 We value your privacy and are committed to protecting your personal data. This Privacy Policy explains how we collect, use, store, and protect your information when you use HeartLog, as well as the rights you have regarding your personal information.

Please read this Privacy Policy carefully before using the App. By using HeartLog, you agree to the terms described in this policy.

1. Information We Collect

HeartLog collects data only to the extent necessary to provide core features. We do not collect any information unrelated to app functionality.

1. Information You Provide Voluntarily

  - Health Data: Blood pressure records you manually enter and heart rate data measured through the app.

  - Usage Data: App settings and user preferences.

2. Automatically Collected Information (Non-Personal Data)

  - Device Information: Device model, operating system version, and app version.

  - Usage Statistics: Anonymous data (such as feature usage frequency) to help improve user experience.

We do not collect, store, or transmit any personally identifiable information (such as your name, email address, or phone number), unless you voluntarily provide it in specific cases.

2. How We Use Information

We use the collected information solely for the following legitimate purposes:

1. To provide core features: such as heart rate measurement, blood pressure tracking, and health trend analysis.

2. To improve user experience: enhancing app performance, stability, and usability.

3. To conduct data analysis: understanding user behavior to optimize app features.

3. Data Storage and Security

1. Local Storage:

 Your health data (e.g., heart rate and blood pressure records) is stored locally on your device and is not uploaded to any server.

2. Data Security:

 We implement appropriate security measures—such as iOS system sandboxing and local encryption—to prevent unauthorized access or data leakage.

3. Data Retention:

 We retain information only for as long as it is needed to provide app functionality. When you uninstall the app or manually delete your data, all related records are permanently removed from your device.

4. Third-Party Services

HeartLog does not sell, rent, or share your personal data with any third parties.

 In some cases, we may use third-party analytics tools (such as Apple’s anonymous analytics services) to improve app performance.

 These services only receive anonymized or aggregated data and cannot identify you personally.

5. Your Rights

You have full control over your data within the app:

1. Right of Access: You can view your health records at any time.

2. Right to Rectification and Deletion: You can modify or delete your data whenever you wish.

3. Right to Withdraw Consent: You can withdraw data usage consent by uninstalling the app.

6. Disclaimer

HeartLog is not a medical device.

 All measurements and data records are for personal health management and reference only,

 and should not be used as a substitute for professional medical diagnosis or treatment.

 If you notice abnormal readings or experience any discomfort, please consult a qualified healthcare professional.

7. Policy Updates

We may update this Privacy Policy from time to time to reflect changes in laws, technologies, or business practices.
