Privacy Policy

This English version is a translation provided for reference. If there is any difference between this version and the Japanese version, the Japanese version prevails.

The operator of this website (the "Operator") handles information about people ("Users") who use this website and the services the Operator provides through it (collectively, the "Service") as described below.

If an individual service handles information differently from this policy, that difference is described on its page or in the description of the distributed software, and that description takes precedence over this policy.

  • Pages viewed, display language, and the domain name of the referring site
  • Device type, country of access, and date and time
  • A session identifier
  • Actions taken in the Service and their results

2. Information Stored in Your Browser

The Service stores information about how the Service is used, as well as settings, in the User's browser (such as local storage). Users can delete it from their browser settings.

3. Purposes of Use

  • Understanding how the Service is used and compiling statistics
  • Responding to misuse and technical problems

4. Storage Location and Retention Period

Usage records are stored using services provided by Cloudflare, Inc. As a general rule, records are kept for 13 months and are deleted after that period.

5. Disclosure to Third Parties

The Operator does not provide collected information to third parties except in the following cases. This does not apply to information that has been processed into statistics and cannot identify Users.

6. External Services

This website is delivered using services provided by Cloudflare, Inc. In the course of delivery, Cloudflare may process communication data such as IP addresses.

This website uses Google AdSense, a third-party advertising service. Third-party vendors, including Google, use cookies and similar technologies to serve ads based on Users' prior visits to this website and other websites. In doing so, information such as the URL of the page viewed, identifiers such as cookies, IP addresses, and browser information is sent to Google.

Users can opt out of personalized advertising in Google's Ads Settings. For how Google handles information, please see Google's policies.

7. How to Stop Sending Usage Records

Turning on "Do not send analytics" with the switch at the bottom of this page stops that browser from sending usage records. Records are also not sent when Global Privacy Control is enabled in the browser. This switch does not apply to advertising.

8. Changes to This Policy

The Operator may revise this policy as necessary. The revised policy takes effect when it is posted on this page.
