Effective Date: November 20, 2025
This Privacy Policy explains how the Cycle Tracker App (the "App") manages user data. We are deeply committed to protecting your privacy, especially regarding sensitive health information.
The App collects the following personal health information:
Period Log Dates: The start dates of your menstrual cycles.
Cycle Settings: Your manually entered average flow duration and default cycle length.
All data collected by this App is stored locally on your device.
The App does not transmit, upload, or share your period log dates, cycle settings, or any other data with any external servers, third-party services, or cloud providers.
Your data remains solely within the runtime memory or local storage of the device on which the App is installed.
The App does not collect any personally identifiable information.
The sole purpose for collecting your period log dates and cycle settings is to provide the core functionality of the App:
Prediction: To calculate and display estimates for your next menstrual flow start, fertile window, and ovulation day.
Analysis: To determine your average cycle length and flow duration based on your logged history.
Since your data is stored locally, it is protected by the security features of your device (e.g., password, PIN, or biometric lock). We use standard internal security practices within the application to prevent unauthorized internal access to the data while the App is running.
You are in full control of your data.
Removing Data: You can delete individual period logs directly within the App's interface.
Full Deletion: If you uninstall the App from your device, all locally stored data associated with the App will be permanently deleted from your device.
The Cycle Tracker App does not integrate with or share data with any third-party analytics services, advertising networks, or data brokers.
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy within the App. You are advised to review this Privacy Policy periodically for any changes.
If you have any questions or concerns about this Privacy Policy, please contact the app developer through the contact method provided where you downloaded the App.
