SKAdNetwork: Redownload is per device or per Apple ID?

SKAdNetwork postback will send "redownload" value. Is it calculated based per Device or per Apple ID?


Redownload is determined by Apple ID. Once an Apple ID has purchased the content on any device the application will be in its purchase history and any subsequent app installs are treated as redownloads.

When a user A installs application B for the first time through an advertisement X published in an application, SKAD returns a postback to say that there was an Install.

If this same user A with the same Apple ID uninstalls the application B and redownloads it to open it and repeats this action 5 times, does SKAD return 5 Postaback containing 5 Re-Installs?
