How do I uninstall the app?
You can uninstall Articles + like any other app on your iPhone, iPad or Mac.
On your iPhone or iPad, touch and hold an app from the home screen until all apps start to jiggle. Tap the remove icon in the upper-left corner of the app and confirm deletion.
If you have enabled the Cloud Library, data will still be stored in your personal iCloud account. In case you want to completely remove everything, you will need to manually delete it from the device settings.
Please note that this action can not be undone and will delete your articles from all synced devices:
Device Settings > Apple ID > iCloud > Manage Storage > Articles: Delete Data
On your Mac, move the Articles.app from the Applications folder to the trash. Local data will still be stored in the app's container.
Open Finder or the Terminal to manually delete it:
