## What is CryptoDuck?

CryptoDuck helps you and your friends create a secret language only insiders can read.

Type a message, pick an encryption rule, and get ciphertext in one tap. Share it anywhere - only those who know the rule can decode it. Perfect for couples, close friends, and fun group chats.

[Core Features]
- Encrypt and decrypt text with custom rules
- Build your own cipher: letters, numbers, emoji - mix freely
- Rule management: create, edit, import, export, and share via Deep Link
- Share as plain text, file, or beautiful ciphertext card (Pro: no watermark)
- History: auto-save sessions with one-tap refill (Pro)
- Rule Store: couple packs, emoji ciphers, gaming codes and more

[System Extensions]
- Home Screen Widget: see your active rule, jump straight to encrypt or decrypt
- Shortcuts: encrypt or decrypt without opening the app, results copied to clipboard (Pro)
- iCloud sync: keep rules across your devices (Pro)

[Privacy First]
- Plaintext, ciphertext, and rules stay on your device by default
- No ads, no third-party analytics, no cross-app tracking
- Optional iCloud sync is handled by Apple

[Free vs Pro]
Free: 3 manual rules, 12 total, 500 chars per encryption
Pro: unlimited rules, no char limit, history, iCloud sync, watermark-free cards, Widget, Shortcuts and all paid rule packs

[Important Notice]
CryptoDuck uses custom character mapping - not AES or military-grade cryptography. Do not use for highly sensitive data. Ideal for fun secret messaging between people who share a rule.

Download CryptoDuck and start your secret conversation.
