> No. Strictly speaking, iCloud doesn’t even do backups; it syncs data

There’s literally a switch called “iCloud Backup” in Settings though. This isn’t a per-app data sync, it’s the full device restore that you can use if your phone gets stolen, dropped in the ocean, etc.

Although you should consider not using it for privacy reasons and running backups to a local machine instead, since last we heard Apple has the encryption keys and will happily hand the entire contents your phone to law enforcement given a warrant.
