常见问题:
Does this delete important data?
No — the plugin only targets metadata that is clearly empty, unused, or orphaned.\ If backup is enabled, you can restore deleted rows 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.
Can I add my own patterns?
Absolutely. You can add or remove SQL LIKE patterns directly from the admin panel.
Does it work on multisite?
Yes, it works on standard and multisite installations. Cleanup runs per site.
Will this improve my website speed?
Yes — removing thousands of empty meta rows reduces database size and speeds up queries.
What if I delete something by mistake?
If backups are enabled, deleted metadata is stored in a dedicated table so you can manually restore it via phpMyAdmin.
How safe is the scheduled cleanup?
Very safe — it follows the same rules as manual cleanup, including retention rules and backups.
Does the plugin collect any personal data?
Only if you choose to enter your email in the activation popup. That email is stored locally in your own WordPress database (wp_options table) and is never transmitted externally. You can skip this step entirely — it is 100% optional.
What is the deactivation feedback popup?
When you deactivate the plugin, an optional modal appears asking for a brief reason. All responses are stored locally in your wp_options table only. No data is sent to any remote server. You can skip it with one click.
