Who can read it.

  • Private

    Open-weight models answer inside a trusted execution environment (TEE). Your browser verifies the enclave, then encrypts each message to it, so not even Thinkr can read the chat.

  • ZDR

    Claude, GPT, Gemini, and other models answer with zero data retention (ZDR). The provider reads the chat to answer it and promises by contract to keep nothing.

In ZDR and Open, Thinkr's proxy can read the chat in transit and writes none of it to disk.
