Is DeepSeek private on Thinkr?
In Private mode, yes. DeepSeek V4.1 Flash runs inside an enclave that your browser verifies, so neither Thinkr nor DeepSeek can read the chat.
Private mode runs the model on cloud GPUs in confidential computing mode, not on the servers of DeepSeek. Your browser verifies the remote attestation of the enclave, then encrypts each message to it.
The other DeepSeek models of the app, DeepSeek V4 Flash Vision Exp, DeepSeek V4 Pro, DeepSeek V4 Flash, DeepSeek V3.2, and DeepSeek V3.1, run with zero data retention: the provider reads the chat to answer it and keeps nothing.
