Currently Qlik Sense Cloud is freely available. The subscriber can share their Qlik Sense apps with up to 5 users as you know. There are plans to allow more users, but not at this moment, so you cannot change this on the fly. At the moment - it seems whatever you put in the shared cloud on your account - is shared with others that you invite. There isn't individual user app / user share control....yet.
Let me know if you have any other questions.
If you have not seen this, please take a look at the introduction and How To video here:
