Are my passwords stored anywhere?

No. Passwords are generated in your browser using the Web Crypto API and are never transmitted or saved.

Do I need an account?

Are the calculator results professional advice?

No. Results are estimates for general information. BMI is a screening measure, and loan figures can differ from your lender's.
