Heart Tracker Launcher

Privacy Policy

Last updated: July 15, 2026

1. Introduction

This Privacy Policy explains how information is handled when you use Heart Tracker Launcher (the “App”) or visit this website. The App provides tools for heart-rate checks and personal health records. It is intended for general wellness and personal reference, not medical diagnosis or emergency use.

2. Information We Collect

Depending on the features you use, the App may process information you enter, such as heart-rate readings, blood-pressure records, dates, times, and notes. It may also receive technical information from your device and information generated through advertising or analytics services. The exact data available can vary by device, operating system, App version, permissions, and service configuration.

3. How We Use Information

Information may be used to operate App features, display and organize your records, maintain reliability, understand feature performance, troubleshoot errors, prevent abuse, and improve the App. Where advertising is present, information may also support ad delivery and measurement.

4. App Usage Data

The App or its service providers may record interactions such as screens viewed, features used, session timing, crashes, and general engagement events. This helps identify technical problems and understand how the App is used. Usage records are not treated as medical advice or a clinical health record.

5. Device and Technical Information

Technical data may include device model, operating system and version, language, region, network type, IP address, App version, diagnostic events, and device or other identifiers. If a feature requests a device permission, the system permission prompt will describe the relevant access. You can manage permissions in your device settings.

6. Advertising and Analytics

The App may use advertising and analytics services. Advertising partners may collect or receive device information, advertising identifiers, approximate location derived from network information, ad impressions, clicks, and App usage data. This information may be used to show ads, limit how often an ad appears, measure campaign results, detect invalid activity or fraud, and improve advertising and related services. Partner practices and available controls may differ by country and device.

7. Third-Party Services

Some functions rely on third-party platforms, including the Galaxy Store, operating-system services, advertising networks, analytics providers, and crash-reporting tools. These services operate under their own terms and privacy notices. Opening the store listing or another external link takes you to a service we do not control.

8. Data Sharing

Information may be shared with vendors that provide hosting, diagnostics, analytics, advertising, fraud prevention, or other operational support. It may also be disclosed when reasonably necessary to comply with law, respond to valid legal process, protect users or services, investigate misuse, or support a business reorganization. We do not describe disclosures by third-party partners as if they were under our sole control.

9. Data Retention

Retention depends on the type of information, where it is stored, operational needs, legal requirements, and the policies of relevant service providers. Records kept locally may remain until you delete them, clear App data, or uninstall the App. Technical, advertising, and analytics data may be retained for periods set by the relevant provider.

10. Security

Reasonable administrative and technical measures are used to protect information handled through the App and website. No device, transmission method, or storage system can be guaranteed to be completely secure. Keep your device protected and avoid entering information you do not want stored in the App.

11. International Users

Heart Tracker Launcher is available to users in multiple countries. Service providers may process information in locations outside your home country, where privacy laws may differ. Applicable safeguards and rights depend on your location and the service involved.

12. Your Choices

You can control App permissions through device settings, reset or limit the use of an advertising identifier where your device provides that option, and stop further App activity by uninstalling it. You may be able to delete locally stored records within the App or by clearing its data. For questions about a request relating to information handled by us, contact the address below. Some information controlled by a third-party provider must be managed through that provider.

13. Changes to This Policy

This policy may be updated when the App, service providers, or legal requirements change. The “Last updated” date shows when this version took effect. Material changes may also be communicated through the App or store listing when appropriate.
