Information and purposes

The server may record technical information such as IP address, access time, requested URL, and browser details. We use it to prevent misuse, investigate failures, secure the site, and improve its content.

Information submitted through the linked support form is used to answer requests, verify identity where needed, prevent abuse, and improve products and services.

Cookies, storage, and analytics

Your cookie choice is stored in your browser's localStorage. This is necessary to remember the setting and is not used for advertising.

Google Analytics is not loaded by default. It is loaded only after you choose “Allow access analytics,” and is used to understand traffic and improve content. We do not use Google Signals or analytics data for advertising. Refusing analytics does not prevent you from reading the site or using the plugin.

Service providers and international transfers

If you allow analytics, information needed by Google Analytics is sent to Google and may be processed outside your country. Review Google's privacy policy for details.

The site is hosted by Xserver in Japan. We do not sell collected information. We may disclose information when required by law or when necessary to protect life, safety, security, or legal rights.

Retention and security

Server logs are kept for the period needed for security, troubleshooting, and backup operations. Your cookie choice remains until you clear the relevant browser storage. Records may be kept longer where required for legal claims, security, or fraud prevention.

Your rights

You may use the privacy contact above to request access, correction, deletion, restriction, or to object to processing of information about you. We may request reasonable proof of identity. We may retain records required by law or needed for security, fraud prevention, or legal claims, and will explain when a request cannot be fully completed.

Changes

We may update this policy as services or legal requirements change. Material changes will be described on this page.
