This is a very well done app. Only thing I am wondering is the privacy aspect of things and whether user information is collected during use. I checked network activity and it looks like it's phoning into openAI's API directly (I chose the API route instead of chatGPT mode) as well as "simplejsoncms.com".
Just did a network trace and it's nothing nefarious. The app just sends a POST request asking for the latest version of the app which is stored at this site. Literally the only response from the request is "{"latestVersion":72}". So no data is being sent anywhere other than OpenAI.
