Terms of Use

Acceptance

By using BuildNumeris you agree to these terms as they apply to the public website and its calculators. If you do not agree, the intended course is simply not to use the site. The terms are written to be readable, because a terms page that nobody reads protects nobody.

Permitted use

You may use the public tools for lawful personal, educational, estimating and general informational purposes, including commercial estimating work, and you may keep and use the results you calculate. You may not interfere with site operation, attempt to bypass hosting or security controls, submit abusive volumes of automated requests, scrape the site for redistribution, or use the forms for spam or unlawful communication.

Calculator results

Results are generated from your inputs and the published formulas. They are planning estimates — not warranties, guarantees, quotations or project specifications. The disclaimer page describes the technical limitations in detail, and it is incorporated into these terms by reference. You remain responsible for verifying measurements, units, product data, prices and applicable regulatory requirements before relying on any figure.

Content and branding

BuildNumeris's original page text, interface design, logo mark, tagline, code and overall compilation are protected to the extent provided by applicable law. Ordinary use of calculated results for your own projects is unrestricted. Copying the site's original content, styling or code for redistribution, resale or a competing service is not permitted without written permission. Brief quotation with attribution, such as citing a formula in project documentation, is fine.

Trademarks and third-party information

Product names, standards and external resources may be referenced descriptively; they remain the property of their owners. Where a calculator refers to manufacturer information, the manufacturer's current documentation governs the actual value, and users should verify important figures at the source.

Availability

BuildNumeris may update, remove or temporarily disable calculators, pages or features at any time. Formulas may be corrected, construction practices and product specifications change, and no specific page or tool is guaranteed to remain available in its present form. Hosting interruptions outside the site's control may also occur.

Accuracy and corrections

The site treats arithmetic accuracy as its core obligation: confirmed formula errors are corrected promptly and noted. However, given the variability of construction inputs, no representation is made that results will match any particular project outcome. If you believe a calculation is wrong, the contact page describes exactly what to include in a reproducible report.

Limitation of liability

To the maximum extent permitted by law, BuildNumeris is not liable for damages arising from use of the site or reliance on its results, including material overages or shortages, schedule impacts, or costs of corrections. The tools are provided for estimation support with all verification responsibilities stated on each page, and the practical remedy for any defect is correction of the page, not damages.

Professional decisions

The site is not a professional engineering, architectural, surveying or construction advisory service, and using it does not create any professional relationship. Safety-critical and regulated decisions must be made using appropriate project documents and qualified professionals, as the disclaimer page elaborates.

Changes to these terms

These terms may be updated as the site evolves; material changes should be reflected on this page. Continued use after changes constitutes acceptance of the updated terms.

Your calculations remain yours

The dimensions, prices and results you enter and generate belong to your project; the site claims no interest in them and, because everything runs locally, never even sees them. Publishing a page of your own estimate that was produced with these tools is your work product and your decision.

Linking to BuildNumeris

Linking to any public page from documentation, course material, forums or project correspondence is welcome and needs no permission, provided the link does not imply endorsement of a product, contractor or supplier. Deep links directly to calculators are stable by design, since page addresses follow the tool names.

Acceptable messages

Communications through the contact form must be lawful and civil, free of spam, malicious content and unsolicited bulk messaging, and must not include confidential third-party documents. The site reserves the right to disregard messages that abuse these expectations.

Severability and governing considerations

If any clause of these terms is held unenforceable in a given jurisdiction, the remainder continues to apply. Nothing here is intended to create mandatory arbitration, waive consumer protections that cannot be waived, or override mandatory local law where it applies to a visitor.

Updates and continued use

The terms may be revised as the site changes; material revisions will be reflected on this page. Continuing to use the site after a revision constitutes acceptance of the updated terms, and the revision date should be treated as the date of the page you are reading.

Interoperability and technical expectations

The site is built as standard HTML, CSS and browser JavaScript with no plugins, no app installation and no specific vendor required. Features depend on a reasonably current browser with JavaScript enabled; content pages remain readable without it, though the calculate buttons will not run. No guarantee is made of uninterrupted availability, and updates may occasionally change page addresses, although calculator addresses are kept stable wherever possible.

No endorsement of third parties

Mentioning a material, product category, standard or trade practice does not endorse any manufacturer, supplier, contractor or tool. The site accepts no sponsored placements in its calculators, and any future sponsorship will be labeled as such directly where it appears.

One more practical note

These terms exist to keep expectations honest, not to trap anyone: the calculators are free, they run on your device, and their method is printed on every page. Use them widely, check them against your own arithmetic, and send corrections when you find them — that exchange makes the tools better for every visitor.

Questions about these terms can be sent through the contact page, which also explains what information a useful message includes. Term-related questions are answered as website matters, not as legal advice.
