Are playerprefs saved to iCloud?


I developed a game using Unity3D, and used the playerprefs to save the game progress.
One of my users asked if the progress will be saved if he switches to a new iPhone.

I did not add any further functionality to my games. How does iOS handle the playprefs (if at all)? Are the stored in iCloud? If he restores his phone on a new phone will the game progress be saved?

Thanks in advance!

Doesn’t look like it since there’s Plugins Out there to do this:

iCloud PlayerPrefs AutoSync
iCloud for Unity
