Use of the app, including opt-in tracking of a user's location inside its stores and elsewhere, implies consent to allow Target to use personal information that it says "may" be shared with third parties, such as companies outside of Target, for their marketing purposes directed at the app user.
When a user turns on location sharing in the app, Target will use GPS and Wi-Fi outside its stores and beacons and Bluetooth, LED light chip and other technologies inside its store that "permit Target to do things like find nearby products for you, get you real-time deals and auto-sort your shopping list."
The policy also describes various opt-out capabilities in the app, including to opt-out of geo-location and in-store location. There's also the ability to uninstall the entire app, but Target notes that if a user uninstalls the app, the Target unique identifier associated with the user's device will still be stored. If the user re-installs the app on the same device, Target will be able to re-associate the identifier with previous transactions.
Target also says it will retain a customer's information as long as the application is in use "and for a reasonable time thereafter."
Reality check: Are beacons vulnerable to attack?
It is highly unlikely beacons will be hacked directly, any more than individual smartphones or smartwatches, analysts say. The main concern about data gathered by retailers through beacons or directly from smartphone apps is that the data will be stored by various parties on servers that are then vulnerable to attack.
