No. All analysis happens in your browser using JavaScript. Your password never leaves your device.

A strong password uses 16+ characters, combines uppercase, lowercase, numbers, and symbols, avoids dictionary words, and does not follow keyboard patterns.

Entropy measures the randomness of a password in bits. Higher entropy means more possible combinations and harder to crack. 80+ bits is considered strong.
