Privacy Policy

CalculatorShelf does not need an account to use calculators. Shared result URLs may contain the inputs you put in the query string, so do not share sensitive information in calculator parameters.

How CalculatorShelf keeps pages useful

• Every finished calculator needs a working tool and a clear worked example.
• Pages need page-specific formulas, examples, mistakes, FAQs, and disclaimers.
• Safety-sensitive tools provide planning estimates only; compare results with current product labels, official guidance, or a qualified professional.
• No runtime AI is used to calculate results.

Google Analytics

CalculatorShelf uses Google Analytics to understand aggregate page usage, calculator interactions, and technical performance. Google Analytics may use cookies or similar identifiers. You can learn how Google uses data from sites that use its services at Google's partner-sites policy.
