How to recover my purchased license after reinstalling macOS

Hi, I've already purchased a license before. But lately I had to completed reinstall my macOS from scratch. After that, BetterTouchTool will not recognize my machine anymore. My question is, how can I recover my purchased license without paying for it again? thanks!

Hey,

please send a short email to andreas@folivora.ai with your details (e.g. emails you may have used for the purchase). Then I can look it up and re-send the license to you.
