Detect reinstalls without depending on advertising IDs. This is done by storing the last app install date on the secure local storage in the device (in iOS, the Keychain).

Note: Only the last app install date is stored in the device's local storage for this purpose - no other device identifier (e.g., IDFA, IDFV) is stored.
