In the Advanced section within Settings, you can view system health and remove your app:

Disabling Superwall

If you’d like to temporarily disable Superwall, click the Disable Superwall button. You can later resume it, but disabling Superwall stops all paywalls from being presented or placements being evaluated.

Removing your app

To permanently remove your app from Superwall, click the Delete Application button. You cannot undo this action.
