Privacy-focused messaging platform Signal is pushing back against Microsoft’s controversial Recall feature, implementing a system-level defense that prevents the AI-powered tool from capturing screenshots of private chats on Windows 11.
According to a report by BetaNews, Signal has activated a Windows-specific “Screen security” setting by default, which utilizes a DRM flag to blackout the app’s content during screen capture attempts. The feature works similarly to the way streaming services prevent screenshots of protected video content—by showing only a black screen instead.
“Microsoft simply hasn’t given developers any real way to exclude their apps from Recall’s data vacuum,” Signal said in a statement. “So the company had to use the same DRM mechanism Microsoft applies to movies and TV shows.”
Recall, originally announced during Microsoft’s Copilot+ PC initiative, takes automated screenshots every few seconds and compiles them into a searchable timeline. While pitched as a memory aid for users, the feature has drawn criticism from privacy advocates and security experts, many of whom argue it creates serious data exposure risks.
Although Microsoft initially pulled Recall following backlash, the feature has returned in newer Windows builds, sparking concern among developers who handle sensitive user data. Signal’s latest move is a preemptive measure to prevent Recall from violating the core privacy principles on which the app is built.
While the new screen security feature may affect users who rely on accessibility tools such as screen readers, Signal acknowledges the trade-off and maintains that Microsoft’s lack of granular controls leaves developers few alternatives.
Adding to the frustration, Signal points out that Microsoft already exempts private browser windows from Recall but fails to extend that same consideration to messaging apps—raising questions about Microsoft’s priorities when it comes to user privacy.
With this update, Signal is drawing a clear line: protecting user privacy should never require workarounds, and messaging apps deserve the same protections as web browsers.
