iCloud offers 5 GB of free storage for your iPhone or other iOS device. You have to pay if you want more storage than that. In order to conserve space in iCloud and have more room for what you want without having to pay extra storage space, there are customization options you can choose that are quick and easy.
To make sure that you are only saving the most important data, go to Settings and scroll down until you see iCloud. After you have tapped on the iCloud setting you can scroll down until you see Documents & Data and choose that option. From that point, you can see which apps are saving data in your iCloud account. You can off the feature if you don’t want to save anything, or tap off the apps that you don’t want to have saved to iCloud. This will help keep your storage down.
