By downloading or using Posy, you agree to these Terms of Use. Please read them carefully.
These Terms of Use govern your use of the Posy Period Tracker app ("Posy", "the App"). By using the App you agree to be bound by these terms.
Posy offers an optional auto-renewable subscription called Posy Premium, which unlocks additional features including extended cycle predictions, full cycle history, and PDF health report export.
Core period tracking features — including period logging, symptom and mood tracking, cycle predictions, and reminders — are free and will remain free forever.
Posy is intended for personal, non-commercial use. You agree not to misuse the App, attempt to reverse-engineer it, or use it for any unlawful purpose.
Posy is a personal health tracking tool and is not a medical device. The information provided by the App — including cycle predictions and fertile window estimates — is for informational purposes only and should not be used as a substitute for professional medical advice, diagnosis, or treatment.
All your health data is stored locally on your device. We do not collect, store, or transmit your personal data. For full details, see our Privacy Policy.
All content, design, and code in Posy are the property of the developer. You may not copy, modify, or distribute any part of the App without prior written permission.
We may update these Terms of Use from time to time. We will notify you of any significant changes by updating the "Last updated" date above. Continued use of the App after changes constitutes acceptance of the new terms.
