Flo, the world’s most popular period-tracking app, was released in 2015 as a platform for users to track their menstrual cycles, sexual activity, physiological condition, and other reproductive healthcare-related information.

Privacy Policy

The full text of Flo's privacy policy can be found on their website at: https://flo.health/privacy-policy.

Written in plain English, it is easy to read and accessible to all users.

Data Collection

Flo collects data provided directly by users, such as personal information, well-being information (such as weight, BMI, menstrual cycle dates, and more), and with your consent, the data stored on third-party services like wearables; as well as personal data collected automatically such as device and IP data, and meta-data about the use of Services.

Data Sharing

With your consent, Flo may share some of your non-health data with AppsFlyer, a mobile marketing platform, which integrates partners to promote the app.

If your data is shared with other platforms for this purpose, except as explained in the policy, the app will ask for your consent.

You can withdraw your consent or opt out from the sharing of your personal data with AppsFlyer by adjusting your device settings in iOS or Android. You cannot opt out of AppsFlyers' processing of your personal data for onboarding purposes.

Privacy Rights

Users have the right to correct, restrict the processing of, access, request in a portable form, eras, and object to the processing of personal data. You can exercise these rights by contacting support@flo.health or exercise your right to erase your account in the settings of your app.

Data Security

Flo encrypts all data, engages in independent privacy audits, and recently received ISO 27001 certification, making it the first period- and ovulation-tracking app to achieve this milestone.

Information is based on the the privacy policy last updated on May 31, 2024.

Flo in the News

In 2021, the Federal Trade Commission finalized a settlement requiring Flo to obtain affirmative consent of users before sharing their personal health information with others and to obtain independent review of their privacy practices. This followed an FTC complaint made earlier that year in which the Commission alleged that Flo shared sensitive health data of millions of users with marketing and analytics firms including Facebook and Google.

After Roe v. Wade was overturned, followed by a wave of concern calling for users to delete their period-tracking apps, Flo rolled out its anonymous mode feature, which gives users the option to access the app without their name, email, and other technical identifiers from being associated with the health data.
