Does system data storage require iCloud or a computer?

iCloud or a computer is not always required, but account-based features and deeper troubleshooting often need a trusted account or computer.

Official support is the safer path when account ownership, payment data, managed-device policy, repair status, or possible hardware damage is involved.
