iCloud Backups

iPhone secretly sends your call history to Apple even if iCloud Backups are turned off

However, a new report from a security firm suggests Apple's online syncing service iCloud secretly stores logs of its users' private information for as long as four months — even when iCloud backup is switched off.

Russian digital forensics firm Elcomsoft discovered that Apple's mobile devices automatically send its users' call history to the company's servers if iCloud is enabled, and stored that data for up to four months.
