Terms of use

The service

FreeOnline-Calculator.online provides free online calculators, unit converters, and educational content. The tools are provided as-is, free of charge, without accounts or registration.

Estimates, not advice

Results are estimates for information and education only. They are not financial, medical, legal, tax, or professional advice, and they don't account for your personal circumstances.

Before making decisions about loans, health, taxes, or contracts, verify figures with the relevant professional or institution. The formulas and assumptions behind each result are shown on its page so you know exactly what an estimate covers.

Acceptable use

You agree not to:

• Attempt to disrupt, overload, or probe the site or its infrastructure.
• Scrape the site in bulk or misrepresent its content as your own.
• Use the contact form for spam or unlawful content.

Intellectual property

The site's text, design, and code are our property. Mathematical formulas themselves belong to everyone — you're welcome to use them, and our explanations cite the standards they come from.

Liability

We work hard to be accurate, but we can't guarantee the site is error-free or always available. To the maximum extent permitted by law, we're not liable for decisions made based on results from this site.

Changes

We may update these terms as the site evolves; the date above reflects the latest version. Continued use of the site means you accept the current terms.
