How do apps recognize your device?
The apps can track you by linking your Advertising ID — a unique but resettable number used to tailor advertising — with other identifiers on your phone that are difficult or impossible to change. Those IDs are the device’s unique signatures: the MAC address, IMEI and Android ID.
Can you tell when you downloaded an app?
Under the “All” tab, you’ll see all of the apps you have ever bought or downloaded using your current Apple or iCloud ID. This will also show you the date the app was downloaded.
