This made the government through a subpoena, or a summons , to Open Whisper Systems, the organization behind Signal. This Open Whisper Systems replied that one of the two numbers is known to the service. The only relevant information with respect to that number can provide, the creation date of the account and the last time with the account connection to the Signal servers.

Open Whisper Systems adds not be able to provide additional information, as it does not hold there. The ACLU, representing the Signal-makers in the case, writes that the government together with the subpoena also imposed a gag order for the duration of one year. The reason was that information about the existence of the subpoena could bring ongoing investigations in serious danger, the government said. The civil rights movement has made order to oppose this gag, so the documents are now partly in. Typically, companies will request by the US government keep secret.

Also frequently orders would be imposed no time limit, unlike the order to Open Whisper Systems.
