How to stop Catch Kathmandu Pro from "call home"

Hi, I'm new to WordPress and decided to buy your theme (Catch Kathmandu Pro) to benefit from all the features. I started working with the theme and noticed that every time I was making a change in the theme my WordPress tries to "communicate" with catchthemes.com. Since I am a paying customer can you please let me know where I remove the coding with the instructions to send information to your site? I could understand that happening in the free version, but in the paid one? Really? Thank you,
