The use of SilverPush to track users across multiple devices has privacy implications and allows for more detailed tracking of users. Data can be collected from multiple devices used by a single user and correlated to form a more accurate picture of the person being tracked.
In April 2014, Geektime reported that SilverPush had raised $1.5 million in funding to increase global reach.
In July 2014, TechCrunch reported that SilverPush was using "ultrasonic inaudible sounds" called "audio beacons" along with cookies to reliably track users across multiple devices and that devices with an app containing the SilverPush SDK are constantly listening for audio beacons.
In April 2015, SilverPush claimed 67 apps were using its code.
In March 2016, the FTC issued warning letters to 12 app developers using SilverPush code in their apps. The FTC warned these developers that they may be violating the FTC Act if they state or imply that their apps are not tracking television viewing habits when they in fact are. Shortly after the FTC warning, SilverPush made an official statement that they are ending the Unique Audio Beacon service. However, as of 21 March 2016, SilverPush is still advertising Unique Audio Beacon on their website.
In November 2016, researchers from UCL, UCSB and PoliMI demonstrated the security and privacy implications of the ultrasound cross-device tracking (uXDT) technology used by SilverPush. The most notable of their attacks uses uXDT-enabled applications to deanonymize Tor users.
In May 2017 SilverPush technology was again the subject of research: "A team of researchers from the Brunswick Technical University in Germany discovered  Android apps that employ ultrasonic tracking beacons to track users and their nearby environment. Their research paper focused on the technology of ultrasound cross-device tracking (uXDT)."
