I understand that only those who make 1 or more API call is counted as an active user but the line "Every App has an Active User" in the "Getting Started" guide is throwing me off. The way my app will work is it will be free and there will be an IAP to unlock the features that Kinvey enables (datastore, syncing, logging in, etc). So all users will have the Kinvey libraries packaged in their app but users who have not bought the IAP will not call any Kinvey code and will be storing their data with a traditional local sqlite db. I am assuming that means that only people who have paid for the IAP (and makes an API call) will be considered an Active User by Kinvey, correct?

Also, completely unrelated question. I haven't fully dived into all the documentation yet, but I assume that it is possible to invite other users to be able to read/write your collections right? Looks like this http://devcenter.kinvey.com/android/guides/security# is about that.

Thanks

Gary:  

It is possible to do this using either a system account or using some kind of anonymous account that everyone uses until they are authenticated.   Otherwise, you could just do a test for the IAP existing before you load any Kinvey code and it won't increase your users on it's own. 

And yes, that guide covers r/w permissions for collections / entities.

Thanks,
