Someone would probably pull your oauth and abuse it if you include it in your app, so don’t.
If the purpose is to only fetch data, you can use justinfan to log in anonymously, just use NICK justinfan1234 to log in, you don’t have to send PASS, it will log you in anyway. (you can replace 1234 with random numbers)
This login allows you to listen to messages in the joined channels, but not send any commands/messages whatsoever (except JOIN and PART as far as I’m aware).
