Can we share the scale among family members but keep each person’s measurements private?

Yes, absolutely!

Two things need to do to keep everyone’s data private. First, each individual needs to download Arboleaf app to one’s own phone and create one’s own Arboleaf account. Second, when weighing you need to open the Arboleaf app on the “Measurements” screen, so your measurements will be directly sent to your account. In this case your data will not be saved in the scale, others won’t see your results.
