Apple has updated their HealthKit privacy policy for developers in order to keep user data from falling into the hands of advertisers and data brokers.
TNW:
The Financial Times reports that the company’s updated policy will stop third-party apps from using personal data collected while using the HealthKit platform for anything other than informing users of their health.
HealthKit, a part of the upcoming iOS 8 launch, acts as a central hub that collects data from third-party apps and accessories, that info is then processed and presented in the iOS 8 Health app, via easy to follow graphs and charts.
