Website and procurement inquiry terms.
These Terms of Service describe how visitors may use this website and how calculator procurement inquiries are handled. By accessing the website, browsing product information, submitting an RFQ, or requesting documentation, you agree to use the site for lawful business purposes and to provide accurate information when you ask our team to respond. The website is intended for institutional buyers, schools, corporate purchasing teams, distributors, resellers, and other professional users evaluating calculator programs. It is not designed as a consumer checkout system and does not create a binding sale by itself.
Information on this website
Product descriptions, model references, documentation notes, service descriptions, and procurement guidance are provided for general evaluation. Calculator availability, specifications, packaging, compliance documentation, accessories, lead times, and pricing may change. A formal quote, written confirmation, or executed purchase agreement is required before any supply commitment exists. If a buyer requires a specific document, market declaration, exam-policy confirmation, or packaging condition, that requirement must be stated in the inquiry or purchase documentation so it can be reviewed before acceptance.
Quote requests and buyer responsibilities
When you submit a quote request, you are responsible for providing accurate quantities, delivery regions, required dates, model preferences, institutional constraints, and documentation needs. Our response may include questions, substitutions, assumptions, or recommended review steps. Those responses are intended to help your organization evaluate a calculator program. You remain responsible for final approval, legal review, public tender compliance, curriculum acceptance, professional exam suitability, reseller commitments, import requirements, and any internal purchasing rules that apply to your organization.
Acceptable use
You may not use the website to submit false information, interfere with site operation, attempt unauthorized access, copy content for misleading commercial use, or represent that a quote has been accepted before written confirmation. You may not use forms to transmit harmful code, abusive material, or unrelated promotions. We may decline, delay, or ignore inquiries that appear incomplete, fraudulent, automated, or outside the intended B2B procurement scope.
Third-party references
The site may refer to calculator categories, technical documents, compliance concepts, institutions, or external services for explanatory purposes. Such references do not create an endorsement unless expressly stated in a written agreement. Buyers should independently verify official requirements, approved calculator lists, and regional compliance obligations before relying on any model for a regulated or exam-sensitive program.
Limitation of liability
The website is provided on an informational basis. To the fullest extent permitted by law, we are not liable for indirect, incidental, consequential, special, or punitive damages arising from website use, delayed responses, unavailable products, changed specifications, or a buyer's reliance on preliminary information. Any confirmed transaction will be governed by the written terms attached to that transaction, including applicable quotation, invoice, or supply agreement terms.
Changes to these terms
We may update these Terms of Service when the website, service model, or procurement workflow changes. The updated version will apply once posted. Continued use of the website after an update means you accept the revised terms. If your organization needs a signed commercial agreement, these website terms do not replace that document.
