whats the use of adding storage icloud if everytime you delete something from you phone it will also be deleted on icloud?

Hi geybigeyb,

Thanks for using Apple Support Communities. Based on what you stated, it sounds like you want to know what you can use iCloud storage for. I would recommend that you read this article, it may be able to help the issue.

iCloud: iCloud storage and backup overview

Your iCloud storage is used for iCloud Backup, iCloud Drive, iCloud Photo Library beta, app data and documents stored in iCloud, and iCloud Mail (your @icloud.com email account).

Cheers,

Mario
