"Your iCloud storage is almost full." You've likely seen this email if you use the same Apple ID across devices. iCloud+ expands your cloud storage beyond the free 5GB and adds features like Private Relay, Hide My Email, and custom email domains. Plans start at $1/month for 50GB, $3 for 200GB, and $10 for 2TB, with higher tiers up to $60 for 12TB. All plans support family sharing and HomeKit Secure Video.

Apple One bundles iCloud+ with Apple TV+, Music, Arcade, Fitness+, and News+. The $20/month Individual tier includes 50GB iCloud+, while the $26 Family tier offers 200GB. The $38 Premier plan provides 2TB iCloud+ plus all services. Bundles can save money: Individual saves $12 versus separate subscriptions, Premier saves $32.

Choose standalone iCloud+ if you only need extra storage. Opt for Apple One if you already pay for Apple's other services. If you stop paying, iCloud stops syncing when you exceed your storage limit; Apple may delete backups after 180 days of inactivity. You can download files to devices or external drives before downgrading or canceling.
