New guide: What your period tracker could know about you

For millions of people, period tracking apps have become part of everyday life. 

They help people understand their menstrual cycles, manage symptoms, plan pregnancies and gain valuable insights into their reproductive health. But to provide those features, period tracker apps often collect some of the most personal information anyone will ever enter into a smartphone. 

Many people never stop to think about what happens to that information once they’ve entered it. 

But recent legal action involving the Flo period tracking app has prompted many users to ask important questions about how their health data is collected, used and shared. 

The Flo data privacy case

In the US, Flo Health, Google and Flurry have agreed to a proposed $59.5 million settlement to resolve claims alleging that deeply personal health information was shared with third parties without users’ knowledge or informed consent.

The companies deny the allegations and have not admitted liability. 

As lawyers explore a potential UK claim, many people are also asking important questions about how period tracking apps collect, use and protect sensitive health information. 

Whether or not you ever used Flo, the case has prompted an important conversation about digital privacy. 

Why this matters

Unlike your shopping history or streaming habits, period tracking apps can reveal some of the most significant moments in your life.

For some people, that’s a positive pregnancy test or the excitement of trying for a baby.

For others, it may be fertility treatment, pregnancy loss, perimenopause or ongoing health concerns. 

Many people would only ever share that information with those closest to them or a healthcare professional.

That’s why questions about how this data is collected, stored and shared matter.
