Push notifications
Push notifications are alerts that an application or website can send to a device through its platform's mechanisms. They can communicate events, changes or messages
What it means, how it is used and where it comes up, with its related concepts.
What it is and how it works
Their operation depends on settings, permissions and connectivity. Technical permission does not necessarily express acceptance of every commercial message. The experience should explain which alerts will be received and allow preferences to be adjusted. For critical matters, sending should not be assumed to mean receipt or reading.
