Mensinator is an open source privacy respecting period tracking app for Android
Mensinator provides a clean and intuitive interface for tracking your menstrual cycle, monitoring your periods, and viewing essential statistics—all without the need for sign-ups or sharing personal data. All information is stored securely on your device, ensuring your privacy is always protected.
It's not the only such app on F-Droid, but coming from F-Droid means it is proper compiled open source code, and says what it does. There is no Big Tech company requiring registration to install it, or having privacy intrusive adverts inserted (which usually track and report locations).
There are a few countries in the world today where such information needs to be kept private to protect their citizens' privacy. Open source respects the individual's right to decide how they want to use their software.
