An internal Apple presentation now made public by the Department of Justice shows just what the company thought of privacy on Android.
Apple has very explicitly stated in very clear terms that the health app does not share data with other apps or devices unless you give permission. And as someone who has given that permission (twice, once to give a meal tracker write permission and once to link to my doctors office’s application for read and write) it’s for every application. It’s not a “hey you need to let everyone have access or no one”. You can get fairly granular.
There’s always the possibility of lying but usually when a company goes that hard on saying the same thing is so many different ways it’s legit. They don’t commit like that unless they know they won’t get in trouble. Those kinds of statements could open them to false advertising claims if it got out they were taking your health data.
Here’s a link to their privacy document which reviewed a good bit of info: https://www.apple.com/privacy/docs/Health_Privacy_White_Paper_May_2023.pdf
I'll stand corrected on my original comment then. I hope that with Google being dragged through the courts at the moment, perhaps it may inspire more interest and conversation about how our data is handled and how it pertains to the implications around privacy.
