Anyone actually preventing chatgpt from using my data successfully?

Probably a basic question, but how do you actually prevent chatgpt from using my data? Happy to be told i'm approaching this the wrong way. How do you do it?

In ChatGPT: Settings > Data Controls > turn off "Improve the model for everyone". That stops new chats being used for training. Temporary Chat also doesn't get used for training. Older chats you've already had, delete them if you're worried. If you're on a business/team plan, training on your data is off by default.
