Q: How do I turn off iCloud on my phone without deleting it altogether? Want to save space.

Hi KleeDanielle,

iCloud does not use the storage space on your iPhone.  You access the music, contacts, calendars, photos, etc. from the cloud using your device.

The resource below will explain how to see what data is being stored on your iPhone and how to free up space if you need it.
