Terms of Use

Using the calculators

RoxyCalc provides online arithmetic tools for early material planning. You may use the pages for personal, educational, trade, estimating, and project-planning purposes, provided that you check the result against the actual product and job before relying on it.

You are responsible for entering measurements in the selected units, selecting the correct product coverage or yield, choosing a sensible waste allowance, and checking the final result. A calculator cannot see the job site, confirm a product label, or know every local requirement.

Planning estimates only

RoxyCalc results are estimates. They are not structural engineering, architectural documentation, permit advice, licensed trade advice, safety certification, or a substitute for manufacturer instructions. Confirm final quantities and installation methods with product documentation, supplier guidance, site conditions, local code requirements, drawings, and qualified professionals where appropriate.

Extra care is required for structural work, retaining systems, foundations, fire-rated assemblies, wet areas, waterproofing, electrical or gas work, roofing, drainage, and any project where a quantity error could create a safety or compliance problem.

Products, prices, and external services

Optional price fields are user-provided rough inputs. RoxyCalc does not promise that a price, pack size, bag yield, coverage figure, or supplier unit remains current. Product availability, batch differences, delivery limits, and local currency can change the purchase decision.

The site may use third-party analytics or advertising services. Those services have their own terms and privacy policies, and their availability does not change the calculation logic. See the privacy policy for the current disclosure.

Feedback and acceptable use

Use the contact page to report calculation issues, unclear labels, accessibility problems, or broken links. Do not send payment details, identity documents, private project files, or other sensitive personal information. Do not attempt to disrupt the site or bypass access controls, and do not use the calculators to make a high-consequence decision without appropriate professional review.

Changes

RoxyCalc may update calculator formulas, explanations, navigation, or these terms as the site is maintained. The page date and the current calculator guidance should be checked when a result matters to a purchase or installation.
