Terms & Conditions

1. Acceptance of these terms

These Terms & Conditions ("Terms") form a binding agreement between you ("you", "your") and neuralduct ("neuralduct", "we", "us", "our") governing your access to and use of the neuralduct website, web application, tools and related services (together, the "Service").

By creating an account, clicking "I agree", or otherwise accessing or using the Service, you confirm that you have read, understood and agree to be bound by these Terms and our Privacy Policy. If you are using the Service on behalf of a business or other organisation, you represent that you are authorised to bind that organisation, and "you" refers to that organisation. If you do not agree, do not use the Service.

2. Definitions

• Account — the registered profile through which you access the Service.
• Content — any data, designs, floor plans, drawings, project files, quotes, text or other material you create, upload or generate using the Service.
• Output — duct layouts, bills of materials, compliance notes, quotes, PDFs and other results produced by the Service, including material generated with the assistance of AI.
• Subscription — a paid plan giving access to features beyond the free tier.

3. Eligibility & accounts

You must be at least 18 years old and capable of entering into a binding contract to use the Service. The Service is intended for use by HVAC and building-services professionals.

You are responsible for keeping your account credentials confidential and for all activity that occurs under your account. Notify us promptly at our support page if you suspect unauthorised access. You must provide accurate information and keep it up to date.

4. Licence to use the service

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable licence to access and use the Service for your internal business or professional purposes. This licence does not permit you to resell, sublicense, white-label or provide the Service to third parties except as expressly permitted by your plan (for example, sharing a read-only design with a client for approval).

5. Plans, billing & renewals

The Service offers a free tier and paid Subscriptions. Prices are displayed at the point of purchase and may be shown in your local currency; unless stated otherwise, amounts are in Australian Dollars (AUD) and may include or exclude GST as indicated at checkout.

• Recurring billing. Paid Subscriptions renew automatically each billing period (monthly or annual) until cancelled. By subscribing you authorise us and our payment processor to charge the applicable fee on each renewal.
• Cancellation. You may cancel at any time from your account settings. Cancellation takes effect at the end of the current paid period; you retain access until then.
• Refunds. Except where required by law (including the Australian Consumer Law — see section 15), fees already paid are non-refundable. We do not provide refunds for partial periods.
• Price changes. We may change prices for future billing periods. We will give you reasonable advance notice, and changes will not affect the period you have already paid for.
• Taxes. You are responsible for any taxes, duties or levies associated with your use, other than taxes on our income.

6. Acceptable use

You agree not to, and not to permit anyone else to:

• use the Service in breach of any applicable law, regulation or standard;
• reverse engineer, decompile, scrape, or attempt to extract the source code or underlying models of the Service, except to the extent permitted by law;
• interfere with, overload, or attempt to gain unauthorised access to the Service, its servers or networks;
• upload malware, or content that is unlawful, infringing, or that you do not have the right to upload;
• use the Service to build a competing product, or to train a competing AI model; or
• resell or commercially exploit the Service beyond your own professional use without our written consent.

7. Professional responsibility & no warranty of compliance

This is important. neuralduct is a design-assistance and estimating tool. References to standards such as ASHRAE, SMACNA, AS 4254.2, AS/NZS 3000 or any other code are provided for convenience and do not guarantee that any Output complies with those standards or with the requirements applicable to a particular project, site, jurisdiction or authority.

You are solely responsible for:

• independently verifying every design, calculation, quantity and quote before relying on it or issuing it;
• ensuring that any installed work complies with all applicable codes, standards, regulations and manufacturer specifications; and
• obtaining any required engineering sign-off, certification, permits or approvals.

The Service does not constitute professional engineering, certification, or licensed building advice, and is not a substitute for the judgement of a qualified professional.

8. AI-generated output

Parts of the Service use artificial intelligence (including third-party AI models) to detect rooms from floor plans, suggest layouts, and review designs. AI output can be incomplete, inaccurate or inconsistent. You must review and validate all AI-assisted Output before using it. We make no warranty as to the accuracy, fitness or reliability of AI-generated results, and you use them at your own risk subject to the rest of these Terms.

9. Your content & data

You retain all ownership of your Content. You grant us a worldwide, non-exclusive, royalty-free licence to host, store, process, transmit and display your Content solely to the extent necessary to operate, secure, maintain and improve the Service and to provide it to you.

You are responsible for the accuracy and legality of your Content and for maintaining your own backups of anything important to you. Our handling of personal information is described in our Privacy Policy.

10. Intellectual property

The Service, including its software, design, branding, "neuralduct" name and logo, and all underlying technology, is owned by us or our licensors and is protected by intellectual-property laws. Except for the licence expressly granted in section 4, these Terms do not transfer any rights in the Service to you. Output that you generate from your own Content may be used by you for your professional purposes, subject to these Terms.

11. Third-party services

The Service relies on third-party providers (for example, cloud hosting, authentication, payment processing and AI providers). Your use of the Service may be subject to their terms, and we are not responsible for the acts, omissions or availability of third-party services. Links to third-party sites are provided for convenience and do not imply endorsement.

12. Availability & support

We aim to keep the Service available and reliable but do not guarantee uninterrupted, error-free or secure access. The Service may be unavailable for maintenance, updates, or reasons beyond our control. Features may be added, changed or removed over time. Support is provided on a reasonable-efforts basis via our support page.

13. Disclaimers

To the maximum extent permitted by law, and subject to section 15, the Service and all Output are provided "as is" and "as available", without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement. We do not warrant that the Service will meet your requirements or that any Output will be accurate, compliant, complete or error-free.

14. Limitation of liability

To the maximum extent permitted by law, and subject to section 15:

• we will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of profits, revenue, data, goodwill, or business opportunity, or for losses arising from defective designs, rework, project delays or non-compliance, however caused; and
• our total aggregate liability arising out of or in connection with the Service or these Terms is limited to the greater of (a) the total fees you paid to us in the twelve (12) months before the event giving rise to the liability, or (b) AUD $100.

15. Australian Consumer Law

Nothing in these Terms excludes, restricts or modifies any consumer guarantee, right or remedy conferred by the Competition and Consumer Act 2010 (Cth), including the Australian Consumer Law, or any other law that cannot lawfully be excluded. Where our liability for breach of such a guarantee cannot be excluded but can be limited, our liability is limited, at our option, to re-supplying the relevant services or paying the cost of having them re-supplied.

16. Indemnity

To the extent permitted by law, you agree to indemnify and hold us harmless from any claims, liabilities, damages, losses and reasonable costs arising out of your Content, your use of the Service in breach of these Terms, your breach of any law, or your reliance on Output without independent verification.

17. Suspension & termination

You may stop using the Service and close your account at any time. We may suspend or terminate your access if you breach these Terms, if required by law, or to protect the Service or other users. On termination, your right to use the Service ends. Sections that by their nature should survive (including sections 9–10 and 13–19) will survive termination. We will handle any retained data in accordance with our Privacy Policy.

18. Changes to these terms

We may update these Terms from time to time. If we make material changes, we will take reasonable steps to notify you (for example, by posting a notice in the Service or updating the "Last updated" date above). Your continued use of the Service after changes take effect constitutes acceptance of the revised Terms.

19. Governing law

These Terms are governed by the laws of the State of Victoria, Australia, and you and we submit to the non-exclusive jurisdiction of the courts of that State and the courts competent to hear appeals from them. If any provision is found to be unenforceable, the remaining provisions continue in full force.
