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. #### Highlights * **Health Score Dashboard** Real-time visual representation of your database health and performance at a glance. [NEW in 2.0.0] * **Targeted Cleanup Modules** Fast, one-click optimization for Post Revisions, Trashed Content, Spam Comments, and Expired Transients. [NEW in 2.0.0] * **Empty / Unused Meta Scanner** Detects empty, null, serialized-empty, or JSON- empty metadata across Post, User, Term, and Comment tables. * **ACF Cleanup Engine** Automatically identifies patterns used by Advanced Custom Fields to detect orphan entries. * **Safety Vault System** Automatically secures deleted revisions and junk data in a temporary vault for easy recovery. [NEW in 2.0.0] * **Snapshot Management** Create manual snapshots of your metadata before cleanup and restore them whenever needed. [NEW in 2.0.0] * **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 / snapshot. * **Scheduled Cleanup (WP-Cron)** Cleanup can run automatically (daily, weekly). * **Retention Rules** Keep the latest N meta rows per meta_key (default: 3). * **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 optimization tips and anonymous diagnostic sync. * **Deactivation Feedback** If you deactivate the plugin, an optional feedback popup appears so you can share why. #### Who Is This For? **Website Owners** – Improve site performance and reduce database size safely. **Agencies & Developers** – Maintain clean data structures, especially on large sites. **ACF Users** – Automatically remove leftover fields that accumulate over time. **Performance Optimizers** – Speed up queries by removing thousands of useless meta rows. #### Why Mega Database Cleanup Is Different * Designed for **large databases** * Uses safe preview mode * Runs scheduled cleanups automatically * Creates a backup of every deleted row * **Safety Vault** prevents permanent loss of revisions and trashed data * Preserves the **Latest 3 entries** for absolute safety * 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. ### Developer Hooks #### Filters * `mega_db_cleanup_patterns` – Modify cleanup patterns * `mega_db_cleanup_retention_limit` – Change default “keep latest N” count #### Actions * `mega_db_cleanup_before_delete` – Fires before deletion * `mega_db_cleanup_after_delete` – Fires after deletion ### Credits Developed with ❤️ by [MegaWix Technologies](https://www.megawix.com) * Plugin Development: MegaWix Technologies * Testing & QA: MegaWix Technologies ### Support Need help?

No — the plugin only targets metadata that is clearly empty, unused, or orphaned. With the new Safety Vault and Snapshot systems, you can restore deleted data at any time. ### Is there a preview mode? Yes. Preview mode allows you to see exactly which meta rows are considered empty before removing anything. ### Does this support ACF fields? Yes! It includes a dedicated ACF cleanup engine that uses pattern rules to identify real orphan fields. ### What is the Health Score? It is a percentage-based calculation that tells you how optimized your database is based on the amount of junk data found. ### What if I delete something by mistake? If backups/snapshots are enabled, deleted metadata is stored in a dedicated table so you can restore it from the plugin dashboard. ### How safe is the scheduled cleanup? Very safe — it follows the same rules as manual cleanup, including retention rules and backups. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Mega Database Cleanup” is open source software.
