Site terms

Agreement to these terms

The following terms set the rules for using calculator-concrete.org and the concrete calculator it provides. By using the site you agree to them; if you do not agree, please do not use it. Our Privacy Policy explains how information about visitors is handled.

What the site offers

Concrete Calculator provides a free concrete calculator that runs in your web browser, together with guides explaining how it works. You do not need an account, and there is nothing to pay. It is provided as is, for general information and convenience.

Results are estimates

Results from the concrete calculator are estimates, built from what you enter and from the assumptions described in the guides. Real-world conditions vary, and mistakes in the inputs or in the tool itself are possible.

Before relying on a result for anything important, especially costs, health or safety, check it by other means. The site does not provide engineering, medical, legal, financial or any other professional advice. Speak to a qualified professional where it matters.

Rules for using the site

You may use the site for any lawful purpose. You agree not to:

• use bots or scripts to copy the site in a way that harms its performance for others;
• reproduce substantial parts of the site, its guides or its code as your own work.
• test, probe or attack the site's security, or interfere with how it runs;
• use the site for anything unlawful, fraudulent or harmful;

Disclaimer of warranties

The site and the concrete calculator are provided “as is” and “as available”. To the extent the law allows, we disclaim all warranties, express or implied. Among other things, we make no warranty of accuracy, fitness for a particular purpose or non-infringement. We do not promise that the site will be error-free, uninterrupted or free of harmful components.

Limitation of liability

To the maximum extent permitted by law, we will not be liable for indirect or consequential loss, or for loss of profits, data or business, that arises from using calculator-concrete.org or relying on the concrete calculator. If liability cannot be excluded, it is limited as far as the law permits. These terms do not affect any liability that cannot lawfully be excluded or limited.

Third-party links and advertising

Pages on the site contain third-party ads and may contain links to external websites. Those websites and advertisers are outside our control, and we are not responsible for what they publish, sell or do with your data. Any dealings with an advertiser are solely between you and that advertiser.

Copyright and content

The site's content, layout and code are owned by its operator or licensors and protected by copyright law. You may use the results the concrete calculator gives you freely, and you are welcome to link to any page or share it. Copying or republishing substantial parts of the site, the guides or the code requires our permission. If you believe something here infringes your rights, see our DMCA page.

Suspension of access

We may block or restrict access for anyone who breaks these terms or harms the site, for example by blocking abusive traffic. Sections that are meant to last, including the disclaimers and liability limits, still apply after access ends.

Availability and changes

Parts of the site may be changed, paused or withdrawn at any time. These terms are updated when our practices change, and the version published here applies. Your continued use of the site after a change counts as acceptance.

If part of these terms is invalid

Should a court find any part of these terms invalid, the remaining parts stay in force and the invalid part is applied as far as possible. If we do not enforce a provision straight away, we have not given up the right to do so.
