I see that the app has been around for a while and heard good stuff, tried it and love it.

My problem is that if mod apps aren't open-source (Is it? I found the GitHub repo but not the source code) I'm very wary to use them, especially when the app uses the account token and has such access.

For the users who have experience with the app, is it open-source and do you trust it to not read your messages or do anything malicious?
