Privacy Policy

Machikarte uses Google Analytics 4 (GA4) to measure site usage for service-improvement purposes. We collect the following information.

• Page views and URLs of pages visited
• Time on site and navigation paths within the site
• Approximate location of access (prefecture / country level)
• Device type and browser type

All of the above is aggregated, anonymized information. We do not collect information that identifies a specific individual.

Machikarte uses cookies to enable Google Analytics 4. Cookies are small text files stored by your browser; they are not used to personally identify visitors.

Google Consent Mode v2: To manage visitor consent, the cookie banner offers the following toggles. Storage access is granted only after "Accept" is selected.

• analytics_storage: cookie storage for site analytics (GA4)
• functionality_storage: cookie storage for maintaining site functionality
• security_storage: cookie storage for security purposes
• ad_storage / ad_user_data / ad_personalization: advertising-related consent flags (Machikarte does not currently serve advertising, but these flags are transmitted as required by Consent Mode v2 — they are kept in reserve in case Google Ad Grants or similar are considered later)

You can disable cookies via your browser settings, although some site functions may stop working correctly.

If you want to opt out of Google Analytics tracking, please use the Google Analytics Opt-out Browser Add-on.

Machikarte does not collect personally identifying information such as name, email address, or postal address.

When you contact us, any name, email, or other information you include in your message is used solely to respond to your inquiry and for no other purpose.

Data retention: information received via our contact form is retained for one year after the final reply, and then deleted. GA4 access logs are retained for 14 months (Google's default setting).

User rights: under Japan's Act on the Protection of Personal Information, you may request access to, correction of, or deletion of personal data we hold. Please submit requests via the contact form. We respond within two weeks as a rule.
