Terms & Policy

Last Updated: 12/12/2025

Introduction

Welcome to SPACEAPP – a hybrid satellite tracking application.

These terms outline the fair use and expectations while using the SPACEAPP software. Created and maintained by the SPACEAPP Team (primarily by Vo Tan Binh, a.k.a. Henry Vo), this application is provided for personal use under defined conditions.

By downloading, running, or modifying the app, you agree to follow the principles of responsible, respectful, and non-commercial use as described below.

Use of Service

This software is distributed as a free tool for educational, personal, or experimental purposes. Commercial redistribution or repackaging is not permitted unless explicitly approved by the original authors.

What You Agree To:

  • Use this software responsibly and only for lawful, constructive purposes.
  • This software is provided ‘as is’, without warranty of any kind. The authors disclaim all liability for damages resulting from use or inability to use the software.
  • Do not remove credits, modify authorship, or claim original ownership of the app.
  • Respect third-party services such as the N2YO API and adhere to their external usage terms.
  • Open-source modules are provided for educational use and permitted modification, but commercial use, redistribution, or rebranding is not allowed.

Usage Terms:

This application remains free for personal use. Some modules are offered as open-source, but any redistribution, modification, or reuse of the app or its open-source components must always retain full credit to Vo Tan Binh (Henry Vo) and must not be used for commercial or illegal purposes.

Privacy and Data

SPACEAPP is designed as a plug-and-play local application. User data is stored only on the local device, and the author is not responsible for any loss or leak of such data.

Transparency Commitment:

  • The website uses temporary cookies solely to maintain login/logout status during sessions. These cookies do not track personal information or web activity.
  • The application runs locally on your machine. No personal data is ever sent or stored externally.
  • Purchasing source code does not require any sensitive information; all transactions are handled by the payment provider.
  • Your N2YO API key is stored only on your device. Users are responsible for keeping their keys private.
  • The application does not include telemetry, trackers, analytics, or hidden data collection.
  • Open-source repositories may display public GitHub contribution metadata, but the app itself does not collect personal data.

Respecting External Services:

SPACEAPP interacts with public APIs (e.g., N2YO) which may have their own terms. Users are responsible for understanding those external policies before use.

Modifications and Contributions

SPACEAPP is a hybrid project: the main application remains closed-source, while selected modules and tools are released as open-source resources. Developers may explore, learn from, or extend these open-source components, but the core application is not open for public forks or republishing.

What You Should Know:

  • The core SPACEAPP application may not be forked, republished, or redistributed in any form.
  • Open-source modules provided by the author must retain full credit to Vo Tan Binh (Henry Vo) in all reused or modified versions.
  • Open-source components may not be used for illegal, harmful, or commercial purposes unless explicit permission is granted.
  • The project may evolve over time; we may update or discontinue features, modules, or licensing terms based on technical constraints or misuse.
  • Continued use of SPACEAPP resources indicates acceptance of the most recent version of these terms.

Licensing Notice:

SPACEAPP uses a custom licensing model. The main application is fully closed-source, while selected modules are released under a limited open-source license requiring attribution and non-commercial use. These terms are unique to SPACEAPP and are not equivalent to MIT, GPL, or any public open-source license. All rights remain with the original developers.
