This wikiHow teaches you how to sign out of your LINE account and app on an iPhone or iPad. Although there is no sign-out option in the LINE app, iOS 11 and later users can log out of their account by closing the app loading in the device's storage space ("Storage") settings.
Step
Step 1. Open the iPhone or iPad settings menu (“Settings”)
The settings menu is usually displayed on the device's home screen.

Step 3. Swipe the screen and touch iPhone Storage or iPad Storage.
It's in the middle of the menu. A list of applications installed on the device will be displayed.
