There are several reasons why you may want to turn off notifications in the Karma app. Perhaps it's a specific location you do not want to receive notifications from anymore, or you're on vacation and do not want any notifications at all from the Karma app. In order to stop receiving notifications from a specific location, go to the location within the app and then click the heart icon to stop following it. If you want to turn off notifications for the entire Karma app, go to Notification preferences in the app settings. You can always turn on the notes again at any time!
PS. In the Notification preferences there's an option to get silent notifications!
