Mega Database Cleanup

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.

Highlights

• Empty / Unused Meta Scanner
  Detects empty, null, serialized-empty, or JSON-empty postmeta values.

• ACF Cleanup Engine
  Automatically identifies patterns used by Advanced Custom Fields to detect orphan entries.

• Real-Time Safe Preview
  See exactly what will be deleted before confirming cleanup.

• Backup Before Delete
  All removed metadata can be stored in a dedicated backup table.

• Scheduled Cleanup (WP-Cron)
  Cleanup can run automatically (hourly, daily, weekly).

• Retention Rules
  Keep the latest N meta rows per meta_key (default: 5).

• Safe & Secure
  Full validation, sanitization, and capability checks included.

• One-Click Full Cleanup
  Delete unused metadata across the entire database.

• Custom Cleanup Patterns
  Add or remove ACF-like patterns (SQL LIKE rules).

• Activation Welcome Popup
  On first activation, optionally subscribe to plugin update tips. Email is stored locally on your site — never shared externally.

• Deactivation Feedback
  If you deactivate the plugin, an optional feedback popup appears so you can share why. All responses are stored locally on your site only.

Why Mega Database Cleanup Is Different

• Uses optimized SQL queries for predictable performance

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.

All data collection is opt-in, clearly disclosed, and stored exclusively within your WordPress installation.
