How does Huawei Health check the weight records of visitors?

Can't check. Huawei Health can take the visitor mode. You only need to input the data such as the gender, height and age of the visitor, and you can measure it. The data is not stored, so it is impossible to query the visitor's weight record. Huawei Health is an open sports health data service provided by Huawei and an open sports health ecological data platform.
