The #1 thing to check first

On every platform, "installed" and "protected" are two different things. If Guardrail seems installed but isn't doing anything, this is almost always why:

PlatformInstall methodPermission Guardrail needs to actually work
WindowsSigned .exe, one UAC prompt during installNone extra — works right after install
macOS.dmg, drag to Applications (Apple Silicon only)Accessibility and Screen Recording, both in System Settings
AndroidGoogle Play StoreAccessibility Service (required); overlay & notifications recommended
