Appliers have been wondering how to decide who uninstalls the software and possibly directs them to ads that prompt them to reinstall Bloomberg reports.
A number of track technology providers offer uninstall tracking, which usually works with so-called silent push messages. They are designed to allow apps to update information without actually posting a message, but by monitoring which previously installed app instances do not recognize these messages, companies can distinguish who has taken apps from their phones. Then you can use the unique advertising IDs associated with each phone. They can direct them to messages that prompt them to reinstall.
Tracks may violate Apple and Google policies for iOS and Android, but Bloomberg reports neither the Company commented on the matter.
It seems that it is against users’ expectations that apps will stop tracking when they are away from the phone, although the loophole only delivers software companies a final piece of information.
