How to setup AdMob for an unreleased app on the Admob web-page ?

Recently I added AdMob to my project by using the EasyAdsPro plugin and it worked more or less smoothly. Currently it still is configured for using test ads. The app itself is not on any store and not released yet.

Can anyone help me and let me know how to configure this on the Admob website? I managed to set up my app there and to get an ID for it, but that’s it. Do I need an additional privacy policy document because of the advertising? What else needs to be taken into account, are there any good tutorials on this?
