The verdict found Meta had ‘intentionally eavesdropped’ on Flo users’ in-app communications.

The tech company has lost a massive privacy case involving the Flo app that has raised huge questions about how health apps are secretly being used.

Meta lost a major privacy trial on Friday, with a jury in San Francisco ruling that the Menlo Park giant had eavesdropped on the users of the popular period-tracking app Flo.
