I downloaded an app for my tv called "smart tv client for twitch" And I had to log in to watch the broadcasts, but I'm afraid of being hacked because I'm new to this world of Android TVs, does anyone use or have used this app? (Sorry for typos, I'm using the translator)

Also, you can try S0undTV if the aforementioned doesn't fit you. It's more minimal and straight to the point.
