Final answer:
iOS app data is generally deleted along with the app unless backed up. Uninstalling an app without a backup will result in data loss.
Step-by-step explanation:
When an iOS app is deleted from a device, its data is typically deleted as well. This means that unless the app's data is backed up separately (e.g., via iCloud), the information stored within the app will be lost upon deletion. Apps do not automatically archive or transfer data to Apple when they are uninstalled. It is important for users to be aware that uninstalling an app will result in the loss of its stored data unless measures are taken to back up or preserve it.
