You can get notifications of available jobs via SMS or email. By default this is on, but you can change it anytime by going to "More" -> "Advanced Settings" -> and "Notification Settings" (or search for "Notifications").
Note, these are limiting what types of jobs you will be get notified for not when you will be notified.
If you want to limit what time you receive notifications, you can do so in your "Do Not Disturb" settings on your phone. These allow you to silence SMS and in-app notifications for TIDY.
