When you get started with Natural Cycles, you will be asked a series of questions that will help the algorithm get to know your unique cycle so that you can have the most tailored experience possible.
If you made a mistake or need to re-answer these questions for any reason, you can go to the menu in the top left corner of the app > Settings > Answer setup questions again.
Please note that the setup questions are only available for 60 days after activating your account. After 60 days, you will no longer have the option to modify the answers since the algorithm should have gathered enough information about your cycle from the data you have logged, so it won’t rely on your answers to the setup questions as much as it did initially.
The algorithm always puts more weight on your most recent data when predicting your cycle, which is why your answers to the setup questions will have less and less impact on your app experience as time goes on.
If you can’t answer your set-up questions anymore, the best thing to do is continue to log data regularly, and the algorithm will quickly adapt.
