Terms of Use

Last updated: 16 August 2026

This is a plain-language policy written by the site owner. It has not been reviewed by a lawyer.

By using CalcDome you agree to these terms. If you do not agree with them, please do not use the site.

What you get

The calculators are free to use. There is no account, no subscription and no paywall. We may add, change, or remove calculators, and may change or discontinue the site at any time without notice.

No warranty

The site and everything on it are provided "as is" and "as available", without warranty of any kind, express or implied — including any implied warranty of accuracy, merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that results are correct, that the site is available, or that it is free of errors.

No liability for decisions made from results

Calculator output is an estimate for planning. To the fullest extent permitted by law, we are not liable for any loss or damage arising from your use of this site or reliance on its results — including, without limitation:

• purchase, financing or sale decisions on equipment, vehicles or aircraft;
• tax positions, reimbursement elections or compensation negotiations;
• chemical dosing, equipment damage or water-quality outcomes;
• maintenance, operating or reserve budgeting for an aircraft.

See the calculator disclaimer for what these tools do and do not tell you. Some jurisdictions do not allow the exclusion of certain warranties or liabilities; where that is the case, the above applies to the extent permitted.

Acceptable use

You agree not to:

• scrape or bulk-download the site, or use automated tools that degrade it for others;
• republish the calculators or resell their output as your own service;
• attempt to disrupt, probe or gain unauthorized access to the site or its hosting.

Linking to any page here is welcome and needs no permission.

Intellectual property

The text, design and source code of this site are the author's work. The underlying physical, financial and chemical relationships the calculators implement are not claimed as anyone's property, and neither is publicly published reference data cited in the methodology. Quoting a short passage with a link back is fine; wholesale reproduction is not.

Third-party links and ads

Links to other sites, and any advertising shown here, are not endorsements. We do not control third-party content and are not responsible for it. See the advertising disclosure.

Governing law

These terms are governed by the laws of the State of Oklahoma, United States, without regard to its conflict-of-law rules.

Changes

These terms may change; the "last updated" date above will change with them. Continuing to use the site after a change means you accept the revised terms.
