How can I use ChatGPT for documents that should remain private.

This Reddit thread addresses privacy concerns when using ChatGPT with sensitive documents, noting that standard consumer plans (Free/Plus) may store conversations and use them for model training unless users take specific steps to opt out. Key options discussed include enabling Temporary Chat mode to prevent permanent history storage, turning off model training in Data Controls settings, and upgrading to Team or Enterprise plans, which exclude user data from training by default and offer stronger retention controls. For maximum privacy with highly sensitive documents, alternatives such as the OpenAI API with Zero Data Retention endpoints or purpose-built enterprise AI tools are generally recommended.

We are in dire need of privacy laws for AI .
