Jury Finds Meta Violated Flo Period Tracker Users' Privacy in Lawsuit Verdict — What Happens Now?

The Flo period tracking app's involvement in a lengthy legal battle has come to an end. The company — which allowed people to enter information about their menstrual cycle in order to track their period, identify patterns, and even predict fertility windows — was accused of sharing private user data with several tech companies.

Flo, Google, Meta, and Flurry were all named in a 2021 lawsuit filed by users, who say that their data had been used for targeted advertising without their consent.

This was in direct conflict with Flo's user agreement, which said it would keep the sensitive data about people's reproductive health private.

While Flo, Google, and Flurry reached a settlement outside of the trial, Meta remained in the legal hot seat and was subject to a trial by jury. On Aug. 11, 2025, the jury reached a verdict in the Flo period tracker lawsuit.

Here's everything we know about what they decided.

According to The Verge, Flo users say that their data was shared by the period tracker from November 2016 to February 2019. During that time, the lawsuit alleged that Flo users' data was shared with the tech companies for the purpose of targeted advertising. This prompted the users to come together to file a class action lawsuit against the company in 2021.

The jury finally reached a verdict in August 2025, agreeing with the claims from the Flo users.

They found a "preponderance" of evidence, according to The Verge, and said it was clear that Meta had "intentionally eavesdropped on and/or recorded conversations using an electronic device,” without the consent or knowledge of the app's users.

This is a violation of California's Invasion of Privacy Act and the state's wiretap law.

It took the jury a very long time to reach their verdict, so it stands to reason that it may take them a little bit to figure out the financial compensation portion of their decision as well. While no number was given alongside of the August finding, The Verge estimates that Flo's financial obligation could turn into a significant one.

That's because the state of California says that each violation of the Invasion of Privacy Act could result in a $5,000 penalty.

The Flo users in the lawsuit number in the millions, meaning the company could be looking at an eyewatering amount.

But that doesn't mean everyone should expect a huge payday as a result of the lawsuit. The Verge reports that Meta objected to the verdict after it was handed down, which means there is a significant chance that the company will appeal the decision.

Meta even released a statement about the findings, hinting at how the company feels about the ruling.

“We vigorously disagree with this outcome and are exploring all legal options,” TechCrunch reported. “The plaintiffs’ claims against Meta are simply false. User privacy is important to Meta, which is why we do not want health or other sensitive information, and why our terms prohibit developers from sending any.”

Only time will tell how this plays out for Flo users.
