Do you collect my data when I use a tool?
No. All calculations and data processing happen entirely in your browser. Nothing you type into any tool is ever sent to our servers. Read our Privacy Policy for full details.
Can I trust the calculation results?
Our calculators use well-established formulas and algorithms (such as the Mifflin-St Jeor equation for calories, the US Navy method for body fat, etc.). However, results are estimates for informational purposes. For medical, financial, or legal decisions, always consult a qualified professional.
