iPhone. The data that keeps the Apple from the phone calls we make from our iPhone via Facetime, but also from third-party applications, such as Viber, Skype and Whats App. The data remains in iCloud of the user, while there is the possibility to disable the feature.
From our calls, Apple collects data such as the phone number we call, date of call and duration of. The above data remains in iCloud for four months, and from these are excluded the written texts.
Apple argues that the specific data in the iCloud allow us to make calls from all of our devices and that it is very well protected. In a few words, if you make a Facetime call on iPhone, we can find the call on the iPad.
Of course, the company doesn’t want users to worry about the security of their data, as these are encoded in the iCloud. If you do not wish to send the data of your call, you have to stop the synchronization of iCloud data from your iPhone.
