7.1 No Medical Advice

The App provides general health, menstrual, and reproductive wellness information for educational purposes only. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease or condition. Information in the App, including articles, insights, and predictions, is not a substitute for professional medical advice, diagnosis, or treatment.

7.3 Cycle, Period & Fertility Predictions

Period, ovulation, and fertile-window predictions shown in the App are statistical estimates based on the cycle history you log.
