Terms of Service

These Terms of Service ("Terms") govern access to and use of the Simulations4All website, hosted simulations, calculators, courses, SimLab, AI Tutor, professional tools, and related online services (collectively, the "Service"). The Service is operated by Simulations4All, Calgary, Alberta, Canada ("Simulations4All," "we," "us," or "our").

By accessing or using the Service, creating an account, or clicking to accept these Terms, you agree to be bound by them. If you use the Service for an organization, you represent that you have authority to bind that organization, and "you" includes that organization. If you do not agree, do not use the Service.

1. The Service

Simulations4All provides interactive educational content and computational tools for exploration, calculation, analysis, estimation, and decision support. Features may be free, subject to fair-use limits, or offered under a paid order or licence. We may also provide custom development, deployment, integration, or support under a separate statement of work or other written agreement.

We may add, change, suspend, or discontinue features. We do not promise that every feature, simulation, solver, price, or planned product will remain available.

2. Eligibility and accounts

You must be legally capable of entering into these Terms. The current self-service registration form does not ask for age and does not provide a separate parent, legal-guardian, or educational-institution acceptance process. If you cannot agree on your own behalf, do not create an account through that form; a responsible adult or institution should contact us before account creation if an account is required. Account-free educational content may be used under supervision where lawful. We do not treat the ordinary registration checkbox as proof of guardian or institution authorization. Some features require an account. You must provide accurate information, protect your credentials, and promptly tell us about suspected unauthorized access. You are responsible for activity through your account except to the extent caused by our breach of these Terms or applicable law.

3. Licences and permitted use

3.1 Personal and educational use

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, and revocable licence to access and use the hosted Service for your own personal, non-commercial educational, or non-commercial evaluation purposes.

3.2 Classroom use

Educators and learners may use the hosted Service in bona fide classroom instruction and may share links to Service pages. This permission does not cover corporate or employee training, paid consulting, a separately sold course or training product, institution-wide deployment, or embedding the Service in another platform. Those uses require our written permission or a Commercial Order.

3.3 Commercial Use requires a Commercial Order

"Commercial Use" means use of the proprietary Service or its Outputs in connection with a business, profession, revenue-generating activity, internal operation, or another activity intended to obtain a direct or indirect commercial or organizational benefit. Organizational status, access to a free feature, the absence of a separate charge, or the absence of immediate revenue does not by itself make an organizational use non-commercial.

Commercial Use includes:

• employee, workforce, or contractor education or training, including internal learning programs;
• internal research or non-production development or evaluation of analytical methods, calculation methods, or procedures;
• generating, copying, or incorporating Outputs, charts, images, or screenshots in internal standard operating procedure (SOP) drafts, procedures, training materials, documentation, reports, or presentations;
• consulting or client work, client deliverables, external training, or work for an affiliate or another organization;
• production analysis, internal operations, product or service development, quality or regulatory work, or use in a product or service supplied to others; and
• organization-wide access, shared deployments, embedding, automated access, API use, white-labelling, redistribution, resale, or hosting for others.

Except for rights granted under a Separate Software Licence or an evaluation we expressly authorize, Commercial Use requires a separate Business, Enterprise, OEM, Cloud, or other written commercial order or licence accepted by both parties (a "Commercial Order").

Personal study and bona fide classroom instruction remain governed by sections 3.1 and 3.2. Merely sharing a link to a publicly available Service page does not, by itself, grant permission to copy, incorporate, distribute, or commercially use the Service, Content, or Outputs. If the intended use may fall into a category above, contact us before beginning that use and describe the expected users, tools, audience, workflow, and reuse of Outputs.

A quote, licence enquiry, payment, invoice, or access to a free feature does not by itself grant commercial, redistribution, embedding, hosting, API, OEM, or resale rights. A Commercial Order must identify the applicable product or Service, scope of use, users or deployment, term, fees, and any additional rights. If a Commercial Order conflicts with these Terms, the Commercial Order controls for its subject matter.

3.4 Purpose and limits of a Commercial Order

The purpose of a Commercial Order is to turn a described organizational use that is not included in the personal, classroom, or evaluation permissions into a defined, reviewable licence. It records what part of the Service may be used, by whom, for what purpose, and whether specified Outputs or excerpts may be reproduced in organizational materials. It does not transfer ownership of the Service or Content, sell the underlying intellectual property, certify a method or Output, or grant any right that is not expressly stated.

Where expressly included, an internal-use Commercial Order may permit authorized users to:

• access and use identified hosted simulations and tools;
• use them for internal employee education and training, internal learning or research, and non-production development or evaluation of analytical or calculation methods;
• generate calculations, results, charts, images, and other Outputs; and
• reproduce reasonable screenshots, Outputs, or excerpts in internal SOP drafts, training materials, documentation, reports, and presentations for the approved internal purpose.

