Terms of Service

HIRVA Consultancy Inc. is a corporation registered in Ontario, Canada. We build and operate SimNode, a browser-based factory design and discrete-event simulation platform, along with related engineering services. You can reach us at info@hirva.ca.

• You must provide an accurate email address and keep your account details current.
• You are responsible for keeping your password confidential and for all activity under your account.
• Accounts are for a single user. Sharing one account across a team is not permitted; contact us for team or enterprise arrangements.
• Tell us promptly at info@hirva.ca if you believe your account has been accessed without authorisation.

SimNode offers a free tier with limited capacity, and every new account begins with a 14-day trial of Pro features. No payment card is required for the trial. The trial is available once per account and, unless you start a paid subscription, your account simply reverts to the free tier when it ends. Nothing is charged automatically at the end of a trial.

• Paid plans are billed in advance on a monthly or annual basis and renew automatically until cancelled.
• Prices are shown in US dollars and exclude tax. Applicable taxes — including Canadian GST/HST — are calculated and added at checkout.
• Payments are processed by Stripe. By subscribing you authorise recurring charges to your chosen payment method.
• You may cancel at any time from the billing portal. Cancellation takes effect at the end of the period you have already paid for, and you keep access until then.
• If we change prices, we will give at least 30 days' notice before the change applies to your renewal.

Because the 14-day trial lets you evaluate the paid features before paying, we do not generally refund fees for periods already started, except where required by law. If something has gone genuinely wrong — a billing error, a failure on our side — email us and we will make it right.

You agree not to:

• Reverse engineer, decompile, or attempt to extract the source of the service, except where that right cannot lawfully be excluded.
• Resell, sublicense, or provide the service to third parties as your own product.
• Circumvent or attempt to circumvent plan limits, licensing checks, or export watermarks.
• Interfere with the service's operation, including by placing unreasonable load on our infrastructure or by automated scraping.
• Use the service unlawfully, or to build or operate anything intended to cause harm.

Your process models, parameters, results and any files you create remain yours. We claim no ownership of them. You grant us only the limited permission needed to operate the service for you — for example, running a simulation you requested on our servers, or generating a report you asked for.

SimNode, the HIRVA name and marks, the simulation engine, templates and documentation remain our property. A subscription grants you a limited, non-exclusive, non-transferable right to use the service while your plan is active. It does not transfer ownership of anything.

This section matters more than any other in this document. Please read it.

• SimNode produces estimates derived from the inputs, assumptions and distributions you supply. Its output is a model of a factory, not the factory.
• Results, optimisation suggestions, cost and ROI figures, and AI-generated advice are decision-support information only. They are not a professional engineering opinion, a stamped design, a safety assessment, or a substitute for site-specific analysis.
• Generated robot code and control sequences are drafts. They must be reviewed, validated and commissioned by a qualified person against the actual equipment, controls and applicable safety standards before any use on real machinery.
• You are responsible for verifying results independently before committing capital, altering a production line, or operating equipment. HIRVA is not liable for decisions taken on the basis of simulation output.

We work to keep SimNode available and reliable, but we do not offer a guaranteed uptime level on self-serve plans. We may perform maintenance, and we may add, change or withdraw features over time. If we withdraw something material to a paid plan, we will give reasonable notice.

The service is provided “as is” and “as available”. To the fullest extent permitted by law, we disclaim all implied warranties, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the service will be uninterrupted, error-free, or that results will meet your requirements.

To the fullest extent permitted by law, HIRVA will not be liable for indirect, incidental, special, consequential or punitive damages, nor for lost profits, lost production, lost data or business interruption, arising from your use of the service. Our total aggregate liability for any claim is limited to the amount you paid us in the twelve months before the event giving rise to the claim.

Nothing in these terms limits liability that cannot lawfully be limited, including liability for fraud, or any statutory consumer rights you may have.

You may stop using the service and cancel at any time. We may suspend or terminate an account for a material breach of these terms, for non-payment, or where required by law — normally after notice and an opportunity to fix the problem, unless the breach is serious. Export any work you want to keep before your access ends.

We may update these terms as the service evolves. If a change is material, we will give notice by email or in the app before it takes effect. Continuing to use the service after that means you accept the updated terms.

These terms are governed by the laws of the Province of Ontario and the federal laws of Canada that apply there. The courts of Ontario have jurisdiction, without prejudice to mandatory protections in your country of residence.
