>, it has to be stored somewhere, pending delivery. I think the "stored?" question isn't about the minimal fraction of time notifications have to be in transient storage to even "send and immediately forget". Yes, a transitory "message queue pub/sub" architecture still needs to have some notion of "storage" to work. Instead, "stored?" is wondering about a company's discretionary and optional retention period after the successful notification delivery that isn't required by law. E.g. 30 days?, or 1 year?, or longer? ... such that those archive records of past notifications have become targets for court subpoenas and law enforcement information requests. If Apple doesn't "store" notifications in this sense, there's nothing to "hand over".
