Terms and Conditions & Software Disclaimer

Version 1.1-beta  |  Effective: 29 September 2026  |  Governing law: New South Wales, Australia

1. Acceptance of Terms

By registering for, accessing, or using HydraulicSim (the "Software"), you ("User") agree to be bound by these Terms and Conditions ("Terms"). If you do not agree to these Terms, you must not use the Software.

These Terms constitute a legally binding agreement between you and the operator of HydraulicSim ("we", "us", "our"). These Terms are governed by and construed in accordance with the laws of New South Wales, Australia and the Commonwealth of Australia, including the Competition and Consumer Act 2010 (Cth) and its Schedule 2 (Australian Consumer Law).

2. Engineering Disclaimer — Critical Notice

HydraulicSim is an educational and preliminary-analysis tool only. It is designed to assist with exploratory hydraulic and water-hammer modelling. Results are indicative only and are subject to the assumptions, simplifications, and limitations of the underlying numerical methods.

In particular, the Software must not be used for:

• Final engineering design of water supply, wastewater, or pipeline systems;
• Structural, safety, or pressure-rating assessments of physical assets;
• Regulatory compliance submissions without independent professional verification;
• Emergency response planning as a primary decision tool;
• Any purpose where an error in the results could cause harm to persons, property, or the environment.

Users are strongly advised to engage a suitably qualified and registered professional engineer to verify any results before relying on them for design or operational decisions.

3. Limitation of Liability

To the extent permitted by applicable Australian law (including the Australian Consumer Law), we exclude all liability for:

• Any loss, damage, cost, or expense (whether direct, indirect, special, incidental, or consequential) arising from your use of, or reliance on, the Software or its results;
• Any inaccuracy, error, or omission in simulation outputs;
• Loss of data, business interruption, or loss of profits;
• Any harm arising from decisions made based on Software outputs.

Nothing in these Terms excludes, restricts, or modifies any guarantee, right, or remedy conferred by the Australian Consumer Law that cannot be excluded, restricted, or modified by agreement. Where liability cannot be excluded but can be limited under the Australian Consumer Law, our liability is limited to, at our election: (a) re-supplying the Software; or (b) the cost of re-supplying the Software, which during the beta period is nil (AUD $0).

Nothing in these Terms limits or excludes liability for death or personal injury caused by negligence, or for fraud or fraudulent misrepresentation.

4. No Warranty

To the fullest extent permitted by law, the Software is provided "as is" and "as available" without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, completeness, or non-infringement.

We do not warrant that the Software will be error-free, uninterrupted, or that any defects will be corrected. As beta software, it may be modified, suspended, or discontinued at any time without notice.

5. User Responsibilities

You agree that you will:

• Use the Software only for lawful purposes and in accordance with these Terms;
• Not attempt to reverse-engineer, decompile, or extract proprietary components of the simulation engine;
• Not use the Software to process data that you are not authorised to process;
• Take sole responsibility for verifying the suitability of simulation results for your intended application;
• Maintain the security of your account credentials and not share your password.

6. Intellectual Property

All intellectual property rights in the Software, including the simulation engine, user interface, documentation, and underlying source code, are owned by or licensed to us. These Terms do not transfer any ownership of intellectual property to you. You are granted a limited, non-exclusive, non-transferable, revocable licence to use the Software for its intended purpose during the term of these Terms.

Simulation results that you generate using the Software belong to you, subject to the disclaimer in clause 2.

7. Privacy

We collect your name and email address for account management purposes. We handle personal information in accordance with the Privacy Act 1988 (Cth) and the Australian Privacy Principles. We do not sell or share your personal information with third parties for marketing. Your authored data is processed in your browser and, for cloud features, by our hosting infrastructure. Transactional email and optional external services involve service providers. See our Privacy notice for the current data-handling description.

8. Account Termination

We reserve the right to suspend or terminate your account if you breach these Terms, engage in fraudulent activity, or use the Software in a way that is harmful to others or to our systems. You may close your account at any time by contacting us.

9. Changes to These Terms

We may update these Terms from time to time. If we make material changes, we will notify you by email or by displaying a notice within the Software. Your continued use of the Software after such notice constitutes your acceptance of the updated Terms. If you do not agree, you must stop using the Software.

10. Governing Law and Dispute Resolution

These Terms are governed by the laws of New South Wales, Australia. Any dispute arising from these Terms that cannot be resolved informally will be submitted to the exclusive jurisdiction of the courts of New South Wales. Nothing in this clause prevents either party from seeking urgent injunctive or equitable relief.
