1. commitment to Privacy

At Cleset, protecting your privacy and securing your data is our utmost priority. We believe that your conversations should remain completely private, which is why we've implemented military-grade end-to-end encryption for all chat communications.

Zero Knowledge Promise

We've designed our system so that even we cannot read your messages. Your privacy is built into the very architecture of our platform.

2. How Encryption Works

Every message is protected by state-of-the-art encryption technology:

  • Local Encryption: Messages are encrypted on your device using advanced cryptographic algorithms before leaving your phone or computer.
  • Secure Transmission: Encrypted messages travel through our servers but remain unreadable to anyone except the recipient.
  • Recipient Decryption: Only the person you're messaging can decrypt and read your messages using their unique private key.
  • Perfect Forward Secrecy: Each conversation uses unique keys, so a compromise of one does not affect others.

3. What This Means for You

  • Complete Privacy: Cleset employees and systems cannot access your message contents.
  • Protection from Breaches: Even if our servers are compromised, your messages remain encrypted.
  • Local Control: Message decryption happens entirely on your device.

4. Your Security Role

Your security also depends on following these important practices:

  • Secure Your Account: Use a strong password and enable 2FA.
  • Protect Your Keys: Never share your encryption keys or credentials.
  • Keep Devices Secure: Use device locks and keep apps updated.

⚠️ Important: Chat History

Once you uninstall Cleset or switch devices, your old chats will be permanently lost. History does not automatically move with you because keys are stored on your device.

5. Key Management

  • Generated Locally: Unique keys are created on your device.
  • Stored Securely: Private keys never leave your device.
  • No Recovery: Lost encryption keys cannot be recovered by Cleset. This ensures maximum privacy.

6. Data We Collect (Metadata)

We collect only minimum metadata necessary for service operation:

  • Timestamps: When messages were sent/received.
  • User Identifiers: Sender and recipient IDs for routing.
  • Device Info: Basic device data for optimization.

What We CANNOT See: Message content, private keys, or decrypted data.
