OpenAI collects account data, all prompts and responses, file uploads, voice inputs, and a separate Memory that persists even when you delete chats. Training on your conversations is on by default; you must opt out. A federal court order (May 2025) requires OpenAI to preserve and segregate ChatGPT conversation data — including deleted conversations. API and Enterprise: training is off; your data is never used for training. OpenAI states they don't sell personal data or use it for targeted advertising.
