Acceptance

By using Calc for Trades, you agree to these terms. If you do not agree, do not use the website or rely on its outputs.

Estimates, not professional services

Calculator results are informational estimates based on the measurements, assumptions and formulas shown. Calc for Trades does not provide engineering, architectural, electrical, legal or other professional services.

Your responsibility

You are responsible for checking measurements, project conditions, manufacturer instructions, permits, current codes and professional requirements before purchasing materials or beginning work. Electrical and structural decisions should be verified by a qualified professional.

Permitted use

You may use the calculators for personal or legitimate business estimates. You may not misuse the service, interfere with its operation, attempt unauthorized access, or present Calc for Trades results as certified plans or approvals.

External links and services

Calc for Trades links to official code bodies, manufacturers and reference websites. An external link does not mean that Calc for Trades endorses, guarantees or controls that third-party product, service or website. Third-party services operate under their own terms and privacy policies.

Intellectual property

The Calc for Trades name, visual design, original page content and calculator presentation may not be copied, republished or misrepresented as another service. Ordinary use of calculated results for your own projects is permitted.

Availability and changes

The website may change, pause or remove features without notice. We do not promise uninterrupted availability or that every calculation will suit every project condition.

Disclaimer and limitation

To the extent permitted by applicable law, Calc for Trades is provided without warranties and is not responsible for losses arising from inaccurate inputs, reliance on estimates, code differences, site conditions, material variation, third-party services or service interruption.
