Overview
Yuustudio ("this site") is committed to protecting the privacy of its users and complies with applicable privacy laws and regulations, including Japan's Act on the Protection of Personal Information (APPI) and, where applicable, the EU General Data Protection Regulation (GDPR). All web tools on this site are built on a Privacy by Design principle: user input data is processed exclusively inside the browser and is never transmitted to or stored on any server operated by this site.
Advertising — Google AdSense
This site uses Google AdSense, an advertising service operated by Google LLC (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA). Google AdSense may serve interest-based and behavioural advertising using first-party and third-party cookies (including the DoubleClick cookie). These cookies allow Google to identify your browser across sites and deliver ads that may be relevant to your interests based on browsing history. Under GDPR and Japan's revised APPI, cookie-based advertising relies on user consent or legitimate interest. You can opt out of personalised ads through Google's Ad Settings page (adssettings.google.com) or by disabling third-party cookies in your browser settings. For full details, see Google's Privacy Policy at policies.google.com/privacy.
Analytics — Google Analytics
This site may use Google Analytics 4 (GA4), a web analytics service provided by Google LLC, to understand how visitors interact with the site and to improve its content. Google Analytics collects data using cookies; all data is anonymised and aggregated — no personally identifiable information is collected. Data is transmitted to and stored on Google's servers with IP address masking applied. You can opt out by disabling cookies in your browser settings or by installing the Google Analytics Opt-out Browser Add-on available at tools.google.com/dlpage/gaoptout. For details, see the Google Analytics Terms of Service at marketingplatform.google.com/about/analytics/terms/.
Personal Information
Any personal information (such as your email address) submitted via the contact form is used solely to respond to your inquiry and will never be sold, rented, or disclosed to third parties. Collected personal information is stored securely and deleted after the inquiry is resolved. Furthermore, all tools on this site process data entirely client-side: no input data — including text, images, passwords, or any other user-entered content — is ever transmitted to or stored on any server.
Cookies
This site uses cookies for the following purposes: (1) Language preference — the NEXT_LOCALE cookie stores your selected language (Japanese or English) for one year so your preference is remembered on return visits. (2) Advertising — Google AdSense may set first- and third-party cookies to serve relevant ads, as described in the Advertising section above. (3) Analytics — Google Analytics may set cookies to collect anonymised usage data, as described in the Analytics section above. You can manage or disable cookies at any time through your browser settings. Disabling cookies may affect the language preference feature and the personalisation of advertisements.
