It's at the top of the Settings menu. If you don't want a particular app to sync its data to iCloud, you can scroll down and move an app's associated slider to the Off (gray) position. This displays a list of apps that can be backed up to iCloud. This will display a full list of local app data that has been stored to your iCloud backup. The amount of space used by the app data is listed under the app name. This data is what is used when restoring your device using an iCloud backup and will not affect the data currently stored on your device. This both deletes the backed-up data and prevents the app from backing up to iCloud in the future.
