Every calculator uses industry-standard formulas. Financial tools follow actuarial math; health tools use validated formulas like Mifflin-St Jeor and the US Navy method.
Calculators run entirely in your browser, so the numbers you enter are never sent to our servers. The Password Generator uses your browser's built-in cryptographic API. AI and some file tools do need to process your text or file on a server — our Privacy Policy explains exactly how.
