How do I share a public web application while keeping the web map and layers private

[BrennaContreras]

Hello,

Our organization is implementing a registration form using GeoForm. We want to be able to share the web application publicly, but want to keep the sensitive data being collected private. Is there a way for the public to access the web application (having the security as 'everyone (Public)') without having a log in, while also keeping all the data and web map security as private (within our organization). 

Any help would be greatly appreciated.

Can you use Feature Layer Views?

If you are to use Feature Layer Views, do you know what the procedure would be to update the feature layer view if the underlying data's schema changed?

On the visualization tab of the feature layer view you can pick the new fields added to be picked up by clicking on define fields to pick up new fields you added or hide existing. New fields are not visible by default and need to be checked on here.
