Millions of smartphone users confess their most intimate secrets to apps, including when they want to work on their belly fat or the price of the house they checked out last weekend. Other apps know users' body weight, blood pressure, menstrual cycles or pregnancy status.
Unbeknown to most people, in many cases that data is being shared with someone else: Facebook Inc.
Apple Inc. and Alphabet Inc.'s Google, which operate the two dominant app stores, don't require apps to disclose all the partners with whom data is shared. Users can decide not to grant permission for an app to access certain types of information, such as their contacts or locations. But these permissions generally don't apply to the information users supply directly to apps, which is sometimes the most personal.
In the Journal's testing, Instant Heart Rate: HR Monitor, the most popular heart-rate app on Apple's iOS, made by California-based Azumio Inc., sent a user's heart rate to Facebook immediately after it was recorded.
Flo Health Inc.'s Flo Period & Ovulation Tracker, which claims 25 million active users, told Facebook when a user was having her period or informed the app of an intention to get pregnant, the tests showed.
The Journal's testing, however, showed sensitive information was sent with a unique advertising identifier that can be matched to a device or profile. A Flo spokeswoman subsequently said the company will "substantially limit" its use of external analytics systems while it conducts a privacy audit.
Move, the owner of real-estate app Realtor.com—which sent information to Facebook about properties that users liked, according to the Journal's tests—said "we strictly adhere to all local, state and federal requirements," and that its privacy policy "clearly states how user information is collected and shared." The policy says the app collects a variety of information, including content in which users are interested, and may share it with third parties. It doesn't mention Facebook.
