"The app is permanently removed from your Mac the next time you or the Finder empties the Trash. If you have files that you created with the app, you may not be able to open them again. If you decide you want to keep the app, get it back before emptying the Trash—select the app in the Trash, then choose File > Put Back."
We hope that helps. Take care!
