No. We do not sell your data or share your content with third parties for marketing purposes.
The above is from the Data Usage FAQ on their help page. I have opted out of them using my data for training using their opt-out form. However, I can’t find anything that states they won’t sell my content for other reasons. I am assuming that, while I opted out of improving the model, that they still retain my prompt/completion pairs, and reserve the right to sell this data for non-marketing purposes. Meaning… that in the future, OpenAI could sell my content to another company and it could end up being used in their models.
I think you’re good, at least on the “content” part
