Cookie Policy

We use only the cookies required to display the site and run its basic functions. Blocking them prevents features such as sign-in from working.

Authentication cookies and browser local storage keep you signed in. They are removed when you sign out.

Your language choice (Japanese or English) and theme choice (system, light or dark) are stored in browser local storage so they apply on your next visit. This information is not sent anywhere.

We currently use no analytics cookies and no advertising cookies. If an analytics tool is added later, this page will be updated to explain its purpose and how to manage it.

You can delete or restrict cookies and local storage in your browser settings. Deleting authentication cookies signs you out, and blocking them may prevent sign-in.
