Diosapp apps store progress locally on your device, so it can only be lost if the app is deleted or its data is cleared.

App data is subject to the normal iOS device backup settings you control. If you enable iCloud or computer backup for the device, app data is included in that backup. We don't provide our own cloud sync.
