Terms of Use

Service Description

This application is a mobile application for measuring heart rate, recording blood pressure and blood oxygen, and calculating HRV. It provides a convenient way to monitor and record your physiological data to help you understand your health status.

Heart rate measurement is mainly based on your device's sensors and software algorithms, and is for reference only. It can detect your heart rate through optical sensors or other technologies and calculate heart rate variability (HRV) by analyzing the data. Please note, however, that these measurements and calculations may be affected by factors such as environmental conditions, user's physiological state and device performance. Therefore, they are not intended to be a substitute for professional medical equipment and professional medical advice.

This app may provide general reference ranges for heart rate, blood pressure, and blood oxygen levels, but these ranges are for general information only and may not apply to everyone. Everyone's physiology and health needs are different, so you should interpret and evaluate these data in light of your own circumstances and medical advice.

We recommend that you use this application as an auxiliary tool for health monitoring and recording, rather than the sole basis for medical diagnosis or health decision-making. If you have any medical questions or concerns, or require an accurate medical diagnosis, please consult a medical professional.

You should maintain an appropriate mental and physical state when using this application, and follow the measurement guidelines and instructions for use. Please avoid using the app while exercising, as movement may interfere with the measurement results. If you feel unwell or experience any unusual symptoms, please stop using this app and seek medical attention.

This application may provide data storage and synchronization functions so that you can track and manage your physiological data. Please note that you are responsible for the backup and protection of your own data. We recommend that you regularly back up your data and take necessary security measures to prevent unauthorized access or data loss.

You understand and agree that due to technical limitations and unforeseen factors, the application may experience interruptions, malfunctions or errors. While we will do our best to ensure the proper functioning and data accuracy of the App, we cannot guarantee that it will always be available, completely secure, or error-free. When using this app, you do so at your own risk.

We reserve the right to modify these Terms at any time and will notify you by sending you a notice or posting the revised terms on this app. Your continued use of this application will be deemed to be your acceptance of the revised terms. Therefore, please review the Terms periodically for the most up-to-date terms.
