Signing up for an iOS app that provides a paid service?

Question

Apple Developer Program

There is a service that provides for realtors to create 3D tours of apartments. There is an iOS app that realtors use to create these tours. When we uploaded this application to the store, apples forbade us to insert links to the site on the "About" page, since the site has registration and the service is paid and the money does not go to Apple) We removed these links and the application was successfully released, but only with authorization existing users. Now the customer wants to add registration inside the application, but is afraid that apples will just wrap it up and asks to study this issue. After reading the guides, I did not find anything suspicious and I see no reason not to let us into the store with registration. Please share your experience, who had such situations? Maybe someone knows for sure that they will not be allowed into the store? I will be glad to any cases, stories! Thank you.

Answer 1

If registration is in the application, then everything will be ok. You can even sell services and you can add a link to the site with payment if you make the same prices for purchases in the application and on the site.
