chrome extension called DatingAssistant (author: KOJΛK)

Hi everyone, I recently came across a Chrome extension called DatingAssistant (author: KOJΛK). It looks really well-made and exactly what I need. From what I could see in the manifest and code, it uses Plasmo framework and even connects to a Supabase backend for license verification. I’m not a developer, but I tried to dig through the code to find some contact info, a website, or anything about how to purchase a license/key — unfortunately, I couldn’t find any direct link, domain, or official sales page. Does anyone here know the author (KOJΛK) or how I could get in touch with them? I’d really like to buy a license and use this extension legally. Any hint, pointer, or contact would be greatly appreciated! Thank you 🙏
