Privacy Policy

1. Overview

Cosmonian (the Site) respects your privacy. This policy explains what information the Site handles, how, and what choices you have. It applies to the English pages under /en/ as well as the Japanese pages.

2. Your birthday

The 12 Star People test asks for your birthday (month, day, year). The calculation runs entirely inside your browser. Your birthday is not sent to our servers or to anyone else.

To remember your result and reuse it on other pages of the Site, the birthday you entered is saved in your browser's local storage on your own device. It stays there until you delete it. Clearing this Site's data in your browser settings removes it; after that, you will simply be asked to enter it again.

We do not ask for your name, email address, or any other personal details to use the test.

3. Analytics

To understand how the Site is used and to improve it, we use Microsoft Clarity, an analytics service. It uses cookies and similar technologies to collect information such as pages viewed, device type, and interactions on the page. This information does not identify you by name. Form fields where you enter your birthday are masked and are not recorded.

You can decline analytics cookies by disabling cookies for this Site in your browser. Microsoft's own privacy statement describes how Clarity handles data.

4. Advertising

The Site may display advertisements served by third-party providers. These providers may use cookies to show ads based on your interests. You can opt out of interest-based advertising through each provider's settings page or through your browser's cookie settings.

5. Affiliate links

Some pages may contain affiliate links to third-party products or services. If you click one of these links and make a purchase or sign up, the Site may receive a commission at no extra cost to you. Affiliate links are labeled as such on the page where they appear.

The Japanese pages of the Site participate in the Amazon Associates Program (Amazon.co.jp) and other Japanese affiliate networks. The English pages may link to services such as online personal readings. These programs may set cookies to track referrals. You can disable cookies in your browser settings.

6. Sharing buttons and external links

Share buttons open X (Twitter), WhatsApp, or LINE in a new tab. Nothing is posted unless you confirm it on that service. The Site contains links to external websites; we are not responsible for their privacy practices.

7. Children

The Site is intended for general audiences and does not knowingly collect personal information from children. Because no personal information is required to use the test, none is collected from anyone.

8. Your rights

Because your birthday is stored only on your own device, you control it directly: delete the Site's data in your browser to erase it. For questions about analytics data or anything else in this policy, contact us using the details below.

9. Changes to this policy

We may update this policy when necessary. Changes will be posted on this page with a new date at the top.

10. Contact

Questions about this policy can be sent to us on X (Twitter): @cosmonian_star. We read English and Japanese.
