Pushteavitusi

Pushteavitusi, commonly known as push notifications, are short messages delivered by apps or websites to a user’s device. They appear as banners, alerts, or badges and may include text, images, or quick actions. Pushteavitusi can be received even when the application is not actively in use, enabling timely updates or reminders.

Operation typically requires user consent. The app or site registers with a push service and receives a device-specific subscription token. The server then sends a payload to the push service, which delivers the message to the user’s device. On mobile platforms, native services such as Apple Push Notification Service (APNs) or Google’s Firebase Cloud Messaging (FCM) handle delivery. For the web, the Push API and a service worker manage push events and display notifications.

Platforms and standards vary by ecosystem. Native apps rely on APNs or FCM, while web implementations follow Web Push standards and the Notification API. These systems enforce policies to prevent abuse and control delivery timing.

Privacy and control are central considerations. Users must opt in and can adjust notification settings at the OS or app level. Platforms may collect preferences to tailor content. Developers should avoid sensitive data in payloads and respect opt-out choices to minimize disturbance.

Applications and impact: Pushteavitusi improve timely communication, engagement, and transactional updates. They also pose risks of notification fatigue and privacy concerns, requiring thoughtful design, clear opt-out options, and adherence to privacy regulations.
