GANSU2 Terms and Conditions
===========================

Copyright (c) 2025-2026 Hiroshima University and Fujitsu Limited. All rights reserved.

GANSU2 is distributed in binary form under the terms below (the same terms
published at https://gansu2.github.io/en/TERMS/). It is NOT distributed under the BSD-3-Clause
license of the upstream GANSU project; see NOTICE for the upstream notice and
the third-party components.

By using GANSU2, you agree to the following terms.

Disclaimer of Warranty
----------------------

GANSU2 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, and non-infringement. In no event shall the authors or copyright holders be liable for any claim, damages, or other liability arising from the use of the software.

License and Permitted Use
-------------------------

A license key obtained through the User Portal (https://gansu2.github.io/portal/) permits any use of GANSU2, including commercial use, subject to the period and Max Size limit shown on your portal dashboard.

Without a license key, GANSU2 still runs, but the workload size is limited (Max Size). When the limit is reached the run stops with a message explaining how to obtain a key; nothing is silently reduced — GANSU2 never lowers the basis set, method, or accuracy to fit a limit.

Account- and license-specific terms are set out in the User Portal Account Terms of Service (https://gansu2.github.io/en/PORTAL_TOS.html).

Prohibited Actions
------------------

The following actions are prohibited without prior written permission from the copyright holder:

- Reverse engineering, disassembly, or decompilation of the software or its libraries.
- Redistribution of the software, in whole or in part, to third parties.
- Sublicensing or granting any rights in the software to third parties.
- Circumventing the license activation, machine-binding, verification, or rate-limit mechanisms.
