Data Security

We take reasonable measures to protect user information and improve app security. However, no method of electronic storage or transmission over the internet is completely secure.

Disclaimer

The app calculations are based on astronomical formulas and estimations. While we strive to provide accurate information, timings and calculations may occasionally be inaccurate due to factors such as device settings, location accuracy, atmospheric conditions, or calculation limitations.

This includes Sunrise/Sunset, Golden Hour, Blue Hour, Twilight, Moon Phase, Moonrise/Moonset timings, and results from the photography calculator tools — including the Pro Settings Calculator (Beta), which may be subject to further changes and refinements during its beta period.

Users should verify important timing information independently when accuracy is critical.

Like other calculators in the app, Moon Phase, Moonrise/Moonset data, and the Pro Settings Calculator (Beta) rely on the same location and astronomical-calculation inputs described above, and do not involve any additional data collection.

Children’s Privacy

The app is not intended for children under the age of 13. We do not knowingly collect personal information from children.

Changes to This Privacy Policy

This Privacy Policy may be updated from time to time. Any updates will be reflected within the app or on the app listing page.
