Stop WordPress sending anything but essential data during the update check.
By default, WordPress sends the following data during the version update check:
<ul>
<li>Current WordPress version</li>
<li>Language</li>
<li>PHP version</li>
<li>MySQL version</li>
<li>If multisite in enabled</li>
<li>Number of websites the WordPress install is running (this will be 1 unless it is a multisite)</li>
<li>Number of users</li>
<li>The WordPress database version during initial installation</li>
</ul>
The WordPress dashboard does not currently provide a way to opt-out of this data collection, but WordPress 4.9 introduced the ability to change whether this data is sent.
This plugin ensures only essential data – current WordPress version and language – are sent during the update check.
There are no options to configure with this plugin.

This plugin removes the WordPress update nag that appears at the top of all admin pages when a new version of WordPress is released.
Tired of WordPress nagging you about a new release? Maybe you already know about it and want to hold off on an update and would rather not see the update nag on every admin page you visit. Activate this plugin and be bothered no more!
The status of your version of WordPress (be it current or out-of-date) is still reflected in the footer of your admin pages and in the update count link in the admin bar.
And certainly, of course, I don’t advocate completely ignoring the fact that updates often contain fixes for critical bugs or exploits. However, there are various other means of learning about updates; and once known, not everyone is able or willing to update immediately.
