[spoiler]It uses bluetooth for one. So only the device you connect to it can get the data. After that it all depends on you and which mobile operating system your phone has. iOS (Apple) encrypts in and nobody but you will be reading it.

As ugh responded their own app can basically do whatever they feel like. If they just used (for iOS) the Health app it might be safer. I don’t know if any of these scales do or can do so directly. I’m interested to know if they can. Or at least if whatever scale’s app didn’t ask for any registration and just forwarded the data through the Health API, it would be alright.
Though might as well manually fill in your weight in the Apple Health app in this case… it hardly saves you any time of your life.
