Signal is stepping up privacy protections for Windows users with a new update that prevents the operating system from capturing screenshots of conversations. The encrypted messaging app’s latest “screen security” feature, enabled by default on Windows 11, specifically counters Microsoft’s controversial Recall function that continuously takes screenshots of user activity.
While Microsoft paused Recall’s rollout last year following backlash, the company recently resumed testing the AI-powered feature through its Windows Preview Channel. Signal remains concerned that even with Recall’s new opt-in requirement and pause capability, the feature still risks capturing sensitive chat content without user’s full awareness.
When activated, Signal’s screen security setting replaces actual chat content with blank screens in any attempted screenshots. However, the company cautions this may interfere with accessibility tools like screen readers. Users can disable the protection through Signal’s privacy settings, though the app requires confirmation to prevent accidental deactivation.
Signal’s move highlights growing tensions between privacy-focused apps and operating system features that automatically record user activity. As the company noted in a blog post: “Apps like Signal shouldn’t have to implement a ‘one weird trick’ to maintain privacy without proper developer tools”. This update represents the latest skirmish in the ongoing battle between user privacy and AI-driven system monitoring.
