Question about publishing applications for clients

Question about publishing applications for clients

When I publish an application to a client from the Developer Zone, and the client receives the application in their Zoho account, it appears that the client forever owns the application.  For instance, if I "remove" the application from publishing, the client continues to have full use of it.  If that is true, then the idea of having a subscription business model in which a client subscribes to the application (pays a subscription fee per month) wouldn't work, because if they don't pay the subscription they still have the application.

If that is all correctly understood by me, then my question is:  Is there any way to control access to a published application once it has been made available to a client?   If there isn't, then could Zoho dev team perhaps make such a control function available so the subscription model can work?

Thank you,
