Turn off iCloud completely
Depending on whether you want to stop using iCloud on all or only some devices, do one or more of the following:
On your iOS device’s Home screen, go to Settings > iCloud, then at the bottom of the screen, tap Delete Account.
Note:   If you delete your iCloud account, iCloud will no longer back up your iOS data. You can still back up your device in iTunes (for more information, open iTunes and choose iTunes > Help). 
On your Mac, open iCloud preferences, then click Sign Out.
If your Mac has OS X v10.7.5 and you turn off iCloud, your calendar information and reminders aren’t stored locally in iCal. If you want to retain your calendar and reminder information, you need to back it up before turning off iCloud. For more information, see the Apple Support article iCloud: Calendar & reminder data removed from Calendar and Reminders or iCal when disabling iCloud Calendar.
On your Windows computer, open the iCloud Control Panel, then click Sign Out.
Note:   If you turned on automatic download of music, app, or book purchases (in iTunes preferences or in Settings on your iOS device), your iTunes purchases are still downloaded to your devices.
