Legalities of using graphics and titles?

I want to make an app, right now just for myself, but If i were to make it publically available (google play store) what would I need to declare, and what am I allowed to use? What about profitable ads on the app?

Thanks!

microsoft content usage rules

I believe you’re allowed to make the app public but

  • you’re not allowed to make any profit so no ads, and it has to be free - you need to make it clear it’s not offical - you need a link to the content usage rules, probably just throw it in the description of the app on what ever store you put it onby the way, what kind of app is it?
