This article explains what the plugin sends, what it stores and what it loads.
What the plugin sends
Nothing. The plugin makes no request to Japan Post or to any other service. When a customer types a postcode, their browser loads a small data file from your own site’s plugin folder, the same way it loads the site’s images and scripts.
What the plugin stores
Nothing. It creates no database table, saves no setting and sets no cookie. The addresses customers enter are saved by WooCommerce as usual, with the order or the customer’s account.
Remote scripts and fonts
None. The plugin’s scripts and its postcode data all ship with the plugin.
