Do iCloud enabled iOS apps require consent from the user? I'm developing an Android app that needs to store the user preferences somewhere in the cloud. If I enable the Google Drive's AppFolder in order to store the user's data, the user needs to give consent by authorizing access to their Google Drive account. I currently don't have my iOS device at hand and can't recall whether I needed to do the same thing when working with iCloud.
No, specific consent for your app is not required before the use of iCloud for documents and data. However, consent can be later be removed from your app in Settings.
