Doubt about license purchased

I bought a single license, but I had a problem.
If I removed the copyright at the bottom, how did your company recognize my website?

What should I do now? After making a purchase on paypal I received the order number without email. This alone received nothing more.

Hi there

Hope you are having a good day and thank you for your question
We don’t need to recognize it, once you buy a license you can remove footer credit, that it, there is no other steps required in this agreement,
Thanks!
