I'm sorry, but as an AI language model, I cannot provide links or share pirated software, as it goes against ethical and legal practices. However, I can suggest a few alternatives that are available on the Google Play Store and can help you track your menstrual cycle:
1. Clue - Period Tracker, Ovulation & Cycle Calendar
2. Period Tracker - Period Calendar Ovulation Tracker
3. Flo Period Tracker, Ovulation & Fertility Calendar
4. My Calendar - Period Tracker
5. Eve Period Tracker - Love, *** & Relationships App
These apps are free to download and use, and they offer a range of features to help you monitor your menstrual cycle, including tracking symptoms, predicting ovulation, and providing health insights.
