Terms of Service

By using quickcalc.ai ("the site"), you agree to these terms. If you don't agree with them, please don't use the site.

What this site is

QuickCalc.ai provides free, browser-based calculators for home improvement, health and fitness, dates and time, everyday math, personal finance, and gaming. There are no accounts, no subscriptions, and no fees to use any calculator on the site.

Estimates only — not professional advice

Every result produced by a calculator on this site is an estimate based on the inputs you provide and standard formulas, and is offered for general, informational purposes only. Nothing on this site constitutes medical, financial, legal, engineering, or construction advice. Calculators covering health (BMI, body fat, calorie needs, pregnancy due dates), finance (mortgage, loan, and paycheck estimates), and construction materials should not be relied on as a substitute for consulting a doctor, licensed financial advisor, contractor, or other qualified professional.

No warranty

The site and its calculators are provided "as is" and "as available," without warranties of any kind, express or implied, including but not limited to accuracy, reliability, or fitness for a particular purpose. While we make a genuine effort to keep every formula correct and up to date, we don't guarantee that any result is error-free.

Limitation of liability

To the fullest extent permitted by law, QuickCalc.ai and its operator are not liable for any direct, indirect, incidental, or consequential damages arising from your use of, or inability to use, this site or reliance on any calculated result — including financial loss, property damage, or personal injury.

Advertising

This site is supported by display advertising served through Google AdSense. Ads are provided by third parties, and we don't control or endorse the content of any specific ad shown. See the Privacy Policy for details on advertising cookies and how to control them.

Acceptable use

You agree not to misuse the site — including attempting to disrupt its operation, scraping it at a volume that degrades service for others, or using it for any unlawful purpose. The embeddable calculator widgets are provided for reuse on other sites via the embed code shown on each calculator page, provided the attribution link back to QuickCalc.ai is kept intact.

Intellectual property

The site's design, text, and code are the property of QuickCalc.ai's operator unless otherwise noted. You're welcome to link to any page on this site freely.

Changes to these terms

These terms may be updated from time to time; the "Last updated" date above reflects the most recent revision. Continuing to use the site after a change means you accept the updated terms.
