Does this calculator work offline?

Yes. After the first load it runs entirely in your browser.

Are my calculations tracked?

No. Tools Pack is privacy-first and does not send your input anywhere.

A number followed by % is treated as a percent. For example 12% becomes (12/100). So 12% * 200 = 24.

Like most calculators in the browser, this uses floating-point math which can show tiny rounding artifacts for some decimals.

Basic arithmetic with parentheses: + − × ÷ (also * and /), decimals, and % as described above.
