Terms of Use

These Terms of Use govern your use of an offline app for exploring information and visualizations about celestial objects. By downloading or using the app, you agree to these terms.

Effective September 4, 2026

This policy reflects an offline app with no analytics, advertising, accounts, or cloud sync.

1. Acceptance of terms

By downloading, installing, or using the app, you agree to these Terms of Use. If you do not agree, do not use the app. If you are under the age of legal majority where you live, a parent or guardian must review these terms with you.

2. Purpose of the app

The app provides offline educational and recreational information, illustrations, and visualizations relating to stars, planets, moons, constellations, and other celestial objects.

The app is not a professional observatory tool, navigation system, emergency service, or source of scientific, medical, legal, or safety advice. Celestial positions, scales, colors, distances, and other representations may be simplified or approximate.

3. Acceptable use

You may not:

  • copy, redistribute, rent, sell, sublicense, or commercially exploit the app except where permitted by law;
  • reverse engineer, decompile, or attempt to extract source code except where applicable law expressly permits it;
  • remove copyright, trademark, attribution, or other proprietary notices;
  • use the app in a way that violates applicable law or the rights of others; or
  • misrepresent the app’s educational visualizations as verified real-time observations or professional guidance.

4. Intellectual property

The app, its design, software, original text, graphics, and organization are owned by or licensed to the developer and are protected by applicable intellectual-property laws. Names and factual data relating to celestial objects may come from public scientific sources and remain subject to any applicable source terms and attribution requirements.

5. Disclaimer of warranties

To the maximum extent permitted by law, the app is provided “as is” and “as available.” We do not guarantee that it will be uninterrupted, error-free, completely accurate, or suitable for a particular purpose. Nothing in these terms excludes warranties or consumer rights that cannot legally be excluded.

6. Limitation of liability

To the maximum extent permitted by law, the developer will not be liable for indirect, incidental, special, consequential, or exemplary losses arising from use of, or inability to use, the app. This limitation does not apply where liability cannot be limited under applicable law.

7. Termination

These terms remain effective while you use the app. Your right to use the app ends if you materially violate these terms. You may stop using the app at any time by deleting it from your device.

8. Applicable law

These terms are governed by applicable law, including any mandatory consumer-protection rules in your place of residence. Any dispute should first be raised by emailing so the parties can attempt an informal resolution.

9. Changes and contact

We may revise these terms when the app or applicable requirements change. Updated terms will be posted on this page with a new effective date. For questions, contact the developer at .
