Entropy

Entropy is an open-source, fully offline password generator built for security-conscious users who want complete control over their credential strength.

Instead of arbitrary password ratings, Entropy calculates and displays the exact mathematical entropy (in bits) of your generated passwords based on character pool dynamics.

Key Features:

• Exact Entropy Calculation: See precise bit strength metrics updated in real-time.
• Fully Offline & Secure: No internet permission required. Your passwords never leave your device.
• Anti-Snoop Protection: Includes FLAG_SECURE window integration to block screenshots and hide app previews in the Android recents switcher.
• Customizable Character Sets: Toggle uppercase, lowercase, digits, special symbols, and exclude visually ambiguous characters (like 1, l, O, 0).
• Modern Material 3 UI: Clean, responsive layout with native Dark Mode support and Jetpack Compose architecture.
• Fast Copy: One-tap action to quickly copy generated credentials to your clipboard.

Entropy is built with zero telemetry, zero analytics, and zero external network calls.
