Hi designerhajaa,

Welcome to Affinity Forums

There's no license keys for apps bought on the Mac App Store. The downloaded/installed app already includes an encrypted receipt associated with you Apple ID. If later you need to install it again on that or another computer you have, just run the Mac App Store, go to the Purchased tab on top and click the Install button in front of the app's name from the list below. Just make sure you are logged-in with the same Apple ID used to buy the application.
