How do I stop ChatGPT from using my chats to train its model?
Open ChatGPT Settings, then Data Controls, and turn off the switch labelled "Improve the model for everyone." This stops your new chats from being used for training. It does not delete your existing history, and the setting applies per account, so change it on every account you use.
How to do it
- Open ChatGPT SettingsIn ChatGPT, go to Settings to reach your account options.
- Go to Data ControlsInside Settings, open the Data Controls section.
- Turn off "Improve the model for everyone"Find the switch labelled Improve the model for everyone and turn it off. That's the whole change.
- Repeat on every accountThe setting is per account, so check and turn it off on each ChatGPT account you use before your next prompt.
Questions that come up
Will turning this off delete my existing chat history?
No. Turning off the switch stops new chats from being used for training, but it leaves your existing history in place. It only affects what happens going forward, not conversations you have already had, which remain accessible as usual.
Does one toggle cover all my ChatGPT accounts?
No. The setting applies per account, so turning it off on one account does not change the others. If you use more than one ChatGPT account, open Data Controls and turn off the switch separately on each one before your next prompt.
Does this stop my chats from being saved at all?
No. The switch only controls whether your new chats are used to train the model. Your conversations are still stored in your history so you can revisit them; the toggle changes the training use, not whether chats are kept.
