Introduction
Wuhan Newrathon Technology Co., Ltd. ("we," "our," or "us") operates the MultiHR application (the "App"). This Privacy Policy explains how we collect, use, and protect data when you use the App.
Important Notice
MultiHR is designed for scientific research, device validation, and sports science workflows. It is not intended for medical diagnosis.
Information Collection and Use
Personal Data
While using the App, we may process information such as:
- Bluetooth device information
- Heart rate data from connected devices
Technical Data
We may collect technical information such as:
- Device model and operating system version
- App performance data
- Crash reports
System Permission Usage
On HarmonyOS, MultiHR requests the following user-grant system permission:
- ACCESS_BLUETOOTH (ohos.permission.ACCESS_BLUETOOTH): used to scan for, identify, and connect nearby Bluetooth heart-rate devices, and to receive heart rate, RR interval, battery, and device information data provided by currently connected devices. This permission is used only for Bluetooth heart-rate monitoring and recording, and is not used for location tracking, contacts access, audio recording, camera access, or scanning unrelated devices. If you deny this permission, MultiHR cannot search for or connect to Bluetooth heart-rate devices.
Data Storage
- Heart rate data is stored locally on your device.
- No heart rate data is transmitted to our servers unless you explicitly export it.
- Once exported from the device, further handling of the file is your responsibility.
Use of Data
Collected data may be used for:
- Providing and maintaining the App
- Improving stability and usability
- Technical support
- App analytics
Data Security
We use reasonable technical and organizational measures to protect your data. No internet transmission or electronic storage method is completely secure, so absolute security cannot be guaranteed.
Third-Party Services
The App integrates with third-party services like RevenueCat to facilitate in-app purchases and subscription management. RevenueCat may collect information including device identifiers and transaction history to complete these orders. Their privacy practices are governed by their own policies.
Children's Privacy
The App is not intended for children under 13 years of age, and we do not knowingly collect personal information from children under 13.
Your Rights
- Access your personal data
- Correct inaccurate data
- Request deletion of your data
- Export your data
- Withdraw consent where applicable
Data Retention
Personal data is retained only as long as necessary for the purposes described in this policy.
Changes to This Privacy Policy
We may update this Privacy Policy from time to time. Changes become effective when the new version is posted on this page.
