Can I remove a client that an application is published to so they no longer have access to the applicaiton?

If i publish an application to a user (with out developer access) and later I need to remove this users access to the application is there a way to do this?  I cant see anything in my developer zone.  Im thinking I cant because the application is now on the other users zoho account and has data that likely we dont want to lose.

Is there a way to remove access ? 

If not does this mean in order to maintain full control of all databases, I need to own all zoho accounts that I share the application with and if i don't want someone to have access anymore. since im the administrator to the account, i just remove their access?

Also, can I stop a user that I have shared an application with from copying the application by going to Options -> Copy Application or duplicating it?



Thanks
