wp_add_privacy_policy_content() WP 4.9.6

Helper function for adding content to the Privacy Policy Guide.

Plugins and themes should suggest text for inclusion in the site's privacy policy. The suggested text should contain information about any functionality that affects user privacy, and will be shown on the Privacy Policy Guide screen.

A plugin or theme can use this function multiple times as long as it will help to better present the suggested policy content. For example modular plugins such as WooCommerse or Jetpack can add or remove suggested content depending on the modules/extensions that are enabled. For more information see the Plugin Handbook: https://developer.wordpress.org/plugins/privacy/suggesting-text-for-the-site-privacy-policy/.
