Overview
Flo is one of the world’s most popular period and fertility tracking apps, trusted by more than 100 million people to track their cycles, pregnancies and reproductive health.
A recent $59.5 million US settlement has raised serious questions about how some of that deeply personal information was handled.
The US lawsuit alleged that, between 30 June 2016 and 23 February 2019, Flo shared users’ intimate health data — including information about menstruation, pregnancy and sexual activity — with third-party companies such as Google, Meta and Flurry without users’ full knowledge or consent.
Flo Health, Google and Flurry have agreed to settle the claim for $59.5 million, but all continue to deny any wrongdoing. The settlement was reached to avoid the cost and uncertainty of ongoing litigation.
If you used the Flo app in the UK during this period, you may be wondering whether your information was affected too. While the US settlement only applies to eligible American users, UK law firms may investigate whether similar legal action could be brought here.
We’re monitoring developments closely. If one of our trusted UK partner law firms takes this claim forward, we’ll help you understand what it means, who could be affected and how to find out whether you’re eligible.
At a glance – Flo privacy claim
What do we know about the Flo data breach?
Lawsuits have been brought in the US and Canada alleging that Flo shared users’ intimate health data with third parties, including Google, Meta and Flurry, without users’ full knowledge or consent.
In July 2026, Flo Health, Google and Flurry agreed to pay $59.5 million to settle the US claims. The companies deny any wrongdoing, and the settlement was reached to avoid the cost and uncertainty of continuing the litigation.
The allegations relate to data entered into the Flo app between 30 June 2016 and 23 February 2019, including information about menstruation, pregnancy and reproductive health.
UK law gives health data special protection, and if personal information was shared without a lawful basis or your consent, you could also have a claim.
Did Flo betray your trust?
If you used the Flo app between 30 June 2016 and 23 February 2019, your intimate health information may have been shared with third parties without your knowledge or consent.
If you trusted Flo with some of life’s most personal moments, and that trust was violated, you deserve the opportunity to seek justice.
