ChatGPT saves data, including chat history, to train and improve its models. OpenAI has acknowledged that AI trainers may review conversations to enhance the system. Users are advised not to input sensitive or personal information. OpenAI introduced privacy controls in April 2023, allowing users to turn off chat history in the app's settings. Even with chat history off, data is retained for 30 days and may be monitored for abuse. Moreover, OpenAI plans to introduce a ChatGPT Business subscription with more control over data for professionals and enterprises.
