Signal received a grand jury subpoena for user data in the Central District of California, but the company was unable to provide the requested information due to its end-to-end encryption. The subpoena requested data such as the user's name, address, and correspondence, but Signal only provided Unix timestamps for when the account was created and last connected. This is not the first time Signal has received such a subpoena and been unable to provide the requested data. The company has committed to continuing to protect user privacy and working with organizations like the ACLU to respond to government requests.
