You're right, the website should contain a more explicit note that user data is subject to OpenAI data retention policies. (However, I do mention that "Your data is never recorded, and opted out of future model training according with OpenAI API policies"). OpenAI did change their policies recently, and opted out any API data from future model training and promised us they delete it within 30 days. I wouldn't call it false advertising, but note taken, users must be explicitly told that their data is sent to OpenAI.
