Log out of (remove) a self-hosted WordPress
If it’s a self-hosted site you can only remove the site from the app by going to the Settings tab and clicking on the Remove Site option or disconnect it from Jetpack but this will not actually delete the site from the web. To do that you would need to contact your host.
