Security Overview

πŸ” Messages are encrypted using a PIN-derived session key unique to each chat.

🚫 No messages ever leave your local network β€” LanChGo works fully offline.
πŸ›‘οΈ Your data stays private. Nothing is stored on external servers.
🧠 Encryption Strength LanChGo uses AES-256-GCM encryption with PBKDF2-HMAC-SHA256 key derivation for every session β€” secure, private, and fully offline.
