Releasing a game

Hi everyone,

My name is Yogev, I’m about to release my first UE4 game and I need your help :o

I’ve read this, and saw I need to give a credit to Epic Games.
Is anywhere inside my game credit page (in-game credit menu) enough, or should this be at a different location then actually inside the game? (store page for example)

When I’m writing my EULA and Privacy Policy, should I mention the UE4 licenses?
My game isn’t connected to any server or collecting any data other then saving settings and user name at the user PC and replicating it through the network (online turn base game), should that be mentioned?
Is the engine\game collecting any data of the users I should be aware of and put it in my licenses?

What is the standard operation here?

Thank you very much in advance,
