Apple has begun using its Health app to collect information on users’ medical conditions, even though privacy concerns are widespread.
Health has long used HealthKit to collect data on Apple users’ activity, but this has become a much more invasive process, said Brian Luskin, an analyst at the research firm Gartner.
Users may have to log into their iPhone to view a medical history, and there are also restrictions on how users can interact with the app.
Apple says HealthKit is now “designed to be as secure as possible.”
Apple does not explain how it decides what information is appropriate for Health, or what specific circumstances require it to collect medical information.
Apple declined to comment for this story.
Luskins said the Health app is the “most intrusive piece of health-related data ever.”
Apple Health requires users to log in to the Health service with their iPhone, then access information from HealthKit.
The app will then automatically log in users to their Health account.
Users can then control the app from the Health Dashboard, which shows information about their health, including health conditions and the apps that they use.
“HealthKit is designed to be a surveillance tool, to gather data about your health,” said Luski.
HealthKit does not provide any information to Apple about the medical information that it collects, which could be used for marketing purposes, he added.
Health said it did not know whether Apple would continue to use HealthKit, which was developed by the company’s Apple-owned XCode unit.
Apple said HealthKit has been approved by Health and Safety and is used in Health apps from Microsoft, Google, Facebook, and others.
Privacy International has said Apple should stop using HealthKit and instead restrict its use to Health Services.
Apple spokeswoman Emily Molloy said Apple is reviewing the privacy policies of Health Services providers.
Apple has been testing a number of ways to collect health information from users, but the company said its Health Services app only collects information from Apple users.
Lusk also said it would be good if Health would consider making HealthKit available to third-party developers.
That app could collect data from users that could be shared with third-parties.
In some cases, third-Party developers could also sell health information to third parties, including hospitals and doctors, Apple said.
“We’re working with third parties to create the best possible Health app, so we can provide a more personal experience to our customers,” Lusinski said.
Apple does use Health Services in Health Services apps, and the company has not yet disclosed the types of health information it collects.
Apple did not immediately respond to a request for comment.
Health Services is not the only app that collects health information.
Google Health, which is used by Google and other companies, has also collected medical information from Android users.
Google declined to say how much information it is collecting from Android.
But privacy concerns have been raised, with privacy advocates alleging that Health Services collects information about Android users without their consent.
Health also does not have an opt-out system.
Apple users can opt out of using Health Services from Health Services and other Health Services, Health said.
