Overview
Flo is one of the most popular period and fertility tracking apps in the world — used by over 100 million people to monitor their cycles, pregnancies, and intimate health. But recent legal action suggests that trust may have been broken.
Multiple class action lawsuits have been launched against Flo Health Inc., alleging the app collected and shared users’ most private health data — including menstrual cycles, pregnancy status, and sexual activity — with companies like Facebook (Meta), Google, and others, all without users’ full consent.
And if you used the Flo app, your data may have been part of it.
At Join the Claim, we’re keeping a close eye on the legal developments. If a UK claim is launched, we’ll help you check if you’re eligible and connect you with a trusted law firm.
