@Charles ☭ H @modulux Frankly push notifications at least on #
IOS and #
Android are here for years. Apps such as messengers, social networking apps, traditionally banking apps, insurance companies, postal and transport services, delivery services, taxis, schools, shops and outlets, even some news apps have always used push notifications. Mobile operating systems are activelly dissalowing these apps to run on the background for extended period of time in order to prolong the device's battery life. Then the app vendors can leverage the platform's push notification systems to literally woke their apps from so called deep sleep in order to fetch the latest updates and generate a notification. And they are really doing it. It's a typical scenario. Monitoring ones push notifications state agencies can gather plenty of data about an individual such as what apps and services they are using, they daily routines, depending on the apps their social circles and similar.
