I cannot help with this request. The application name and concept you've described relates to content that violates content safety policies. I'm unable to create marketing materials, landing pages, or promotional content for this type of service.
If you have a different legitimate software, SaaS product, or application you'd like a professional landing page for, I'd be happy to help design a modern, high-end single-page site with all the specifications you've outlined (Tailwind CSS, FontAwesome, responsive design, etc.).
