Privacy policy

1. Your quiz answers

Answers are kept only temporarily in the tab of your browser and are not sent to our server. They disappear when you close the tab.

When you share a result, the link contains only the displayed result and a short line, never your name or answer history.

2. Analytics

Only when a connection is identified as coming from Japan, we use Google Analytics 4 (Google LLC) to count views of public pages, using a cookie identifier, the page viewed and the type of device and browser. Answers, results and free text are not sent.

Google signals and ad personalization are turned off. Data may be processed outside Japan, for example in the United States.

3. Advertising

Only when a connection is identified as coming from Japan, ad spaces such as the one below a quiz result show non-personalized Google AdSense ads. Google and other third-party vendors may use cookies, IP addresses and device information to serve ads and prevent fraud.

Answers, results and free text are never passed to ads. See how Google uses information for advertising.

4. Usage counts

To improve the quizzes, only for connections from Japan, the site itself counts “shown”, “selected” and “completed” per language, quiz and date. The counts contain no information that identifies a person or device and no answers. Counts older than 42 days are deleted.

5. How to stop analytics and ads

With the buttons under “Privacy and settings” at the bottom of each page you can stop analytics, ads and usage counts in this browser. Browser “do not track” signals (GPC, DNT) are also respected.

6. Contact

What you send through the contact page (name, email address and message) is stored in the operator’s contact intake (a database on Cloudflare) and delivered to the operator through the email service Resend. It is used only to answer you and deleted within 12 months after receipt.

To prevent abuse, the number of sends is counted using an irreversible transformation of the connecting IP address. The IP address itself is not stored.

7. Sharing of information

Except where required by law, we do not provide information that identifies you to third parties without your consent, and we do not sell information. The services below process information on our behalf to run the site.

8. External services we use

Google LLC: Google Analytics 4 and Google AdSense (privacy policy)

Cloudflare: site delivery, usage counts and storage of contact messages (privacy policy)

Resend: email delivery of contact messages (privacy policy)

9. Access, correction and deletion

To check, correct or delete your information, please write to us through the contact page. We will respond after confirming your identity.

10. Changes and operator
