I'm curious about the last paragraph relating to Signal. How, exactly, have Brave managed this without also blocking screenshots? Is there a flag Signal missed?
replies(3):
Windows lets browser apps (more technically, apps that have an `http` or `https` protocol handler registered) to use `SetInputScope` function to set `IS_PRIVATE` for a window. We were able to use that and have it apply for all Brave windows, and thus granularly turn off Recall without affecting non-Recall screen readers or screenshot capabilities.
Signal doesn't have protocol handlers for `http` and `https`, so it can't do the same.
