WordPress o Jetpack ?

I don’t quite understand the translation of the question, but I’ll try my best to answer what I think you asked.

Jetpack is a plugin that adds several features to WordPress: https://www.ads-software.com/plugins/jetpack/ They can explain why you’d want to use it better on their site than I can in just text only: https://jetpack.com

If you have a WordPress site that you don’t want to communicate with Jetpack, simply deactivate and delete Jetpack from the Plugins section of your Dashboard.
