Total Newbie Here

Got a great idea for an app and I have a couple of questions.

How do I charge people to have access to my info/content?

Also how do I charge people to have their info/content accessible via my app? (would I create virtual chains for them?)

And is it possible to charge a % to the second group of people when they charge people to have access to their info/content via my (original) app?

Any constructive guidance will be massively appreciated.

Thank you
