No, ChatGPT is not confidential for users. The system stores and analyze every interaction with the model. For that matter, users must collaborate with ChatGPT in a manner that does not violate the established guidelines. Guidelines cover the topics of the ethical usage of the model to avert potentially harmful content creation. In addition, the OpenAI team is also concerned with the privacy and security of the user's data and has already managed this issue by implementing data anonymization techniques that allow the team to secure user identities and sensitive information.
