Emoji Code

Secure your texts, share custom emoji keys, and chat with total privacy!

EmojiCode is a premium, offline-first encryption utility that transforms your private text messages into completely secure, customized emoji strings. Built on the principles of zero-trust architecture and total data sovereignty, EmojiCode ensures your private chats remain strictly private.

With advanced AES-256 encryption operating entirely on-device, you can bypass standard text sniffers, protect messages with passphrases, and share custom emoji keys with friends.

🌟 KEY FEATURES
🔒 Offline-First Cryptography: Every single encryption and decryption operation occurs locally on your device. Your raw texts, passwords, and decrypted keys never touch the network, keeping your data safe from interceptors.
⚡ Inline System Selection Menu (Android PROCESS_TEXT): Encrypt or decrypt texts directly inside other applications (like WhatsApp, Gmail, Telegram, or Messages) inline. Just highlight, tap "EmojiCode Encrypt" or "EmojiCode Decrypt", and watch it replace in place!
🎨 Built-In & Custom Emoji Packs: Map standard cryptographic text to 9 thematic built-in packs (Classic, Love, Animals, Gaming, Tech, Nature, space, Symbols, Flags) or create your own custom emoji pack matching your style.
📤 Share, Import & Export Maps: Easily export your custom emoji keys as shareable files or scan QR codes to instantly sync packs with friends for seamless mutual communication.
🔑 Optional Passphrase Security: Secure sensitive messages with password-based encryption. The app uses key stretching (5,000 rounds of SHA-256) to ensure maximum cryptographic strength.
👥 Account-Free Access (Guest Mode): Continue instantly without registering an account. Your settings, configurations, and history logs stay safely inside your device's native database.
🔄 Optional Google Preferences Sync: Log in securely with Google to backup your app preferences, theme choices, and custom emoji pack configurations via Google Firestore. Your messages and keys are always excluded from sync.
🛠️ HOW IT WORKS (ROUND-TRIP PRIVACY)
Encrypt: Type or select text, choose your emoji pack (and optional password), and generate a secure emoji string.
Send: Copy the emoji message and send it through any chat app (WhatsApp, email, SMS).
Decrypt: The recipient selects the emoji string, clicks Decrypt, enters the password (if set), and reads the original message instantly.
🛡️ PRIVACY COMMITMENT & TRANSPARENCY
Zero Messages Transmitted: We do not run cloud message servers. We cannot read, intercept, or restore your messages or passphrases.
Local Storage Protection: Local configs and history logs are stored inside the application sandbox, fully protected by your Android operating system.
Minimal Permissions: The Camera permission is requested solely for scanning QR codes, and Storage access is used only to save custom pack files.
