Apple announced HealthKit today at WWDC. This was rumored to be coming so no surprise there, but their description leaves out one critical bit of information. See if you can spot it.
HealthKit allows apps that provide health and fitness services to share their data with the new Health app and with each other. A user’s health information is stored in a centralized and secure location and the user decides which data should be shared with your app.
I’m glad the information is stored securely and the user has control over what is shared with targeted apps, but it says nothing about what is shared with Apple. Woops! If I’ve said it once I’ve said it a thousand times, companies need to be clear about these things up front. Expect to see more information from Apple in the coming days, but also expect bloggers and other media to zoom in on this missing piece of information.
