Privacy Policy

Because there is no account registration feature, we do not collect identifying information such as names, phone numbers, or addresses. Access times and IP addresses are processed for visitor statistics; IP addresses are not stored in their original form but are converted into a one-way hash (SHA-256) value used only to detect duplicate visits within a day.

If you contact us by email, the sender's email address and the content of the inquiry are processed in order to respond and address any corrections. This information is not used for any purpose beyond handling the inquiry.

For convenience of use, this site uses the browser's local storage (localStorage/sessionStorage). This includes settings such as 'don't show today' for notice pop-ups and duplicate-visit deduplication; these values are stored only in the browser and are not transmitted to any server.

You may block or delete cookies and site data in your browser settings. Doing so may disable some convenience features (such as pop-up dismissal settings), but does not restrict access to content.

This site may display third-party advertising, including Google AdSense. Google and other third-party ad vendors use cookies to serve ads based on a visitor's prior visits to this site or other sites.

Users may opt out of personalized ads in Google Ads Settings (https://adssettings.google.com), and may also opt out of third-party vendors' cookie use in bulk at www.aboutads.info. For users in the European Economic Area (EEA), the UK, and Switzerland, consent procedures under Google's EU user consent policy apply.

Google Analytics and Google Tag Manager may be used for traffic analysis. The information collected in this process is de-identified statistical information such as page views, referral sources, and device/browser type, and is processed according to Google's privacy policy.

Hashed values and daily aggregate figures used for visit statistics are retained only within the scope needed for statistical purposes, and the original IP cannot be reconstructed from the hash to identify an individual. Email inquiry records are deleted once there is no further need to retain them after processing is complete.

The retention period for data collected and stored independently by third-party advertising and analytics tools follows the respective provider's own policy.

Users may request to review how their information is being processed, request that processing be suspended, or request deletion. Requests should be sent to the email address below and will be processed without delay upon confirmation.
