Thank you. Your licence is on its way.
Paddle has your receipt, and the key is being emailed to the address you paid with. It usually lands within a minute. If it has not arrived in ten, check the spam folder, then write to support@bredo.app and it will be reissued.
Entering the key
Open Bredo, go to Settings, then Licence, and paste the key. It is checked on your Mac: no sign-in, no activation server. Keep the email, since the key is the licence.
Don't have Bredo yet? Download it here — the key goes into the same copy you would have tried. Trouble with the key, or the email?
