Looking for Chat GPT-4 advice

Hi. I’ve been looking at various Chat GPT 4 apps. A friend recommended me AI Chatbot (iPhone app). However, when I looked it up, it had a pretty lousy privacy policy. Can anyone recommend a decent, privacy oriented Chat GPT4 app?

FYI, it doesn’t have to be a free one.

Thanks!
