EncryptBoard is a privacy-first Android keyboard that encrypts your messages on-device before they leave your screen.

Every word you type stays yours. No servers. No logs. No tracking.

🔒 HOW IT WORKS
Type your message → tap Enter → it's instantly encrypted using AES-128 military-grade encryption and disguised as symbols or emojis. The recipient uses EncryptBoard to decrypt it back to plain text. Works in WhatsApp, Telegram, Instagram, Gmail — any app.

🛡️ FEATURES

• On-device AES-128-CBC encryption with HMAC-SHA256 integrity check
• Messages disguise as symbols ✦⊕☍, emojis 🌙🚀🔮, or natural-looking cover text
• Group passphrases — set a shared secret key with your contacts
• Floating ENC/DEC bubble — encrypt/decrypt without switching keyboards
• Quick Translator — paste cipher, decrypt, copy reply in one screen
• Glide typing support
• Word prediction
• AI assistant panel (ChatGPT)
• Zero internet required for encryption — fully offline
• No account, no sign-up, no data collection

🔐 ENCRYPTION DETAILS
• Algorithm: AES-128-CBC
• Integrity: HMAC-SHA256
• Key derivation: SHA-256 of your passphrase
• IV: Random per message (SecureRandom)
• All crypto runs locally on your device

💬 WORKS IN ANY APP
EncryptBoard is a full Android system keyboard. Switch to it once and use it everywhere — WhatsApp, Telegram, Signal, iMessage (via Android), Gmail, Instagram DMs, SMS, and more.

⚡ QUICK TOOLS
Not ready to switch keyboards yet? Use the Quick Translator screen to paste a cipher message, decrypt it, type your reply, encrypt it, and copy — all in one place without changing your keyboard.

👥 GROUP ENCRYPTION
Set a custom passphrase that you share with your group. Anyone with EncryptBoard and the same passphrase can read your encrypted messages. Change the passphrase anytime to create new private subgroups.

🔍 COVER PROFILES
Choose how your encrypted text looks:
• Symbols — futuristic glyphs ✦⟟☍∆
• Emojis — cosmic emoji sequences 🌙✨🚀
• Cricket scores, shopping lists, movie reviews, tech logs, and more — your encrypted message looks like normal text

📱 PERMISSIONS EXPLAINED
• Keyboard (InputMethodService) — required to function as a keyboard
• Display over other apps — optional, for the floating bubble
• Internet — only for the optional AI assistant panel
• Notifications — only while the floating bubble is active

No READ_CONTACTS. No location. No microphone. No camera.

EncryptBoard is open source. Your privacy is the product.
