SARGENT END USER LICENSE AGREEMENT

Copyright (c) 2026 Damdae Park. All rights reserved.

This End User License Agreement ("Agreement") governs the use of Sargent, the process simulation software
distributed as compiled packages (wheels) with its data, documentation and example models (the "Software").
By installing or using the Software you agree to this Agreement. If you do not agree, do not install or use it.

1. Ownership
   The Software is licensed, not sold. Damdae Park (the "Licensor") retains all right, title and interest in the
   Software, including all intellectual property rights. No rights are granted except those expressly stated here.

2. License for academic and non-commercial use
   Subject to this Agreement, the Licensor grants you a free, non-exclusive, non-transferable, revocable license to
   install and use the Software for:
   (a) academic research and teaching at universities, research institutes and other non-profit organizations; and
   (b) personal, non-commercial evaluation and learning.
   Results obtained with the Software may be published (see section 5).

3. Commercial use
   Any use of the Software by or for a for-profit entity, for consulting or other paid services, for the design or
   operation of commercial plants, or as part of a commercial product or service requires a separate written
   commercial license from the Licensor. Contact the Licensor (section 10) before such use.

4. Restrictions
   You may not, and may not allow others to:
   (a) copy, distribute, publish, sell, rent, lease, sublicense or otherwise make the Software available to any
       third party, except copies of the unmodified packages within your own organization for uses allowed by
       section 2;
   (b) reverse engineer, decompile, disassemble or otherwise attempt to derive the source code, algorithms or
       internal structure of the Software, except to the extent that applicable law expressly permits it despite
       this restriction;
   (c) modify, adapt, translate or create derivative works of the compiled parts of the Software;
   (d) remove, alter or obscure any copyright, license or attribution notice of the Software;
   (e) use the Software to build a competing simulator or to provide it as a hosted service to third parties.

5. Citation
   If you publish work (articles, theses, reports, presentations) that uses results obtained with the Software,
   please cite the Software as:
     Damdae Park, Sargent: an integrated process systems engineering platform,
     https://github.com/damdaepark/sargent
   or the reference publication indicated at that address once it is available.

6. Third-party components and services
   The Software uses third-party open-source libraries (installed as dependencies under their own licenses) and can
   connect to third-party software and services that you license and run yourself (for example Aspen Plus, DWSIM,
   AI model providers and life cycle inventory databases). This Agreement does not grant any right to those
   products; their use is governed by their own terms.

7. No contributions
   The Licensor does not accept external code contributions to the Software. Feedback you choose to give may be
   used by the Licensor without obligation.

8. Disclaimer of warranty
   THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO
   THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY AND NON-INFRINGEMENT. Simulation,
   economic and environmental results are estimates; you are solely responsible for checking them before relying on
   them for any design, investment, safety or regulatory decision.

9. Limitation of liability
   TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL THE LICENSOR BE LIABLE FOR ANY DIRECT,
   INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES (INCLUDING LOSS OF DATA, PROFITS OR BUSINESS,
   OR DAMAGE TO PROPERTY OR EQUIPMENT) ARISING OUT OF OR IN CONNECTION WITH THE SOFTWARE OR ITS USE, EVEN IF
   ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

10. Termination and contact
   This license terminates automatically if you breach this Agreement; you must then stop using and delete all
   copies of the Software. The Licensor may change the terms for future versions of the Software.
