Flo Period Tracker Under Fire for Sharing User Data with Meta

A privacy controversy has erupted around the popular period tracking app Flo, which has been caught selling sensitive user health data to Meta. The revelation, which surfaced on Hacker News, has sparked outrage among privacy advocates who warn that the most intimate health information is being treated as a commodity. The app, widely used by women to monitor menstrual cycles and fertility, reportedly shared users' data including cycle dates, symptoms, and other reproductive health details with Facebook's parent company. This practice raises serious concerns about data privacy, especially given the highly personal nature of the information collected. Flo has not yet issued a public statement addressing these allegations.
