<h3>External Services</h3>
This plugin communicates only between your own WordPress sites when pushing or pulling posts. No data is routed through any third-party server.
<ul>
<li>What is sent: post content, post meta, and media attachments belonging to the post being synced</li>
<li>Where it goes: directly to the remote WordPress site URL you configure in Settings</li>
<li>Authentication: requests are authenticated with a secret key you set — no external accounts required</li>
