    You can get the UDID of the user’s device (see: How can I retrieve the UDID on iOS?).

    Then, you can send a hash (e.g., SHA256) of the UDID to your server whenever the lite version is launched. Whenever your full version is launched, you can send the same ping. Since the UDID is the same, the hash will be the same.

    On your server, you can read from your database and see that hash ABCXYZ has launched both the lite and full versions of your games.
