About this app

PIN Forge is a premium, lightweight, and fully offline Flutter application designed to generate cryptographically secure numeric PINs instantly. With an elegant, modern UI featuring neon-accents and glassmorphic designs, PIN Forge focuses on delivering secure random values without compromise.

Whether you need a 4-digit PIN for a card, a 6-digit passcode for a device, or a passcode for lock setups, PIN Forge creates them in milliseconds with complete user privacy.

## 🌟 Key Features:

🔒 Cryptographically Secure Random Generation
- Uses `Random.secure()` as the core random engine (with standard fallback) to maximize randomness.
- Each generated PIN is independent and mathematically unpredictable.
- Preserves leading zeros (e.g., `0042`, `000981`) to maintain standard length constraints.

🔢 Custom PIN Length Selection
- Instantly switch between 4-digit and 6-digit modes.
- Save selected preference locally using SharedPreferences.

🎨 Modern Neon Accent & Glassmorphic UI
- Elegant light gradient backdrop with modern Outfit and Space Grotesk typography.
- Soft-elevation cards, neon-border glows, and ripple feedback effects.
- Staggered digit scale-in counter animations that pop values onto the screen.

📋 Session-Only History Logs
- Keeps track of the last 10 generated PINs in the current session.
- Session logs are stored strictly in RAM and are permanently cleared when the app is closed.
- Quick "Clear History" button to empty the session log instantly.

📋 Clipboard & Haptic Feedback Integration
- Fast one-tap copy button next to the generated PIN.
- Light haptic vibration feedback on tap actions (Generate, Copy, Menu options).
- Floating success Snackbar notification when copied.

🛡️ 100% Privacy Focused
- Zero Permissions: No internet, no contacts, no camera, no location, no storage access.
- Zero Ads: Distraction-free, clean utility workspace.
- Zero Tracking: No analytical software, no tracking scripts, no third-party SDKs.
- Local Only: Everything operates strictly on your physical CPU.
