How can I find license

I purchased a lifetime license of BTT close to over a year ago. I'm not sure how to find my license key at this point but would like to use on a new Mac. Thanks!

I'm in the exactly same situation and would like an answer. Is the solution still to send an email to Mr. Andreas? Thank you in advance!

Yep, just email him. I've stored mine in an online drive now :sweat_smile:
