The data we collect

When you use Flo, you provide information to us which can identify you, such as your name, your email address, your mobile service provider, and your IP address. This is commonly referred to as personal data.


We process personal data only when it serves a specific, explicit and legitimate purpose. If it is required by the law, we will ask your consent beforehand. 

General Information

When using Flo, you may provide us with your personal data such as your name, email address, gender, date of birth, password or passcode, place of residence and associated location information. This data is used to give access to the app, provide support, fulfill our legal obligations, and enable us to get in touch with you.

Setting up your Flo account and using the app

Information like name, email and passcode allows us to create your individual and unique account.

Getting your opinions & keeping you informed

We may send you surveys, product updates, and offers in order to improve your experience with Flo.

Health and Well-Being Data

As you use the app, you may choose to log your weight, body temperature, menstrual cycle dates, various symptoms related to menstrual cycle and health, and additional data including sexual and other well-being activities.


This data is used to provide our services as well as personalise the app and its features to your specific needs and interests. It may also be used for scientific research.

Providing more accurate predictions

Based on the data you log, Flo makes predictions about your future periods and ovulations. The more data you log, the more accurate predictions you get.

Showing content relevant to your needs & interests

We may offer you tailored multimedia content based on your preferences, symptoms, and other data you log into the Flo app.

Giving more insights thanks to other health & fitness products

If you decide to enable import of your records from smartwatches or other health apps, Flo can further adjust its predictions and offer you more relevant content.

Supporting medical research with aggregated health data

To support women’s health research run by acclaimed research institutions we may use some de-identified, aggregated data, which cannot be associated with you.

Usage Data

While you use the app, you interact with its various features and functions. This generates data like interactions with app features, frequency of use and usage patterns.


Knowing more about the ways people use the app helps us to identify areas for improvement and eventually better serve your needs.

Constant feature improvements for a better app experience

Knowing how our users interact with Flo helps us identify features that could be improved, adjusted, added or removed.

New language support

Learning that Secret Chats was popular in Brazil made us aware that it would be useful to offer it in Portuguese.

Improved content recommendations

Knowing what courses or articles resonate with you (e.g. sleep, nutrition) enables us to show you even more relevant content.

Device Data

Device information includes data like hardware model, information about the operating system and its version, unique device identifiers (e.g. IDFA), and mobile network information.


We use this data to improve the app’s performance, provide support and to promote Flo to potential new users.

Optimizing app performance

Having device and network information helps us optimise Flo, so that it can work on older devices and in areas with bad network coverage.

Providing quick & efficient support

Having access to information about your device’s operating system can help our support agents resolve issues quickly.

Helping more people discover Flo

To promote Flo, we may share a limited amount of data with marketing platforms (i.e. your age group, tech identifiers, general location and subscription status).

Location Data

Location information includes data like IP address, time zone and information about your mobile service provider.

This data helps us to be compliant with national regulations as well as provide our services and maintain the app.

Respecting the law

We always respect local laws. For example, by EU law, we can’t provide services to anyone below 16. So, knowing your location helps Flo to follow local rules & regulations.

Improving quality of translation

To improve the quality of translations, we may contact people in certain locations and ask their honest opinion about how our text reads in their local language.
