We, MISS GmbH, Breite 2, 82418 Murnau, Germany, are the EU distribution partner of Valley Electronics AG. Valley Electronics AG is the manufacturer of the fertility tracker Daysy and the provider of the smartphone app DaysyDay. As a Swiss company, we take data protection seriously and comply with the data protection regulations of the European Union. In the Netherlands you have direct contact with Patricia Dijkema from Daysy Netherlands, partner of Valley Electronics AG.

How do we protect your data?

Our guiding principles are:

Data protection and full transparency for our users.

Data encryption and pseudonymization on our servers.

We do not sell, share or profit from your information.

We would like to summarize the most important points of our privacy policy to show you what data we store and for what purpose.

The basic principle is that no personal customer data is stored without explicit permission. All data that we store about you is the result of your direct action.


As part of the ordering process, only the data needed to process your order on our website (such as address and payment details) are used, and only for this purpose. For tax reasons, the data will be archived and destroyed after the statutory retention period.

Privacy Policy


Your data, such as basal body temperature, menstruation and ovulation, are stored in Daysy and only used there to calculate your fertility. This personal space is only for you. Automatic data comparison with our server is not necessary for this calculation and therefore does not take place.



You can actively transfer data from Daysy to the DaysyDay smartphone app. This data is only processed to display your cycles and statistics.


To transfer this data, it is necessary for you to use our servers. Because we know how sensitive this data is, it is transferred encrypted and pseudonymised to our servers within the European Union and stored there.


This means that even if unauthorised third parties were to access the servers, your data (basal body temperature, menstruation, ovulation, fertility status) cannot be assigned to a specific person thanks to encryption and pseudonymisation. This special protection is very important to us. 

Customer service

If you contact us with a query and actively send us your data to process a request - for example, when you request a cycle analysis by our experts - you can rest assured that your data will only be used in the context of this specific request.  


As you can see, we have no interest in using your data for advertising purposes or collecting your data in a way that is not relevant to our product. Of course, we do not want to process data for resale either.
