Do Twitch terms of use apply in App?

Hello,
I was wondering if an application that uses the Twitch connection and retrieves information from its API should obey certain rules regarding its content.
Thank you.

Any app/tool utilising the API or other third party product is covered by the Twitch TOS and additionally the Twitch Developer Services Agreement
