Does Claude Pro train on my conversations?
No, not by default, and this is the part where we want to be honest about Anthropic. Default-no-training on consumer Claude Pro conversations is genuinely industry-leading, it is materially stronger than the default settings on the comparable consumer subscription from OpenAI, and the Anthropic Public Benefit Corporation charter makes the safety posture a fiduciary commitment rather than a marketing line. If the buyer's only privacy concern is "the AI lab quietly trains on my chats", Claude Pro closes that gap well and a different vendor is not required. We do not train on your messages either, and that is a policy too: our servers handle your conversations, only the model runs in an Intel TDX enclave.
