Updates publication dates so lists and feeds see newer timestamps. Each post, page, or product waits your chosen time after its publish date, then can auto-update. WP-Cron only checks for due items every so often (hourly / twice a day / daily), which is separate from “yearly per post.”
What gets republished
Only post-like content: Posts, Pages, Products (WooCommerce), and any other public post type registered by themes or plugins. Categories, tags, and other taxonomies are not separate targets—the plugin does not “republish” terms.
Highlights
<ul>
<li>Schedule — On/off and wait after publish date (hourly … yearly). New installs default to Quarter (Recommended) (~90 days).</li>
<li>Configure — Choose which public post types are included and how many items run per batch (Advanced).</li>
<li>Per item — On each post/page/product (etc.), override: follow site default for that type, force ON, or force OFF. Republish now for immediate date bump on published items.</li>
<li>Safe defaults — New custom post types appear in settings turned off until you enable them.</li>
</ul>
Important
<ul>
<li>Republishing sets published and last modified times to the republish moment. It does not rewrite body content.</li>
<li>Uses GMT publish time. Bumps may trail the due moment by up to one cron check.</li>
<li>WP-Cron needs traffic; use server cron + <code>wp-cron.php</code> for steady timing.</li>
</ul>
<h3>Privacy</h3>
<ul>
<li>Stores settings in the WordPress options table (<code>wapr_options</code>, <code>wapr_scheduler_sig</code>).</li>
<li>Stores per-post choice in post meta (<code>_wapr_republish</code>) when not using the default.</li>
<li>Does not send data to external services, analytics, or tracking endpoints.</li>
<li>Scheduled work runs via WordPress’s own WP-Cron on your server.</li>
</ul>
