EmojiCode: Offline-First Private Text-to-Emoji Encrypted Messenger

EmojiCode is a premium, offline-first privacy application that converts plain text messages into encrypted emoji patterns. Designed for high-integrity security, it allows users to secure their chats, send hidden messages, and share custom emoji keys without exposing any private data to the cloud.

All encryption and decryption happen strictly locally on the user's device. Using industrial-grade AES-256-CBC, PBKDF2-HMAC-SHA256 key stretching, and custom-mapped Base64-to-emoji packets, EmojiCode guarantees that no raw message text or cryptographic keys are ever transmitted over the network or saved in external servers.

• 01. Offline AES-256-CBC Cryptography: Local message security utilizing stretched key generation (5,000 rounds of SHA-256) combined with random salts and initialization vectors.
• 02. Dynamic System Menu Integration (Android PROCESS_TEXT): Seamlessly encrypt and decrypt selected text in any other application (such as WhatsApp, Gmail, Chrome, or Messages) directly inline without leaving the active app.
• 03. Custom Emoji Packs & Maps: Map cryptographic Base64 character sets to 9 built-in emoji packs (Classic, Love, Animals, Gaming, Nature, space, etc.) or design, import, and export unlimited custom packs to share with friends.
• 04. Secure Preferences Cloud Sync: Optionally authenticate with Google to securely synchronize custom pack configurations and app-wide preferences via encrypted Firestore records, completely isolated from message databases.
• 05. Zero Trust & Total Local Anonymity: Guaranteed offline-first architecture with zero account creation required, keeping logs, settings, and conversion history locally stored in native Hive DB tables.
