License and Professional Disclaimer

Last updated: 1 October 2026

Luma ("Luma", "the Software", "we", "us") is a browser-based finite-element
analysis and reinforced-concrete slab design service. This page sets out the terms
on which you may access and use Luma, and the professional disclaimers that apply
to its output. By creating an account, signing in, or using the Software you agree
to these terms. If you do not agree, do not use Luma.

1. Licence grant

Subject to these terms and to payment of any applicable fees, Luma grants you a
limited, revocable, non-exclusive, non-transferable, non-sublicensable licence to
access and use the Software for your internal professional, commercial or
educational purposes.

2. One seat per user - no sharing

  • Each account is for a single named individual. Credentials, sessions, invite
    links, API keys and access tokens must not be shared, published, pooled or used
    by anyone other than the account holder.
  • You must not permit concurrent use of one account by multiple people, or resell,
    rent, lease, lend, sublicense, distribute or otherwise make the Software
    available to third parties.
  • Organisations may purchase multiple seats; every seat is assigned to a named
    user.
  • We may monitor concurrent sessions and suspend or terminate accounts that breach
    this section.

3. Acceptable use and restrictions

You must not:

  • copy, modify, translate, reverse engineer, decompile or disassemble the
    Software, or attempt to derive its source code, models or algorithms;
  • scrape, crawl, overload or automate access except through documented interfaces
    and within the stated rate limits;
  • use the Software to build or benchmark a competing product for publication
    without our written consent;
  • upload unlawful content, or content you do not have the right to use;
  • circumvent authentication, seat limits, quotas or other technical controls.

4. Professional engineering disclaimer

Luma is a computational tool. It is not a substitute for professional
engineering judgement.

  • All inputs, modelling assumptions, material properties, loads, combinations,
    boundary conditions, analysis methods and design checks must be independently
    reviewed and verified by a qualified, licensed structural engineer.
  • Outputs - including moments, shears, reactions, deflections, crack widths,
    punching checks, reinforcement areas and reports - are indicative and must be
    checked against hand calculations, independent software, code requirements and
    project-specific criteria before use.
  • Design codes, standards, material factors and construction practices change over
    time and vary by jurisdiction. You are responsible for confirming that the
    methods, parameters and results are appropriate for your project and location.
  • You remain solely responsible for the designs, drawings, specifications and
    construction documents you produce, and for the safety, serviceability,
    compliance and performance of the structures you design.
  • Do not rely on the Software for life-safety-critical decisions without
    independent verification and appropriate professional review.

5. No warranty

The Software is provided "as is" and "as available", without warranties of any
kind, express or implied, including merchantability, fitness for a particular
purpose, accuracy, reliability, availability, security or non-infringement. We do
not warrant that the Software will be uninterrupted or error-free, or that its
results will be accurate or suitable for any purpose.

6. Limitation of liability

To the maximum extent permitted by law, Luma and its officers, employees and
suppliers are not liable for any indirect, incidental, special, consequential or
exemplary loss, or for loss of profits, revenue, data, goodwill, projects or
opportunity, or for any claim arising from designs, analyses or decisions made
using the Software. To the extent liability cannot be excluded, our total
aggregate liability is limited to the fees you paid for the Software in the twelve
months preceding the claim. Nothing in these terms excludes rights that cannot be
excluded under applicable consumer law.

7. Indemnity

You indemnify Luma against claims, losses and costs arising from your use of the
Software, your models and data, your designs, or your breach of these terms.

8. Intellectual property

The Software, its source code, algorithms, documentation, design and branding are
owned by Luma or its licensors and are protected by copyright and other laws. No
rights are granted except as expressly stated here. Third-party and open-source
components are used under their respective licences. You retain ownership of the
models, data and content you upload; you grant us a limited licence to host,
process, transmit and back up that content solely to operate the service.

9. Availability, changes and termination

We may modify, suspend or discontinue features, impose limits, or update these
terms at any time. Material changes will be posted on this page with a revised
date. We may suspend or terminate access for breach of these terms, non-payment,
security risk or misuse. You may stop using the Software at any time and request
account deletion as described in the Privacy Policy.

10. Governing law

These terms are governed by the laws of New South Wales, Australia, and the courts
of New South Wales have exclusive jurisdiction, without regard to conflict-of-law
rules. If any provision is found unenforceable, the remaining provisions continue
in effect.
