, is a heart-health and fitness app for iOS. This Privacy Policy explains what information the app accesses and collects, how we use it, and the choices you have. By using HeartBalance, you agree to the practices described here.

2. Health & fitness data we access

With your explicit permission, HeartBalance reads health and fitness data from Apple Health (HealthKit). Depending on what you authorize, this may include:

• Heart rate
• Step count
• Active energy burned

You control this access in the iOS Health app and can revoke it at any time. In keeping with Apple’s requirements, health data obtained through HealthKit is never used for advertising or sold to third parties.

3. Camera & on-device measurement

HeartBalance can measure your heart rate using your iPhone’s camera and flash (photoplethysmography). When you take a reading, camera frames are processed on your device to detect blood-flow changes at your fingertip. We do not store, upload, or transmit any photos or video; only the resulting heart-rate value is saved as part of your health history.

4. Account information

You can create an account using Sign in with Apple or Google Sign-In, handled through a trusted third-party authentication provider. When you sign in, we receive a unique user identifier, your email address, and your name if your provider shares it. We use this only to authenticate you and to sync your data across your devices.

5. How your data is stored

On your device

Your measurements and history are stored locally on your device so the app works offline.

In the cloud (when signed in)

When you are signed in, your profile and daily summaries are stored with a trusted third-party cloud provider so they can sync across your devices and power weekly trends. These summaries include your daily step count and step goal, active energy, and heart-rate summary values (latest, average, minimum, and maximum BPM and the day’s readings), as well as your subscription status. If you are not signed in, your data remains on your device.

6. Subscriptions & payments

HeartBalance offers an optional premium subscription. Purchases are processed by Apple through the App Store, and the paywall is managed through a third-party subscription management provider. We do not receive or store your full payment details. Apple handles all billing. We retain a record of whether your subscription is active in order to unlock premium features.

7. Notifications

With your permission, HeartBalance sends daily summary notifications. Push delivery is handled through standard third-party push notification services. You can disable notifications at any time in iOS Settings.

8. Third-party services

We rely on the following service providers:

• Apple: HealthKit, Sign in with Apple, the App Store, and StoreKit for subscriptions.
• Cloud service providers: for account authentication, secure cloud storage and sync, and push notifications.
• A subscription management provider: for operating the subscription paywall and related analytics.

Each provider processes data under its own privacy policy, and we encourage you to review them.

9. How we use your information

• To provide heart-rate measurements, scores, and insights
• To sync your data across your devices
• To generate weekly trends, badges, and coaching tips
• To manage your subscription and unlock premium features
• To send the notifications you’ve enabled
• To maintain, troubleshoot, and improve the app

10. What we do not do

• We do not sell your personal or health data.
• We do not use your health data for advertising.
• We do not store or transmit camera photos or video.

11. Your choices & rights

• Revoke HealthKit, camera, or notification access at any time in iOS Settings or the Health app.
• Permanently delete your account from within the app. This deletes your account and all associated data (your profile, health history, and subscription records) from our servers, and clears your data from the device.
• Request access to or deletion of your data by emailing us at admin@axiosware.com.

12. Data retention

Local heart-rate readings are kept on your device on a rolling basis, and your daily history is retained so you can see long-term trends. Cloud records are retained while your account is active. When you delete your account, your authentication and all cloud records associated with your account are permanently deleted from our servers.

13. Children’s privacy

HeartBalance is a health app intended for adults and is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us so we can remove it.

14. International users

HeartBalance is operated from the United States, and your data may be processed and stored on infrastructure provided by Apple and Google, including servers located in the United States. By using the app, you consent to this processing.

15. Changes to this policy

We may update this Privacy Policy from time to time. We will post the revised version here and update the “Last updated” date above. Your continued use of the app after changes take effect constitutes acceptance of the updated policy.
