Last updated: 17 June 2026

This Privacy Policy explains what information NazoKai ("we", "us") collects when you visit nazokai.com (the "Site"), how we use it, and the choices you have. By using the Site, you agree to this policy.

Information we collect

You can use NazoKai without creating an account or giving us your name. We collect:

  • Usage data — pages you view, the time and date, referring page, and general interaction with the Site.
  • Device & technical data — browser type, operating system, screen size, and an approximate location derived from your IP address (we do not store your precise location).
  • Cookies and similar technologies — small files used to remember preferences and to support analytics and advertising (see below).

Cookies

Cookies help the Site remember your preferences and let us and our partners understand how the Site is used. You can control or delete cookies through your browser settings. Blocking some cookies may affect how parts of the Site work.

Advertising

We keep NazoKai free with advertising. We may work with third-party advertising partners, including Google, to serve ads.

  • Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.
  • Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our Site and/or other sites on the Internet.
  • You can opt out of personalised advertising by visiting Google Ads Settings, or opt out of third-party vendors' use of cookies for personalised ads at aboutads.info.

Analytics

We use analytics to measure traffic and improve the Site. Analytics providers process usage and device data on our behalf and are not permitted to use it for their own purposes beyond providing the service.

How we use information

  • To operate, maintain and improve the Site and its content.
  • To understand which puzzles and pages are useful.
  • To display and measure advertising.
  • To detect, prevent and address technical issues or abuse.

Sharing

We do not sell your personal information. We share data only with service providers (such as hosting, analytics and advertising partners) who process it on our behalf, or where required by law.

Your choices

  • Manage or block cookies in your browser.
  • Opt out of personalised ads using the links above.
  • Use your browser's "Do Not Track" setting; we honour signals where technically feasible.
