​Signal has updated its Windows app to protect users' privacy by blocking Microsoft's AI-powered Recall feature from taking screenshots of their conversations.

This new privacy feature, dubbed "screen security," is now enabled by default on all Windows 11 devices, where Recall continuously takes screenshots of all active windows every few seconds and analyzes them to build a database that can be searched using natural language.
