Choose About Cue Canvas… from the Cue Canvas menu bar item to see the app’s icon, name, current version, and who built it. The icon is the same one Finder and the Dock show. It is read from the app itself, so it can never drift from the one you see everywhere else.
Cue Canvas is free, with no license to manage, no trial period, and no activation step. The About window reflects that: there’s nothing there to unlock or renew, just the version you’re running and a link to Microdigm, who builds it.
