about exec() / exec.php or url_fopen functions

Your plugin looks very popular and I want to use it on my website as well.

However, my hosting company disables all exec() / exec.php or url_fopen functions. The hosting company supports CURL as an alternative to url_fopen.
I did not find any answer from the forum. Do you mind telling me if your plugin uses exec() / exec.php or url_fopen functions or CURL?

Thank you for support!
