Device data

General technical data, such as phone model, OS version, country and language, is transferred to WomanLog servers solely for statistical purposes.

Personal data

Your email address is required in order to create your WomanLog account. Although a WomanLog account is not required for using our apps, it is recommended for backup and restoring data. If you create a WomanLog account, your WomanLog app data will be encrypted and stored on WomanLog servers ( Access to your data will only be possible by using the 'Sign In' feature with your WomanLog account (email address and password).

To create a WomanLog account, you will need to provide an email address. Your WomanLog account will only be created after verifying your email address by pressing the link in the confirmation email. If you want to delete your WomanLog account and the stored data, you can do so at any time by following these steps: open the WomanLog app, sign in to your WomanLog account in Settings -> WomanLog Account, press the button "..." in the right upper corner, and press on 'Delete Account.'

Health data

The optional "Intelligent Assistant" feature provides fine-tuned personalised menstruation and fertility forecasts, as well as other useful forecasts, all tailored to your data. You can use this feature only if you agree to send health data (such as body measurements, dates of your past and current periods, symptoms – all data except notes) from WomanLog apps to WomanLog servers. This data is stored and processed anonymously – no personal data is connected to this data. WomanLog utilizes this data to offer you 'Intelligent Assistant' services and to generate WomanLog sample data ('training data') for predicting menstruation and fertility. WomanLog apps will not share any of your health or personal data with third parties.
