How to remove your data from ChatGPT and OpenAI
Two separate things matter here: stopping your chats being used for training, and removing personal information the model may surface about you.
Stop your chats training the model
- Open ChatGPT → Settings → Data controls.
- Turn off “Improve the model for everyone.”
- Chats stay in your history but are no longer used for training.
Delete your account and data
- Settings → Data controls → Delete account. This is permanent.
- Export your data first from the same screen if you want a copy.
Remove personal information about you
OpenAI runs a personal-data removal request process for people whose information appears in model outputs. Submit it with specific examples of the output concerned.
Reality check: opting out prevents future training. Data already absorbed into a trained model cannot currently be extracted — “machine unlearning” is an unsolved problem.
