Input data privately into my app

I am trying to input large amounts of data that would also display real time, so i would most likely need to keep within one app. My problem is im not sure how to input latge amounts of structure data while keeping the inputs hidden from regular users. I dont have any accounts so no way to log in. Im not sure how to go about this. Think of like a Espn with no accounts. How?

Consider looking at the following combination of features

Set an attribute on the user table saying if you’re an administrator or not.

Set up security on your pages so that when they load, they check if you’re an admin

Use conditional formats, turning visibility on and off if you’re an admin.

You’re going to have all that available to you, have a good play around.
