Privacy Policy

This Privacy Policy explains how this application (“the App”) handles your information. The App is designed to be simple, private, and secure. We do not collect, store, or transmit any personal data to external servers.

1. No Data Collection

The App does not collect, store, or process any personally identifiable information. All calculations and features operate entirely on your device. No information is transmitted to the developer or any third party.

2. Local Storage Only

The App may save certain preferences (such as your last selected period date or language choice) using your browser’s local storage. This data remains on your device only and is never uploaded or shared. You may clear this data at any time by deleting your browser storage or using the App’s “Clear saved date” option.

3. No Cookies or Tracking

The App does not use cookies, analytics tools, tracking scripts, or any form of behavioral monitoring. Your activity is not tracked or analyzed.

4. No Third‑Party Services

The App does not integrate advertising networks, analytics platforms, or any third‑party data processors. Because no data is collected, no information is shared with external services.

5. Children’s Privacy

The App does not knowingly collect information from children under the age of 13. Because no data is collected or transmitted, the App is inherently compliant with COPPA and similar child‑privacy regulations.

6. Security

Since all data remains on your device, you are responsible for the security of your own device and browser. The developer does not have access to your information and cannot recover or view any stored data.

7. Future Changes

This Privacy Policy may be updated if new features are added in the future, such as analytics or advertising. Any updates will reflect the App’s current data practices. Continued use of the App after changes are published constitutes acceptance of the updated policy.

8. Contact

If you have questions about this Privacy Policy, please contact the developer of the App.
