The social-media giant has been collecting personal information from popular third-party smartphone apps—including Instant Heart Rate: HR Monitor, Flo Period & Ovulation Tracker and Realtor.com—seconds after users enter it, even if the app in use hasn’t been connected to Facebook. The apps often send the data without clear or specific disclosure, according to The Wall Street Journal’s testing. (Wall Street Journal)

Talking point: Though it’s already known that many apps send some user information to Facebook, this latest news shows the extent to which the tech giant has access to sensitive data. Varied across the apps, information includes menstrual-cycle data, heart rates, pregnancy statuses and house-listing prices. The issue comes from a Facebook-made analytics tool that  allows developers to see users’ activity statistics so that the tech giant can then target users with Facebook ads. Apple and Google, which own the two main app stores, don’t require apps to disclose who they share data with.
