Install

1. In wp-admin, open Plugins › Add New and search for “NHR Database Cleaner”, or upload the plugin folder to /wp-content/plugins/.
2. Activate it.
3. Open Tools › Database Cleaner.

It needs WordPress 6.0 or later and PHP 7.4 or later, and nothing else. On multisite, network administrators also get Network Admin › Settings › Database Cleaner.

The plugin adds no database tables of its own. Deleting it removes its settings, schedules, history and snapshots, and never touches the data you managed with it.
