A: Hi Anthony,

I think you are right, so we changed the root domains https://aflip.in and https://hflip.co to load a generic error page without any brand instead of the redirection.

Besides that, bear in mind that someone with technical knowledge could analyze the website's source code to find out how it was created. So if you need to be extremely sure your customers don't know how you made the flipbook, the best option is to download the Html source code of the flipbook and upload it to your web-hosting, changing any reference or clue you find in the code.
