Nowhere by default. Your inputs live in your browser's memory while you're on the page; a copy of your recent calculations is saved to localStorage on your device so the History page works. Nothing is sent to a server unless you explicitly enable cloud sync.

The math is sourced from peer-reviewed and standard public formulas; you can read the formula in the result card. For decisions involving real money or health, always cross-verify with a qualified professional — calculators are educational, not advice.
