Yes, ChatGPT does store user data. OpenAI explicitly states that conversations are typically stored and may be reviewed by human trainers to improve the models. This includes your inputs and the AI's responses. However, users have the option to turn off chat history in their settings, which prevents new conversations from being used to train their models and removes them from the sidebar. Even with chat history off, conversations are retained for 30 days for abuse monitoring before being permanently deleted. OpenAI emphasizes its commitment to data privacy, taking steps to de-identify data during the training process. More details: https://info-list.top
