The Android Advertising ID is a unique ID in each Android device around which the all data collected from the same device is clustered. Infinia is able to identify the devices through the AAID and serve them profile based advertising.
By way of analogy, the AAID is like an advertising cookie in a web environment, which allows the advertiser to identify a device and display targeted ads.
There are several ways to prevent Infinia from collecting data from your device and using the AAID to show you advertising adapted to your inferred profile. The easiest way is asking Infinia to stop gathering data from your device. This will imply that you will not receive targeted advertising anymore from there on. You can easily send this request by this App, and you can also send Infinia the AAID of your device (that you will see in the main screen of this App) by sending an email to this address: firstname.lastname@example.org.
