Copyright © 2026 Lingyuan Kong and Zhengran Wu. All rights reserved, except for the limited permissions expressly granted below.
Gewu Insight is source-available research software. It is not offered under an open-source license. Public availability of source code does not grant commercial rights. This is a custom license, not MIT, Apache, GPL or another standard license.
1. Scope and ownership
"Software" means the original Gewu Insight source code, binaries, documentation and other original project materials made available under this License, only to the extent the copyright holders have the right to license them. Third-party components and materials are excluded and remain subject to Section 6. "You" means the individual or organization exercising the permissions below. The copyright holders retain ownership of the Software and reserve every right not expressly granted, including the right to offer separate commercial licenses.
2. Permitted research use
Subject to this License, the copyright holders grant You a worldwide, non-exclusive, royalty-free, non-sublicensable permission to download, copy, install, build, run, study and modify the Software solely for academic or other non-commercial research, education related to that research, evaluation and reproduction of scientific results ("Permitted Research Use").
Permitted Research Use must not be directed toward commercial advantage, commercial product or service development, or paid services for another party. Academic affiliation or nonprofit status alone does not make an activity non-commercial. Research salaries, ordinary academic grants, tuition, and publication in journals that charge fees do not alone make otherwise permitted academic research commercial. Research performed for a commercial sponsor's product development, exclusive commercial exploitation or business operations requires separate written authorization. Contact the copyright holders before using the Software if the proposed purpose is unclear.
3. Non-commercial research sharing
You may share copies of the Software, including modified versions, derivative works and patches, in source or binary form, without charge, solely to support Permitted Research Use, provided that:
(a) You include this complete License, preserve copyright and attribution notices, and retain applicable third-party licenses and notices;
(b) You identify the original version, clearly mark modifications and their dates, and do not imply that a modified version is an official release or that the authors endorse Your research, distribution or organization;
(c) You distribute the Software under these same permissions and restrictions, without granting broader rights; and
(d) the distribution is not part of a commercial product, paid service, commercial offering or promotion for commercial advantage.
These permissions include public research forks and pull requests within the conditions above; no separate written authorization or contributor agreement is needed merely to make or share them. Each recipient receives permission for the copyright holders' Software directly under this License. License Your original modifications under these same research-use and sharing terms when distributing them with the Software, to the extent You have authority to do so. This does not permit commercial redistribution or broader sublicensing or relicensing.
You retain any copyright in Your own original changes. Sharing a modification or submitting a pull request does not transfer its ownership or grant the project authors additional commercial licensing rights. Acceptance into the official project is a separate decision; maintainers must obtain any additional contributor authorization needed for commercial licensing before merging. See CONTRIBUTING.md. This License is not a contributor license agreement.
4. Commercial and other reserved uses
Without separate prior written authorization from the copyright holders, You may not use the Software for commercial purposes, commercially redistribute it, sell or license access to it, sublicense or relicense it, or incorporate any covered portion into a commercial product or service. This includes commercial internal use and R&D, consulting or contract services, paid hosted services, SaaS, and commercial distribution of modified versions, whether or not the Software is separately priced.
You may not remove ownership or license notices or represent that this License grants unrestricted, public-domain or open-source rights. Only the permissions expressly granted in Sections 2 and 3 are provided here. Separate commercial terms must be agreed in writing; silence, public access, a download or a fork does not constitute that authorization.
5. Research outputs and identification
This License does not claim ownership of Your papers, notes, data or other independent research outputs, or require them to use this License merely because You used the Software. Such outputs do not include copied Software or materials owned by others. Publication and sharing of results of Permitted Research Use are allowed, subject to the rights in the underlying research content. Acknowledging Gewu Insight and identifying the version used is appreciated.
No trademark, logo or endorsement rights are granted except identification of the Software and retention of its notices in permitted copies. No patent rights are granted by this copyright license. Rights that cannot be restricted under applicable law, and viewing/forking rights independently provided by a hosting platform's applicable terms, are not overridden by this License; those platform rights do not create a commercial-use license from the copyright holders.
6. Third-party rights
Third-party software, fonts, artwork, screenshots' underlying content, scholarly papers, data and services are governed by their own licenses, permissions and terms. See THIRD_PARTY_NOTICES.md and component-specific notices. This License neither applies its non-commercial restriction to separately licensed third-party components nor grants rights the copyright holders do not own. Access to a paper, website, font or image is not permission to redistribute it. A separate Gewu commercial license does not by itself grant third-party rights.
7. Warranty, liability and termination
To the extent permitted by applicable law, the Software is provided "AS IS", without warranties of any kind, including merchantability, fitness for a particular purpose or non-infringement. The copyright holders are not liable for claims, damages or other liability arising from use or distribution of the Software. No support, maintenance or continued access to external services is promised by this License.
The permissions granted to You terminate automatically if You breach this License. You must then stop the activities for which this License supplied permission, unless the copyright holders reinstate permission in writing. Termination does not remove third-party rights or rights under applicable law. Ownership, reserved rights, third-party protections and the warranty/liability limitations survive termination. A later license for another release does not by itself withdraw these permissions for this version while You comply with it.
