1 Acceptance of these Terms
iStruct2D (the “App”) is provided to you subject to these Terms & Conditions. By downloading, installing or using the App you agree to be bound by them. If you do not agree, please do not use the App.
The agreement that governs your use of iStruct2D. In plain language: it's a learning and reference tool — always verify results and apply your own engineering judgement.
iStruct2D (the “App”) is provided to you subject to these Terms & Conditions. By downloading, installing or using the App you agree to be bound by them. If you do not agree, please do not use the App.
The App is a 2D structural-analysis sketchpad intended for learning, exploration and preliminary reference only. It is not a substitute for a qualified structural engineer, accredited design software, or compliance with any building code or standard. It is currently provided in beta.
Nothing produced by the App constitutes engineering, design or professional advice. Any results — reactions, internal forces, deflections or otherwise — must be independently verified by a competent person before being relied upon for any design, construction or other real-world decision.
You are solely responsible for the models you create, the inputs you provide, the interpretation of any results, and any decision made using the App. Always apply your own engineering judgement.
The App is provided “as is” and “as available”, without warranties of any kind, express or implied, including fitness for a particular purpose, accuracy, or uninterrupted or error-free operation. Calculations may contain errors or limitations.
To the maximum extent permitted by law, the developers and The University of Queensland shall not be liable for any direct, indirect, incidental, consequential or special loss or damage arising from the use of, or inability to use, the App or its results. Nothing in these Terms excludes rights that cannot be excluded under applicable law.
Projects you create are stored locally on your device. You are responsible for backing up your work, and exported project files are shared only when you choose to share them. How information is handled is described in full in our Privacy Policy.
iStruct2D is independently owned and developed by Weng Chong LAO (the “Developer”). The App is 100% owned by the Developer, who retains all right, title and interest in it — including its source code, solver, design, user interface, diagrams, branding and content — except for third-party materials used under licence. © 2026 Weng Chong LAO. All rights reserved.
These Terms grant you a personal, limited, non-exclusive, non-transferable and revocable licence to use the App for its intended educational and reference purposes. You may not copy, modify, reverse-engineer, decompile, redistribute, resell or create derivative works from the App or its content, except as permitted by law or with the Developer's written permission.
iStruct2D was co-developed in collaboration with The University of Queensland (“UQ”), School of Civil Engineering. This collaboration informed the engineering and educational design of the App. For the avoidance of doubt, the collaboration does not transfer ownership: the App remains 100% owned by the Developer, Weng Chong LAO.
“The University of Queensland”, “UQ” and related names and marks are the property of The University of Queensland and are used with acknowledgement of the co-development collaboration. Nothing in these Terms grants you any right to use UQ's or the Developer's names, logos or marks.
For questions about these Terms, support, feedback, or partnership and licensing enquiries, you can reach the Developer, Weng Chong LAO, on LinkedIn. Further ways to get in touch are on our Support page.
These Terms may be updated from time to time. Continued use of the App after changes take effect constitutes acceptance of the revised Terms.
These Terms are governed by the laws of Queensland, Australia, without regard to conflict-of-law principles.
