Confidential Computing

DeepSeek inside an encrypted enclave

Same model, same capability. But with architectural privacy you can verify — not a promise in the terms of service.

End-to-end encryption

Your prompts are encrypted in your browser before they leave your device. They're only decrypted inside the hardware-secured enclave. No middleman can read them.

Confidential computing

DeepSeek V4 Pro runs inside a Trusted Execution Environment (TEE). Not even ChatLock's infrastructure can observe your data during inference.

Zero data retention

Once your response is delivered, the enclave's memory is wiped. No logs, no copies, no training data. Ever.

Verifiable privacy

Cryptographic attestation lets you independently verify the enclave is genuine and runs the expected code. Don't trust — verify.

What changes with ChatLock

Same open-weight model. Real difference in how your data is handled.

Your prompts are encrypted end-to-end from browser to secure enclave
Processing happens inside confidential hardware, not even the operator can observe it
Zero data retention: nothing is saved, nothing trains future models
Cryptographic attestation so you verify yourself rather than trusting a policy
