app exclusion apis

The app exclusion APIs tag covers discussions about application programming interfaces that allow software to opt out of system-level monitoring or data collection on Windows. A prominent example is Signal's Screen Security feature on Windows 11, which uses such APIs to block Microsoft's Recall tool from capturing screenshots of Signal conversations. This highlights the role of app exclusion APIs in enabling developers to protect user privacy against increasingly intrusive operating system features, particularly those leveraging AI. The tag is relevant for developers and privacy-conscious users interested in how applications can assert control over their data within the Windows ecosystem.
