Terms

Effective July 19, 2026

By using drywallcalculator.app you agree to these terms.

The service

drywallcalculator.app provides a free, browser-based drywall material and cost calculator. It is offered "as is" and "as available", without warranties of any kind, express or implied.

Estimates only

All quantities and costs are approximate planning estimates based on common residential conventions and the prices you enter. They are not a substitute for manufacturer coverage figures, local building codes, a permit review, or professional advice. Always verify materials against your supplier and local authority before purchasing or building. Do not rely on this tool for anything where an error could cause injury or financial loss.

Liability

To the maximum extent permitted by law, the operator of drywallcalculator.app is not liable for any damages arising from the use of, or inability to use, this site, including over- or under-ordering materials.

Intellectual property

The design, text, and code of this site belong to the site operator. You may link to any page freely.

Privacy

drywallcalculator.app is a free online drywall calculator. It is built to know as little about you as possible.

What we collect

Nothing, directly. There are no accounts, no sign-up forms, no advertising, no analytics scripts, and no cookies set by this site. We never see the room dimensions, prices, or anything else you type into the calculator.

What stays in your browser

Your last-used inputs and theme are saved with your browser's localStorage so the calculator reopens the way you left it, and your estimate can also be encoded into a shareable link that only exists if you choose to copy it. This data never leaves your device unless you share that link yourself, and you can erase it at any time by clearing site data in your browser settings.

Hosting

The site is served by Cloudflare's network. Like any web host, Cloudflare processes basic connection data (such as IP addresses) in server logs to deliver the site and protect it from abuse. See Cloudflare's privacy policy for details. We do not receive or store these logs ourselves.

Accuracy

The material counts and costs are estimates to help you plan and shop. They are not engineering or code-compliance advice; confirm quantities, fire ratings, and local building-code requirements with your supplier, permit office, or a qualified professional before you build.

Changes and contact

These terms and the privacy information may be updated from time to time; the current version always lives at this address. Questions can be sent to the site operator via the contact details on the domain's public WHOIS record.
