This Privacy Policy has been effective from July 09, 2025.
Please read the Privacy Policy before using the application.
Luna is designed with your privacy in mind. All of your personal data and cycle information is stored locally on your device. We do not collect, store, or transmit any of your personal information to our servers or third parties.
When you use the application, it may automatically collect limited technical data. This data may include:
This data is only used to support app functionality (e.g., localizing language) and is not stored or shared by us.
Since your data never leaves your device, we don't use it for any purpose beyond providing period tracking functionality, predictions, and insights about your cycle. Language settings are used to automatically display the app in your preferred language.
We do not share your data with any third parties. If you choose to use the export feature, you control where your data goes and who has access to it. The multi-user feature only shares data between profiles on the same device.
Your data is stored securely on your device using Android's built-in data protection mechanisms. We recommend using your device's screen lock feature for additional security.
You have complete control over your data. You can export, delete, or modify your data at any time through the app's interface. If you uninstall the app, all data will be removed unless you have created an external backup.
