SendX requires connection priivilege. Why?

I just installed SendX. I got pop up that where it showed the 'connection' privilege (first top group) to be allowed.

I understand that it needs the second group of privileges such as interconnection privilege for it to work to communicate between processes, but this privilege stays within the device. But why does it need access to internet, wifi, and GPS?

And if you change to deny internet, wifi, and GPS, it would send pop-up now and then to have those access allowed.

I am new with third-party apps. Anyone care to explain?

Thanks.

anybody?
