New information from an inquiry by the U.S. Congress shows smartphone companies are sharing data from push notifications as part of government surveillance.

Building out another piece in its business engine comes PlayHaven's Push. As the name suggests, it's a push notification system for iOS and Android, that's integrated into the company's other tools.

For iPhones, this service is provided by Apple’s Push Notification Service; for Android phones, it’s Google’s Firebase Cloud Messaging.

Responding to a senator's letter to the Department of Justice, Apple and Google have confirmed governments ask them for push notification data.

HNL Alert allows residents and visitors to sign up for updates on severe weather, emergencies and other important news via text, push notification, or email.