Unless a Commercial Order expressly says otherwise, it does not include source code, downloadable or on-premises software, API or automated access, scraping or bulk copying, embedding, white-labelling, sublicensing, resale, public or external distribution, external training, client deliverables, marketing use, or use in a product or service supplied to another party. Sensitive-data and High-Risk Use restrictions continue to apply. A customer must obtain written permission before expanding the users, tools, audience, data, delivery method, or purpose beyond the approved scope.

3.5 Business evaluation

Where we label a feature or licence as a trial or authorize an evaluation in writing, an organization may use it internally and only for the stated evaluation period and limits to decide whether to purchase. Evaluation rights do not permit production use, live operations, employee training, client deliverables, redistribution, or incorporation into a product or service.

3.6 Separate Software Licences

Certain source code, downloadable software, WebAssembly modules, solver components, and third-party materials may be offered under an open-source, source-available, or other separate licence displayed with that component (a "Separate Software Licence"). The Separate Software Licence, not these Terms, governs your use, modification, and distribution of that component to the extent of a conflict. These Terms do not restrict rights expressly granted by a Separate Software Licence.

4. Restrictions and acceptable use

Except where a Commercial Order, Separate Software Licence, or mandatory law expressly permits it, you must not, and must not enable anyone else to:

• copy, modify, redistribute, resell, rent, lease, sublicense, or host the Service;
• embed or expose the Service through another website, application, API, or service;
• use the Service or Content to build or offer a competing product or service;
• scrape, harvest, bulk-download, or use automated means to access the Service, except a standards-compliant public search-engine crawler that follows our published crawler controls;
• reverse engineer, decompile, disassemble, derive source code from, or circumvent a technical, access, licence, security, or fair-use control;
• remove or obscure copyright, trademark, attribution, or proprietary notices;
• probe, disrupt, overload, interfere with, or gain unauthorized access to the Service or another user's account or data;
• use the Service unlawfully, deceptively, to harm or exploit others, or to infringe rights;
• use our Content to train, fine-tune, evaluate, or supply datasets for an AI or machine-learning model without a Commercial Order that expressly permits that use.

5. Inputs, Outputs, and attribution

"Inputs" are data, prompts, files, parameters, code, or other material you submit to a feature. "Outputs" are calculations, results, values, charts, reports, images, or other material generated through the Service.

As between you and us, you retain rights you already have in your Inputs. You grant us only the rights reasonably necessary to process Inputs to provide, secure, and support the Service, subject to our Privacy Policy. Features that run locally in your browser may not transmit the substance of Inputs to us. You must have all rights and permissions needed for your Inputs and must not submit personal, confidential, regulated, export-controlled, or sensitive data unless a Commercial Order expressly permits it and appropriate safeguards are in place.

You may use Outputs only for a purpose permitted under section 3. To the extent an Output incorporates our protected Content, that Content remains ours or our licensors'. Commercial Use—including reproducing or incorporating Outputs or screenshots in internal SOPs, workforce training materials, or other business documentation—plus redistribution, resale, public marketing use, or embedding of Outputs requires a Commercial Order that expressly covers that use. You are responsible for reviewing and verifying every Output. You must retain notices, citations, and source attribution included with an Output and must not falsely imply our endorsement or certification.

6. Intellectual property and feedback

The proprietary Service and its software, simulations, algorithms, text, graphics, design, compilation, and trademarks (collectively, "Content") are owned by Simulations4All or its licensors and are protected by applicable law. Except for the limited rights expressly granted in these Terms, a Commercial Order, or a Separate Software Licence, no rights are transferred to you.

If you voluntarily provide feedback or suggestions, you grant us a worldwide, perpetual, irrevocable, royalty-free right to use them without restriction or compensation, provided we do not publicly identify you as the source without permission.

7. Fees, taxes, subscriptions, and custom work

Fees, currency, taxes, payment schedule, licence metrics, renewal, cancellation, refunds, support, and delivery terms for a paid offering are set out in the applicable Commercial Order. Unless it says otherwise, fees exclude applicable taxes, duties, and levies. Custom development begins only under an agreed statement of work. No intellectual-property ownership in custom work transfers unless a signed agreement expressly says so.

8. Third-party services and components

The Service may link to, interoperate with, or include content, software, models, data, or services from third parties. Third-party terms and licences may apply. We do not control third-party sites or services and are not responsible for their availability, content, or practices. References and links do not imply endorsement.

