Your Privacy, Our Priority
Experience truly secure messaging with military-grade end-to-end encryption. Your encryption keys never touch the internet - making it mathematically impossible to decrypt your messages. Not even we can read them.
You Control Your Security Level
The strength of your password determines the level of protection for your messages. Test your password strength and see how long it would take to crack with a brute-force attack using our 🔐 Password Strength Calculator
End-to-End Encryption
Every message is encrypted directly on your device using AES-256 encryption. Only you and your recipient possess the keys to decrypt and read your conversations.
Client-Side Encryption
Encryption keys are generated and stored exclusively on your device. Share keys offline with trusted contacts for maximum security - no key ever touches our servers.
PBKDF2 Key Derivation
Your password goes through 100,000 rounds of cryptographic hashing before generating encryption keys. This process slows down brute-force attacks by 100,000x - turning a 6-day attack into 1,600+ years. Even weak passwords become exponentially harder to crack, giving you time to change them if compromised.
Zero Knowledge Architecture
We mathematically cannot read your messages. Our servers only store encrypted data - even system administrators and law enforcement cannot access your conversations.
Real-Time Messaging
Enjoy instant, lightning-fast communication without compromising security. Our optimized encryption ensures zero lag while maintaining maximum protection.
Cross-Platform Sync
Seamlessly access your encrypted conversations across web, mobile, and desktop. Your messages sync instantly while remaining completely secure.
How Our Encryption Works
Understanding the cutting-edge technology that keeps your messages private, secure, and completely unreadable to anyone except you.
Create Your Encryption Key
Choose a strong password that serves as your encryption key. Using symmetric cryptography (AES-256), the same password encrypts and decrypts messages on both ends - keeping your key completely offline.
Share Keys Through Secure Channels
Exchange your encryption password with trusted contacts through offline channels - in person, phone call, or encrypted messages. Never send encryption keys through unencrypted channels.
Unique Key Per Conversation
For maximum security, create a different encryption password for each conversation. This means even if one key is compromised, all other conversations remain secure.
Local Message Encryption
Your messages are encrypted locally on your device before being transmitted. The plaintext never leaves your device - only encrypted ciphertext travels through the network.
Secure Server Transit
Encrypted messages pass through our servers but remain completely unreadable. We use TLS/SSL for transport security, adding an extra layer of protection during transmission.
Optional Unencrypted Mode
Need to send a quick message without encryption? Toggle unencrypted mode for convenience. These messages still benefit from HTTPS/SSL transport security and server-side authentication.
