Six steps to remove the app, the layouts it saved, its preferences, and the permission it asked for. No uninstaller required.
Managed Macs need the deployment path: PPPC and Accessibility.
Click the TrackStudio icon in the menu bar and choose Quit. If the icon is hidden by menu-bar overflow, quit it from Activity Monitor.
Open Applications, drag TrackStudio to the Trash, and empty it. If you installed with Homebrew, run brew uninstall --cask trackstudio instead.
Your layouts live in ~/Library/Application Support/TrackStudio/. Delete that folder to remove scenes and gestures. Export anything you want to keep first.
Preferences are stored under the app identifier. Delete ~/Library/Preferences/xyz.trackstudio.app.plist and ~/Library/Caches/xyz.trackstudio.app if they exist.
Open System Settings, Privacy & Security, Accessibility, select TrackStudio, and remove it with the minus button. Do the same in Input Monitoring if the app appears there.
Your key is yours. Reinstalling later and pasting the same key activates the app again; there is no deactivation step.
The license is an offline key, not a subscription. Removing the app does not cancel anything because there is nothing to cancel. Reinstall later and the same key works.
Menu-bar apps can leave a login item behind. Check System Settings, General, Login Items and remove TrackStudio there. If a gesture still fires, confirm the app is gone from Applications and that no copy exists in another folder.
If you are reinstalling, the trial and the license both work the same way as before.
