Terms of Service

Nivometra generates a site-specific estimate of the 50-year ground snow load following the federal ERDC/CRREL SR-20-1 methodology, using historical records from nearby weather stations. Coverage is limited to the lower 48 United States and Alaska, excluding states that require their own state-specific ground snow load study instead of this methodology. A report cannot be generated for a site in those states; the workspace shows which areas are affected.

A report is a software-generated statistical estimate, not a sealed or stamped engineering document. It does not constitute professional engineering advice and is not a substitute for the judgment of a licensed engineer. You are responsible for obtaining the external review and acceptance described below before relying on a result for design, construction, or permitting.

Nivometra provides software-generated statistical reference reports. We do not provide professional engineering services, structural design, site inspection, code compliance review, permit approval, construction supervision, safety certification, or stamped or sealed engineering documents.

No report, support message, email, website content, or other communication from Nivometra creates an engineer-client relationship. Nivometra is not the engineer of record for any project.

You are responsible for checking the site location, site elevation, report inputs, selected assumptions, and report output. The report depends on the information entered and the data available for the surrounding area.

Before using a report for design, permitting, construction, or any safety-related decision, you must obtain external validation from a professional engineer licensed in the relevant jurisdiction or the local authority having jurisdiction, as appropriate to the project and applicable requirements. They must determine whether the estimate and methodology are acceptable for the intended use.

Acceptance by a local authority does not replace an engineer's review, design work, or signed and sealed documents where these are required by law. You remain responsible for obtaining all required professional services and approvals. Nivometra does not perform this external validation.

A report estimates ground snow load only. It does not determine roof snow load, drift loads, sliding snow, rain-on-snow effects, exposure factors, thermal factors, importance or risk category, load combinations, structural capacity, or whether an existing or proposed structure is safe.

We do not guarantee that a building official, authority having jurisdiction, reviewer, insurer, lender, contractor, engineer, or any other person will accept a report. They may require different information, additional analysis, or a stamped or sealed engineering document.

You must have the legal capacity to enter into this agreement. If you use Nivometra on behalf of a business or other organization, you must be authorized to accept these terms on its behalf.

You must provide accurate information when you register and keep your login credentials secure. Do not share your account or allow others to use it without authorization. Tell us promptly at contact@nivometra.com if you believe your account has been used without your permission.

We may suspend or close an account that violates these terms or that we reasonably believe is being used to abuse the service.

Building and pricing a case study in the workspace is free. You pay only when you generate a report, and the price is shown before you confirm. Purchases are processed by our merchant of record, Lemon Squeezy, which is the seller of record for the transaction and handles payment, applicable taxes, and receipts. We do not store your full payment card details.

For a duplicate charge, a report that was paid for but not delivered, or another purchase problem, email us at contact@nivometra.com with the order reference and a description of the issue. Do not send full card details. We will review the purchase and the available remedy, which may include providing access to the report or arranging a refund through Lemon Squeezy. This process does not limit any refund or other remedy required by applicable law or the purchase terms presented at checkout.

A generated report is saved to your account history so you can reopen, print, or download it later. The report keeps the inputs and method used at the time it was created. If your inputs change, generate a new report.

Keep a downloaded copy of reports you need for your records. Access through your account depends on the account and service remaining available. Account deletion removes access to saved reports, subject to the retention exceptions explained in our Privacy Policy.

You agree not to:

• resell, redistribute, or sublicense reports as your own data product;
• access the service by automated means, scrape it, or attempt to overload, probe, or circumvent its security;
• misrepresent a report as a stamped or certified engineering document; or
• use the service in violation of any applicable law.

The Nivometra software, branding, and report design are ours. The report you generate may be used for your own projects and projects you undertake for clients. You may share it with the client, engineers, contractors, and reviewing authorities for those projects, provided its source, limitations, and disclaimers remain intact. This permission does not allow you to sell reports as a separate data product or misrepresent them as your own engineering work. The underlying weather-station data is sourced from public records and is not owned by us.

To the fullest extent permitted by applicable law, the service and every report are provided “as is” and “as available,” without warranties of any kind, whether express or implied, including any implied warranties of merchantability, fitness for a particular purpose, or accuracy. Snow load estimates depend on the density and quality of nearby station data and may not reflect actual conditions at your site. We do not warrant that results are error-free or suitable for any particular use.

Nothing in these terms excludes a warranty, guarantee, or remedy that cannot lawfully be excluded. Where applicable law limits an exclusion, that exclusion applies only to the extent the law allows.

To the fullest extent permitted by law, Nivometra and its officers and employees will not be liable for any indirect, incidental, consequential, or special damages arising from use of the service or a report. Subject to the exceptions below, our total liability for claims arising from a particular report will not exceed the amount you paid for that report. This report-specific cap does not set a separate limit for claims unrelated to a purchased report.

These exclusions and limits do not apply to fraud, willful misconduct, gross negligence, or any liability or remedy that cannot be excluded or limited under applicable law. They do not remove your mandatory consumer rights.

To the extent permitted by applicable law, you agree to reimburse Nivometra for reasonable losses and legal costs resulting from a third-party claim, but only to the extent caused by your unlawful use of the service, intentional misrepresentation of a report, or material breach of these terms. This obligation does not arise merely because you use a report for a project and does not cover losses caused by Nivometra's own negligence or misconduct.

We will notify you promptly of a claim for which we seek reimbursement and give you a reasonable opportunity to participate in its defense. We will not agree to a settlement that imposes an obligation on you without your consent.

We may update the service or these terms over time. If we make a material change to these terms, we will explain the change and its effective date by email or a prominent notice on the service before it applies to your future use, unless a shorter notice is required by law. Updating the date on this page alone does not establish your acceptance of a material change. Where a new agreement is required, we will ask for your acceptance before applying the revised terms to you. Changes will not retroactively remove rights you have already acquired or alter an existing dispute without your agreement.

These terms are governed by the laws of the Province of Québec, Canada, without regard to its conflict-of-laws rules, except where mandatory applicable law requires otherwise. This choice does not deprive you of consumer protections or rights to bring a claim that cannot lawfully be waived under the laws applicable to you. See our Privacy Policy for how we handle your information.
