MEBA Stacker — End User License Agreement (EULA)

Last updated: August 24, 2026 · Version 1.0-draft

This End User License Agreement ("Agreement") is between you and [LLC NAME, e.g. "MEBA Software LLC"] ("we", "us") and governs your use of the MEBA Stacker software ("Software"). By installing or using the Software you agree to this Agreement. If you do not agree, do not install or use the Software.

1. License grant

Paid license. On purchase, we grant you a personal, non-exclusive, non-transferable, perpetual license to install and use the Software on up to three (3) devices that you own or control, for personal or commercial use. All updates within the same major version (1.x) are included at no additional charge.

Trial license. Before purchase, we grant you a 45-day evaluation license with full functionality. After the trial ends, the Software will stop processing new images until a license key is entered; your existing image library and previously produced results remain accessible and exportable at all times.

Beta builds. Pre-release ("beta") builds are provided free of charge for evaluation, may contain defects, and expire on a date embedded in the build, after which an update is required to continue processing. Beta builds are provided strictly as-is.

2. What you may not do

You may not: (a) redistribute, sell, rent, sublicense, or host the Software for third parties; (b) share license keys beyond your own devices; (c) reverse engineer the Software except where such a restriction is prohibited by law; (d) remove or alter copyright, attribution, or license notices; (e) use the Software to violate any applicable law.

3. Your content

Your images, raw frames, masters, and processing results are yours. We claim no rights over any content you create with the Software. The Software reads your image files; it does not modify or delete your original capture files.

4. Telemetry and reports (opt-in)

The Software can send anonymous processing reports to help improve results (see the Privacy Policy). This is opt-in, contains no personal information, no file paths, and no full-resolution images, and can be declined. Beta builds may require reporting as a condition of participating in the beta program.

5. Third-party components

The Software includes or downloads third-party components under their own licenses, including: nox (MIT, © charvey2718; portions © Nikita Misiura); Cosmic Clarity (MIT, © Franklin Marek); ASTAP command-line solver (MPL-2.0, © Han Kleijn — invoked as an unmodified separate program); NVIDIA CUDA/cuDNN runtime redistributables (NVIDIA license terms, optional GPU pack); TensorFlow (Apache-2.0); and other open-source libraries listed in the in-app attribution file. Star catalogs and astrometric databases are subject to their respective providers' terms.

6. Updates and availability

We may provide updates that add, change, or remove features. Online features (update checks, license validation, optional report uploads) require an internet connection; core image processing runs locally and offline. License validation includes an offline grace period of at least 14 days.

7. Refunds

See the Refund Policy ([LINK]), which is incorporated into this Agreement. Where a refund is granted, the associated license key is deactivated.

8. Disclaimer of warranty

THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SOFTWARE WILL BE ERROR-FREE OR UNINTERRUPTED, OR THAT ANY PARTICULAR PROCESSING RESULT WILL BE ACHIEVED.

9. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY ARISING OUT OF OR RELATED TO THIS AGREEMENT SHALL NOT EXCEED THE AMOUNT YOU PAID FOR THE SOFTWARE IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, AND WE SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES, INCLUDING LOSS OF DATA OR PROFITS. Some jurisdictions do not allow certain limitations; in those jurisdictions our liability is limited to the maximum extent permitted.

Nothing in this Agreement limits liability that cannot be limited by law, and nothing affects the statutory rights of consumers in jurisdictions (including the EU and UK) where such rights cannot be waived.

10. Sales through Paddle

Purchases may be processed by Paddle.com, acting as merchant of record. Paddle's checkout terms apply to the payment transaction; this Agreement governs your use of the Software.

11. Termination

This Agreement terminates automatically if you materially breach it. On termination, your license ends and you must stop using the Software. Your own content is unaffected.

12. General

This Agreement is governed by the laws of Texas, USA, excluding conflict of law rules. If any provision is held unenforceable, the remainder stays in effect. This Agreement is the entire agreement regarding the Software and supersedes prior communications on the subject.
