<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>
</ul>

<h3>Requirements</h3>
<ul>
<li>WordPress 5.9 or higher</li>
<li>PHP 7.4 or higher</li>
<li>ZipArchive PHP extension for file and full backups</li>
<li>mod_rewrite for optional staging password protection on Apache-compatible servers</li>
<li>Sufficient disk space for staging copies and backups</li>

<h3>Privacy</h3>
StageBridge runs locally inside your WordPress installation. It does not send site data to an external service.
The plugin stores settings, logs, backup metadata, operation progress, and staging metadata in the WordPress database. Backup archives and temporary job files are stored on your server under wp-content/uploads/stagebridge/. Email notifications are sent through your WordPress site’s configured mail system.
