Terms of Use

By using Calculator ToolBox(the "site") you agree to these terms. If you do not agree, please do not use the site. The site is free to use and requires no account.

The site is a collection of browser-based calculators (health and finance), utility tools (hardware testers, a clock, an IP lookup, a whiteboard), and board games. All features run in your browser and are provided free of charge, supported by advertising.

Everything on this site is for education and entertainment only. The health calculators (BMI, BMR, body fat) use standard population formulas and are not a medical assessment, diagnosis, or treatment advice — consult a healthcare professional for decisions about your health. The interest and loan calculators are simplified models and are not financial, investment, tax, or legal advice — verify any real decision with a qualified professional and your actual contract terms. Hardware tester results are indicative, not a certified diagnostic.

Use the site lawfully and normally. Do not attempt to disrupt it, probe or overload the infrastructure it runs on, scrape it for republication, or misuse the online game connections to harass others or transmit unlawful content. Online chess play connects you directly with another player's browser; you are responsible for what you send.

The site's design, text, and code are the property of the site operator. The board games implemented here (chess and its variants, Go, and others) are traditional games whose rules are public domain. Map data on the IP tool is © OpenStreetMap contributors. You may link to any page freely.

Some features rely on third-party services (hosting, advertising, geolocation, map tiles), described in the Privacy Policy. Those services belong to their operators and may be unavailable or change without notice.

The site is provided "as is" and "as available", without warranties of any kind, express or implied — including accuracy, fitness for a particular purpose, and uninterrupted availability. Calculations may contain errors; formulas are simplifications of reality.

To the maximum extent permitted by law, the site operator is not liable for any damages arising from your use of, or inability to use, the site — including decisions made in reliance on calculator results. Your only remedy for dissatisfaction with the site is to stop using it.

Features may be added, changed, or removed at any time. These terms may be updated; the date above reflects the latest revision, and continued use after a change means you accept the revised terms.
