Data privacy is the set of practices and guarantees around how personal or sensitive information is collected, stored, used, and protected from unauthorized access or misuse. For an AI product specifically, this covers what user inputs and conversation history are retained, for how long, who can access them, and whether they're used to further train the underlying model.
For ChatGPT specifically, users can disable chat history, in which case new conversations aren't used to train OpenAI's models and are generally retained for a limited window, typically 30 days, primarily to allow monitoring for abuse before being permanently deleted. Data privacy has become a central design concern across the AI industry more broadly, since training on user-submitted data raises real questions about consent, data minimization, and how long conversational data should reasonably persist.
