Your chats with GPTs are not shared with builders.

If a GPT uses third party APIs, you choose whether data can be sent to that API.

When builders customize their own GPT with actions or knowledge, the builder can choose if user chats with that GPT can be used to improve and train our models.

These choices build upon the existing privacy controls users have, including the option to opt your entire account out of model training.

How do I turn off chat history and model training?

Web interface:

To disable chat history and model training, navigate to ChatGPT > Data Controls. While history is disabled, new conversations won’t be used to train and improve our models, and won’t appear in the history sidebar. To monitor for abuse, we will retain all conversations for 30 days before permanently deleting.



Please note, this will not prevent unauthorized browser add-ons or malware on your computer from storing your history.

Does this functionality sync between web and mobile devices?

This setting does not sync across browsers or devices. You will have to disable chat & history on each device/browser.

What if I want to keep my history on but disable model training?

We are working on a new offering called ChatGPT Business that will opt end-users out of model training by default. In the meantime, you can opt out from our use of your data to improve our services by filling out this form. Once you submit the form, new conversations will not be used to train our models.

As with the rest of the platform, data and files passed to the OpenAI API are never used to train our models and developers can delete the data when they see fit.
