Update: Since publishing, Barnes & Noble has responded to us to confirm that a software update has been pushed to all NOOK devices prior to sales with a newer version of ADUPS (5.5) which does not break Google’s security requirements. ADUPS further confirmed that no user data was transmitted from any NOOK 7 units. Barnes & Noble is also working on an update that will completely remove ADUPS from the tablet.
NOOK Tablet 7” went on sale on November 26. By that time, the device automatically updated to a newer version of ADUPS (5.5), which has been certified as complying with Google’s security requirements, when first connected to Wi-Fi. ADUPS has confirmed to Barnes & Noble that it never collected any personally identifiable information or location data from NOOK Tablet 7” devices, nor will it do so in the future.
Finally, we are working on a software update to remove ADUPS completely from the NOOK Tablet 7”. That update will be made available to download within the next few weeks, but in the meantime customers can rest assured that the device is safe to use.” – Fred Argir, Chief Digital Officer"
