Why does the app need my height, age, and other private information when I first sign in?

The Arboleaf Body Composition Smart Scale uses the Bio-electric Impedance Analysis Method to measure body compositions. The BIA Method needs the input of a user’s gender, age and height. Your body fat, body water and other body compositions are based on such information and the measured body impedance. It is the reason we need you provide your gender, age and height. Without these the scale can only measure your weight.

Your personal information will be kept private. The info will only be used for body composition measurements.
