Terms & disclaimer
Terms of use
Effective date: July 23, 2026
Educational estimates
The calculators and articles provide general educational estimates. They do not constitute accounting, tax, legal, engineering, product-safety, or investment advice. Results depend entirely on user-provided values and simplified assumptions.
Your responsibility
You are responsible for checking inputs, formulas, local costs, taxes, platform rules, material suitability, and safety requirements before using a result in a quote, purchase, production commitment, or customer promise.
No warranty
The site is provided on an “as is” and “as available” basis without warranties of accuracy, completeness, availability, fitness for a particular purpose, or uninterrupted operation. We may update, remove, or correct content without notice.
Acceptable use
You may use calculator results for your own personal or commercial planning. You may not disrupt the site, bypass access controls, present the site as your own service, or reproduce substantial content without permission.
Third-party services
Links, analytics, hosting, and advertising services may have their own terms and privacy practices. A link does not imply endorsement, and we are not responsible for third-party content or availability.
Changes
Material changes will be reflected by a new effective date on this page. Continued use after an update indicates acceptance of the revised terms.
