Deleting your account removes your synced configuration, any custom icons stored for you, and the account itself. It cannot be undone.
Open NetCage and go to Settings, then Account, then Delete account. This is the quickest route and it is the same operation this page performs.
Sign in with the same Google account, then confirm below. You will be signed out and the data listed above will be removed.
Your rules, profiles, schedules, preferences, hidden apps, custom icons, the record of your devices, and your account.
Anything held only on your phone. Uninstalling the app removes that. Deleting your account does not uninstall NetCage or release apps you have caged locally.
