The leadership of the Children, Youth and Families Department (CYFD) has directed staff to use Signal, a secure communication app, and has set chats to automatically delete. In contrast to standard text messages or emails — which could be accessed by attorneys, reporters and members of the public under the state’s open records laws — messages sent via Signal are all but impossible to retrieve. Once deleted, virtually no trace of a Signal conversation remains, even on the company’s server.
