I am surprised that, as I understand it, any app can potentially clone my Parse's Client KEY and App ID and act exactly as if it were my app, enabling and authenticating users on my app, having access to the same database and the same Cloud Code. So it is? Is there a way to avoid this?
EDIT:
My question is not related to privacy or data owned by the user. I read about the right way to use ACL, level permission of class, masterkey and so on.
But the question is how to prevent that another app cloning my KEY/ID can lean to the data of my app and do whatever we can make by my app, mixing its database with mine and also impacting on the request counter.
