Grand jury subpoena for Signal user data in the United States District Court for the District of Columbia

06 Mar 2026

Signal end-to-end encrypts both content and metadata by default far beyond most of our peers. Our aim is to have access to as close to no data as possible, meaning that we have a fraction of the personal information compared to the average communications service. We simply don’t have access to things like messages, calls, profile information, group information, contacts, stories, call logs, and many other kinds of content and metadata, and we cannot share data in response to valid legal requests that we never had in the first place.

27 Apr 2021

It’s the first half of 2021 – nearly five years since the “first half of 2016” – but in many ways not much has changed. The United Kingdom is still trying to figure out Brexit, another Justin Bieber song hit #1 on the charts (is it too late now to say sorry?), and Signal still doesn’t really know anything about you.

Grand jury subpoena for Signal user data, Eastern District of Virginia

04 Oct 2016

In the “first half of 2016” (the most specific we’re permitted to be), we received a subpoena from the Eastern District of Virginia. The subpoena required us to provide information about two Signal users for a federal grand jury investigation.

We’ve designed the Signal service to minimize the data we retain about Signal users, so the only information we can produce in response to a request like this is the date and time a user registered with Signal and the last date of a user’s connectivity to the Signal service.
