Privacy Policy

This Privacy Policy explains how YAMATERRA ("the Site", https://yamaterra.com) handles information. By using the Site you agree to this policy. The Japanese version is the original; this English translation is provided for convenience.

1. Operator

The Site is operated by an individual (YAMATERRA). For inquiries, please use the contact form.

2. Information we collect

The Site does not require account registration and does not intentionally collect personally identifiable information. For usage analysis we collect anonymous access data (such as page views, approximate region, device and browser type) via the analytics tools described below. Your viewing history and display settings are stored only in your browser.

3. Cookies & local storage

The Site uses cookies for analytics and advertising (see below). Your recently viewed mountains and display preferences are saved in your browser's localStorage only and are not transmitted externally. You can disable cookies in your browser settings; some features may then not work. You can also opt out of our analytics on this site by visiting any page with ?noga=1 appended to the URL (re-enable with ?noga=0).

4. Advertising & affiliate programs

The Site may display advertising through Google AdSense, a third-party ad service. Google and its partners may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalized advertising in Google Ads Settings, or opt out of third-party cookies at aboutads.info.

The Site also participates in affiliate programs (e.g., Amazon Associates, Rakuten Affiliate and others). When you click an affiliate link and make a purchase, the Site may earn a commission at no additional cost to you.

As an Amazon Associate, YAMATERRA earns from qualifying purchases.

5. Analytics

The Site uses Google Analytics 4 and Microsoft Clarity to understand how the Site is used. These tools use cookies and may collect anonymized usage data. Google Consent Mode v2 is enabled; in the EEA/UK, measurement is denied by default until consent. You can opt out using the Google Analytics Opt-out Add-on or the ?noga=1 switch described above.

6. Transmission to external services
