Once an Alarm has been set, only the person who the Alarm is for may change or delete it (coaches and team admins cannot change or delete Alarms for their players, only create them). Alarms can only be deleted by the target user by logging into their web account at app.swishhoop.com, tap Alerts along the top menu, find the Alarm they want to change and tap EDIT, then delete or change the Alarm.
