Forum Thread: IOS Monitoring via iCloud; Can We Decode the Data Ourselves?

So, its no secret you can monitor an IOS device if you have the users AppleID credentials via a 3rd party application like mSpy etc. My question is, can we obtain this information ourselves without including a 3rd party? Is there software readily available to retrieve and decode the icloud information into a practical GUI ? or even a basic Linux app which can pull that icloud information down into a xml, or something i could manually code to make sense of that data?

Thanks.
