The Financial Times dug into the new iOS developer agreement to find new wording, including a clause that says developers may "not sell an end-user's health information collected through the HealthKit API to advertising platforms, data brokers or information resellers." Also, developers agree not to use the data they collect "for any purpose other than providing health and/or fitness services."
“HealthKit is aggregating data from what will likely be multiple sources within one location on the device,” Geoff Blaber, an analyst at CCS Insight, told FT. "Apple is being very careful as to how that is utilized or controlled. It's Apple tightening control on developers."
Apple has met with officials at the U.S. Food and Drug Administration to discuss regulatory concerns, and reports have surfaced that the company is in talks with medical record firms, insurance companies and other healthcare providers about greater integration of information into the Apple system.
