Every message is encrypted on your device before it reaches our servers. Private keys stay with you, and the server stores encrypted blobs only.
End-to-End Encrypted
Only chat participants can read messages
Client-Side Key Storage
Private keys never leave your device
Secure Key Rotation
Versioned keys help protect past chats
You create an account → Your device generates RSA keys
You send a message → It is encrypted with AES-256-GCM before upload
We store only encrypted data → Server cannot read plain text
Recipient decrypts → Only their device can unlock the message

Educational approximation only. Real-world security also depends on device safety, implementation quality, and key management.
| Data | Can We See It? | Why |
|---|---|---|
| Messages | No | Encrypted on your device |
| Chat content | No | Protected by end-to-end encryption |
| Passwords | No | Stored as secure hashes |
| Roll Number | Yes | Needed for login and account recovery |
| Account ID | Yes | Required for system operations |
We support versioned key rotation for chats. If a key is ever compromised, rotation helps ensure older conversations remain protected.
