Terms and conditions
By using AskCalculators, you agree to these terms.
Use of the site
You may use the public calculators and machine-readable files for lawful personal or business purposes. Do not misuse the site, interfere with access, or present a result as guaranteed when it is not.
Calculations and estimates
Results are produced from the values, formulas, assumptions, and rules shown on each page. Results can be incomplete, outdated, rounded, or wrong. You are responsible for checking inputs and deciding whether a result is suitable for your use.
No professional advice
AskCalculators does not provide financial, tax, legal, medical, engineering, safety, or other professional advice. Important decisions should be checked with a qualified professional and current primary sources.
Local files and historical results
Your browser can evict local data. Export backups of important projects. Imported and historical results are records, not authenticated answers; recompute current inputs before relying on them. Deleting site data does not erase downloaded files or links already shared.
Construction Planning Pack
The downloadable pack adds reusable estimating files and branded layouts. Core public calculations, ordinary exports and access to your existing data remain free. Where checkout is enabled, payment takes place on Stripe. The product purchase terms state the seller, price, delivery, support, license and refund arrangements before purchase. A static return page does not confirm payment or grant access to a download.
Saved URLs
Calculator links can carry inputs in their query string or fragment. Neither format is encrypted or access controlled. Do not place confidential, personal, financial-account, medical, or other sensitive information in a calculator URL.
Availability
The site may change, remove, or correct calculators without notice. Access may be interrupted. No promise is made that every calculator, link, file, or result will always be available.
Ownership
The site design, original text, code, and organization may be protected by intellectual-property laws. Third-party names, references, libraries, and source materials remain the property of their owners.
Third-party links
Links to outside sources are provided for reference. AskCalculators does not control their content, availability, security, or privacy practices.
Limits
To the fullest extent allowed by applicable law, AskCalculators is provided without warranties. The site owner is not responsible for losses caused by reliance on a calculation, unavailable service, incorrect input, or use of a shared URL.
Changes
These terms may be updated. The effective date on this page will change when a new version is published.
These general terms do not replace the product-specific purchase terms or any mandatory rights under applicable law. The operator must review the terms for the actual business before activating checkout.
