You can manage the notifications the Avanlee app sends your device depending on your subscription tier. At every level (Basic, Essential, and Premium) you can toggle notifications on or off, however, at Essential and Premium, you can choose which notifications you would like to turn on and turn off.
To access notification settings, click on the menu in the upper left hand corner and click on Your Notification Settings.
From here, you can toggle notification settings on or off, based off of your desired notifications.