11. Disclaimer of warranties

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE, CONTENT, AND OUTPUTS ARE PROVIDED "AS IS," "AS AVAILABLE," AND WITH ALL FAULTS. WE DISCLAIM ALL WARRANTIES, CONDITIONS, AND REPRESENTATIONS, EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING MERCHANTABILITY, MERCHANTABLE QUALITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, TITLE, NON-INFRINGEMENT, QUIET ENJOYMENT, AND WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

We do not warrant that the Service or Outputs will be accurate, complete, current, uninterrupted, error-free, secure, or suitable for your requirements. A Commercial Order may state different express warranties for the offering it covers.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, SIMULATIONS4ALL AND ITS PERSONNEL, AFFILIATES, AND LICENSORS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA, GOODWILL, ANTICIPATED SAVINGS, BUSINESS INTERRUPTION, PRODUCT RECALL OR REMEDIATION, OR REGULATORY FINES OR PENALTIES, ARISING UNDER ANY THEORY OF LIABILITY, EVEN IF ADVISED OF THEIR POSSIBILITY.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE FEES YOU PAID US FOR THE AFFECTED SERVICE DURING THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) CAD $100.

If a Commercial Order applies, its liability terms control for that Commercial Order. The exclusions and cap apply collectively and regardless of the number of claims. Nothing in these Terms excludes or limits liability to the extent it cannot lawfully be excluded or limited. Any unenforceable exclusion or limitation will be read down to the minimum extent necessary.

13. Your responsibility

You are responsible for your Inputs, your configuration and interpretation of the Service, your verification and use of Outputs, and decisions or actions you take based on them. Educators are responsible for age-appropriate selection and supervision. Nothing on the Service is an approval, certification, or endorsement of your work, product, design, or compliance status.

14. Indemnity

To the maximum extent permitted by law, if you use the Service on behalf of an organization or for Commercial Use, you and that organization will defend, indemnify, and hold harmless Simulations4All and its personnel from third-party claims, damages, losses, liabilities, costs, and reasonable legal fees arising from (a) your Inputs; (b) your unauthorized High-Risk Use, redistribution, embedding, or Commercial Use; (c) your breach of these Terms or applicable law; or (d) your infringement of a third party's rights. This does not apply to the extent a claim results from our fraud, wilful misconduct, or liability that cannot be excluded by law. We will provide reasonable notice and cooperation, and you may not settle a claim in a way that admits our fault or imposes an obligation on us without our written consent.

15. Privacy

Our Privacy Policy explains how we handle personal information. Our Cookie Policy explains our use of cookies and similar technologies. Where permitted, audience measurement may operate by default to help us understand use and reliability. We apply restrictive Google consent defaults for the EEA, United Kingdom, and Switzerland, keep advertising consent signals denied until advertising is explicitly enabled, and provide browser-level privacy settings in those policies. A Commercial Order may include additional data-processing terms.

16. Suspension and termination

We may suspend or terminate access if you materially breach these Terms, fail to pay an amount when due, create security or legal risk, or use the Service in a way that could cause harm or liability. Where reasonably practicable, we will give notice and an opportunity to cure. We may act immediately where necessary to protect users, the Service, or third parties. You may stop using the Service at any time. Terms that by their nature should survive will survive, including sections 3 through 6 and 9 through 20.

17. Changes

We may update these Terms to reflect changes in the Service, law, or our practices. We will post the revised Terms and update the date above. If required by law, or if a change materially reduces existing rights, we will provide additional notice and obtain consent where required. Changes do not retroactively modify a Commercial Order unless that order permits it. Continued use after the effective date means you accept the revised Terms to the extent permitted by law.

18. Governing law and disputes

These Terms are governed by the laws of the Province of Alberta and the federal laws of Canada applicable there, without regard to conflict-of-laws principles. Subject to mandatory law, the courts located in Calgary, Alberta have exclusive jurisdiction over disputes arising from these Terms or the Service. The United Nations Convention on Contracts for the International Sale of Goods does not apply. This section does not deprive a consumer of mandatory protections or a forum that cannot lawfully be waived in the consumer's place of residence.

19. General

These Terms, the policies they incorporate, any applicable Separate Software Licence, and any Commercial Order form the entire agreement for their subject matter. You may not assign these Terms without our written consent; we may assign them in connection with a reorganization, merger, financing, or transfer of the Service. Failure to enforce a provision is not a waiver. If a provision is unenforceable, it will be read down or severed and the remainder will continue. We are not liable for delay or failure caused by events beyond our reasonable control. Headings are for convenience only. "Including" means "including without limitation."
