Last updated: July 28, 2026

These terms govern use of the BuildMath website at carpentercalc.com and the BuildMath mobile app, both operated by BuildMath.

Planning tools

The calculators, charts, diagrams, and code summaries support arithmetic and planning. They do not replace field verification, current local code, product instructions, engineering judgment, permits, inspections, or professional advice.

Your responsibility

You are responsible for checking every input, unit, result, material specification, site condition, connection, load path, and governing requirement before ordering, cutting, or building.

Intellectual property

The website, app, design, branding, original text, and code belong to BuildMath or its licensors. Reference facts and linked standards remain subject to their respective owners and licenses.

BuildMath purchases

Apple processes App Store transactions. Prices and refund eligibility are controlled by the storefront and applicable Apple policies.

No warranty

The website and app are provided as available to the extent permitted by law. Construction conditions vary, and no calculator can account for every project fact.
