Terms and Conditions

Last updated: April 03, 2025

Please read these Terms and Conditions ("Terms") carefully before using the PPTX Compressor application ("the App") or its source code ("the Code"). By downloading, installing, or using the App, or by accessing, cloning, or contributing to the Code, you agree to be bound by these Terms. If you do not agree, do not use the App or the Code.

1. Definitions

  • "App" refers to the PPTX Compressor desktop application, including all associated files, installers, updates, and components downloaded during first launch.
  • "Code" refers to the source code, documentation, scripts, and configuration files in the PPTX Compressor repository.
  • "Author" refers to SnoopyCodeX, the creator and maintainer of the project.
  • "User" refers to any person or entity that uses the App or the Code.

2. Use of the Application

2.1 Permitted Use

The App is provided free of charge for personal, educational, and commercial use. You may:

  • Use the App to compress PowerPoint (.pptx) files for any lawful purpose.
  • Install the App on multiple devices that you own or control.
  • Share the official installer download link with others.

2.2 Restrictions

You may not:

  • Redistribute the App installer or its compiled binaries under a different name or branding without prior written permission from the Author.
  • Remove, alter, or obscure any copyright notices, credits, or attribution within the App.
  • Use the App for any unlawful purpose or in violation of any applicable laws.
  • Reverse-engineer, decompile, or disassemble the compiled application, except as permitted by the open-source license governing the Code.

2.3 First-Launch Download

On first launch, the App downloads required compression tools (pptx_compressor.dll) from the official GitHub Releases page. This requires an active internet connection. The App does not collect, transmit, or store any personal data during this process. The only network requests made are to the GitHub API and GitHub Release asset URLs.

2.4 Auto-Update

The App may check for updates on startup via the GitHub Releases API. This behavior can be disabled in the App's Settings page. No personal data is collected during update checks.

3. Use of the Source Code

3.1 License

The Code is released under the MIT License (see LICENSE). You are free to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Code, subject to the conditions of the MIT License.

3.2 Attribution

If you fork, redistribute, or create derivative works based on the Code, you must:

  • Retain the original copyright notice and license in all copies or substantial portions of the Code.
  • Clearly indicate any modifications you have made.

3.3 Contributions

By submitting a pull request or contributing code to the repository, you:

  • Grant the Author a perpetual, worldwide, non-exclusive, royalty-free license to use, modify, and distribute your contribution as part of the project.
  • Confirm that your contribution is your original work or that you have the right to submit it.
  • Agree that your contribution will be licensed under the same MIT License as the rest of the project.
