In January 2021, Flo Health and the U.S. Federal Trade Commission reached a settlement over the company’s sharing of sensitive reproductive data collected through its period-tracking app with data analytics companies.

In October 2021, several lawsuits against Flo Health, major tech companies Meta and Google, and other smaller data analytics firms over these practices were consolidated in a single class-action lawsuit, Frasco v. Flo Health, before a federal court in California.

Google, as well as other defendants, settled the lawsuit before the trial began. Flo Health settled it before the proceedings concluded, leaving Meta as the only remaining defendant.

In August 2025, a jury found that Meta had breached the app users’ privacy in intercepting their reproductive health data, a finding the company disputes.

In September 2025, a judge rejected Meta’s request to overturn the verdict.
