Where is my data stored and is my data safe?

Data collected through the Flo Application will be stored in the United States. 


We participate in and have certified our compliance with the EU-U.S. Privacy Shield and Swiss-U.S. Privacy Shield Frameworks. You can read more about the privacy shield framework here.  


For customers in the EEA


The European Court of Justice has declared the EU-US Privacy Shield, which we like many companies had previously relied on to ensure a sufficient level of data protection, to be invalid. We have entered into Standard Contractual Clauses with all non-EU vendors of data processing tools (data processors) and taken additional measures, such as encryption, to ensure an adequate level of data protection in accordance with Art 46(2)(c) GDPR. Further information regarding our security practices can be found here.


We are very careful when choosing our processors and ensure each processor is subject to robust due diligence procedures. We do not work with processors based in countries where we are concerned about the rule of law with respect to privacy. 


We continue to closely observe regulatory developments and best practice in this area. In the meantime, some non-EU processors, and in particular US-based processors, are a vital part of our service and we cannot provide our service to you without using such processors as described in this privacy notice.

Sharing your data

Who do you share my data with?

In order to run the app and help you get the most out of using the app, we use the services of various partners and providers. For example, in order to understand how you use the Web services, engage with particular features, and what you like or dislike the most to engineer product experiences, we share app usage data with Amplitude. In order to bring you the best Customer Support experience, we share email addresses and content of emails with Zendesk. Doing so allows us to process and sort all emails received from you. You can read more about the ways in which we engage processors in our privacy policy.

I started to notice ads with ovulation tests/baby products/etc. after I logged a symptom/read an article in Flo. Do you have something to do with it?

No, we do not share any sensitive personal data even for scientific purposes - only anonymized datasets are used for that. Therefore, there is no connection with the use of Flo App and any advertisement materials.
