原文外掛簡介
Mega Database Cleanup is a modern, high-performance cleanup utility built to remove unused, empty, bloated, or orphaned metadata from your WordPress database — safely and automatically.
It includes a smart scanner, preview mode, ACF pattern cleanup, scheduled tasks, and full backup support. Ideal for site owners, developers, agencies, and power users who want a faster & cleaner database without risking important data.
Version 2.0.0 introduces a completely rewritten modular architecture, a real-time Health Dashboard, and targeted cleanup modules for post revisions, trash, spam comments, and expired transients.

Privacy Policy
Mega Database Cleanup is committed to transparency regarding user data:
No external data transmission — No information ever leaves your site.
Activation popup (optional) — If you enter your email in the welcome popup, it is saved to your site’s wp_options table (mdbcp_subscriber_email). It is never sent to any third-party server. You can skip this step entirely.
Deactivation feedback (optional) — If you submit a deactivation reason, it is saved locally to your site’s wp_options table (mdbcp_deactivation_log). It is never sent externally. You can skip this step entirely.
Database backups — Backup data is stored in a dedicated custom table on your own database server.
