Facebook Inc. (FB - Get Report) is grappling with another privacy controversy in the wake of revelations that fitness and health apps have been transmitting data about users' weight, menstrual cycles and other sensitive information to the social media company.
Apps including "Flo Health Inc.'s Flo Period & Ovulation Tracker and Azumio Inc.'s Instant Heart Rate: HR Monitor," have taken steps to sever the transmission of sensitive information to Facebook, according to The Wall Street Journal, which first reported the practice in a story on Friday.
Investors so far are taking the latest Facebook privacy scandal in stride. The social media giant's stock was up 1.4% on Monday to $164.17.
Facebook stock has rallied over the past month after hitting $144.19 on Jan. 29.
The Journal tested 70 popular apps offered on Apple's iOS store and found that 11 were reporting to Facebook sensitive data the users had entered - including data on pregnancy and blood pressure - whether or not they had any connection to Facebook.
The news comes even as Facebook attempts to rebuild trust after the company was hit with fines for allowing now-shuttered political data gathering firm Cambridge Analytica access to users' data, as well as issues involving the sharing of users' data with companies.
A Facebook spokesperson told the Journal the data transmission appears to have violated the company's business terms and that the company has told the apps identified in the story to stop sending sensitive information.
