Thanks! I didn't see that. Relevant bit for convenience:
we call model providers on your behalf so your personal information (for example, IP address) is not exposed to them. In addition, we have agreements in place with all model providers that further limit how they can use data from these anonymous requests that includes not using Prompts and Outputs to develop or improve their models as well as deleting all information received within 30 days.
Pretty standard stuff for such services in my experience.
