A push notification is a message sent by a website or mobile application that appears on your device’s screen, even if you’re not currently using the app or site. These notifications are designed to quickly deliver important updates, reminders, or alerts, helping users stay informed in real time. They can include text, images, or links and are commonly used for news updates, promotional offers, or security alerts. While push notifications can enhance user engagement and communication, users should manage their notification settings to avoid unwanted interruptions and protect their privacy.
