Privacy Policy

This policy explains how information about visitors is handled on Numlino ("this site"), across both its Japanese and English pages. When a language version is added, this policy is updated.

Numbers you enter into a calculator

Calculations are performed in your browser. The calculation programs of this site contain no processing that sends the numbers you enter to this site's servers or to external services, or that stores them in cookies or in the browser's storage (such as local storage). For measurement by Google Analytics, which is loaded on the Japanese pages, see the next section.

Analytics (Google Analytics)

The Japanese pages of this site use Google Analytics (GA4), a web analytics service provided by Google LLC. When you view a Japanese page, your browser loads the Google Analytics program from Google's servers, and Google Analytics measures how this site is used. Google Analytics uses cookies and similar storage for this measurement. For what is collected and how it is used, see Google's privacy policy and "How Google uses information from sites or apps that use our services".

The English pages do not currently use Google Analytics.

Consent and cookies

Currently, this site does not have a mechanism that asks for your consent before Google Analytics is used on the Japanese pages. If you do not want cookies to be stored, you can restrict them or delete stored cookies in your browser settings. For how Google Analytics measurement changes when you change your browser settings, see Google's explanation.

Advertising

This site does not currently show advertising. In preparation for using Google AdSense, a verification tag (a meta tag) has been placed in the pages to confirm ownership of the site. The tag itself does not display ads and does not make your browser load an external program.

Communication with external services

When you view a Japanese page, your browser communicates with a service provided by Google LLC (Google Analytics). In this communication, information needed for the communication, such as your IP address, reaches the server on the other end. When you view an English page, the page does not load programs from external services. If you follow a link from this site to another website, how that website handles information is governed by its own policy.

Changes to this policy

This policy may be revised when necessary.
