let me resume & please correct me if i'm wrong :
you don't take any % of our earning because you have your own deal with ad network company
you will only show your banner if other refuse to show (and this can be adjustable)
This is correct. So, let's say you use Enhance and select "Ad Network X". You will still have to create an account with X and you will have your own income dashboard with them. We don't take any of that money, nor do we even have access to that data to know what you're making.
But, we may have a deal with X where they track all apps going through Enhance and they pay us for those.
We will also add in another ad SDK that is our own, that is only called if X doesn't show an add when you call for an ad in your app.
If you picked multiple ad networks: X,Y,Z - then we wouldn't call ours until X, Y, and Z all passed. You can actually see our placement in your waterfall on the Enhance site.
Let me know if there are any other questions, more than happy to answer or clarify. :)
