We are living through some pretty tricky times when it comes to privacy. The culprit, mostly, is Facebook. Since what was happening with Cambridge Analytica was discovered, more cases did not appear, such as Onavo VPN, owned by Facebook and acting almost like Spyware
Access after uninstalling the app would allow creators to show ads for the specific device that uninstalled it
But no it's just there and, obviously, it's not just Facebook playing with our data.Many of the times, different apps and websites use our data even without our consent. And now, Bloomberg has discovered that different apps on iOS and Android can keep track of our device even after being uninstalled.
Specifically, it seems, they use the information it gets to prompt us to reinstall the app. That is, using a tracker using silent push notifications, the removed app would generate a specific device ID.
Spotify is one of the apps that use the services of companies that use the uninstall tracker
Thus, when issuing the notification, if you get a response from our identifier it would mean that the app is installed. Otherwise, the company that issued the notification would not receive any response.In the latter case, they would activate the protocol trying to get us to reinstall it.
How would you do it? Using specific ads for our device identifier. Identifier generated by the cookies used by the applications and that allows certain ads to be displayed for the device that has said identifier.
We are talking about something quite serious in case it is confirmed that app developers have used this, since some of the companies that use the services of companies that offer this type of tracker (Adjust or AppsFlyer, among others) are companies as important as Spotify, T-Mobile, Telefonica, musical.ly or Yelp.
