About the study

Why we’re doing this

Why we’re doing this

We want to understand Flo’s role in helping women and people who menstruate to learn more about their reproductive health, and how using the app improves their health and well-being.
How it works

How it works

Recruits will be split into two groups at random – the interventional group will use Flo for 3 months to track and monitor their health, the control group won’t.

All recruits will complete a health and well-being survey at the start of the study, then follow-up surveys after 6 weeks and 3 months.

We firmly believe women’s health data should be held with the utmost privacy and care. We care deeply about our users’ privacy, which is why Flo does not share health data with any company but Flo. We’ll never disclose your replies to any third party. We never have and never will sell your personal health data to any company.

  • If you participate, we will collect sensitive personal data. However, all analysis data will be aggregated and de-identified, which means you cannot be personally identified from your responses. The data we’ll collect may include your ethnicity, level of education and income, health data (including your current reproductive health goals, medical history of health conditions, and use of healthcare resources), information about your relationship with a partner, and overall quality and satisfaction with your life and well-being. 
  • We’ll also collect your email address to link your survey data to the Flo app data. We do this in order to find out whether your app engagement influences health benefits gained. Providing this information is voluntary, but if it isn’t provided, you may not be able to participate in the study. 
  • We’ll also analyze your app engagement information. For example, we may analyze the content you accessed, features you used, your time spent in the app, and how often you use it. You are welcome to read our Privacy Policy, which will give you information about how your personal information is processed when you use the Flo app. 
  • When you share your data with Flo, you have the opportunity to move women’s health research forward. We may use the aggregated and anonymised data for research purposes and to create any marketing materials sharing study results. You can read more about the types of research we do here
  • You can freely talk to us. We believe in transparent and open dialogue, so we strongly encourage you to contact our Support Team at support@flo.health, our Data Protection Officer at dpo@flo.health if you want to exercise your privacy rights, have questions about how we collect or process your Personal Data, or anything else related to our privacy practices.
