Overview

• Signal’s Windows 11 app now includes a 'Screen Security' feature, enabled by default, to prevent Microsoft Recall from capturing screenshots of encrypted chats.
• Microsoft Recall, an AI-powered tool that indexes continuous screenshots for searchable history, has faced privacy concerns since its 2024 introduction.
• Signal used a Digital Rights Management (DRM) flag, typically for copyrighted content, as a workaround due to Microsoft’s lack of developer opt-out tools for Recall.
• The feature may interfere with accessibility tools like screen readers, but users can disable it in Signal’s settings after a warning confirmation.
• Signal’s move highlights the tension between privacy-focused apps and OS-level AI systems, pressuring Microsoft to provide more granular developer controls.
