ChatGPT doesn’t process personal data unless explicitly provided by the user. It is designed to respect user privacy and confidentiality. OpenAI has implemented strict technical measures to prevent the model from storing personal conversations or using them to improve the model. As a language model, it generates responses based on patterns and knowledge learned during its training, and does not learn new information from individual users. However, OpenAI retains personal data provided via the chat interface as per their data usage policy. It is advised not to share sensitive personal information with ChatGPT.
