Privacy Policy for Children

The basic principles of this Privacy Policy are safety, security, and appropriate use of your personal information. Parents, please read through this policy and note your role in ensuring a positive and safe experience for your child.

We have adopted this Privacy Policy to protect the privacy of our customers including our youngest puzzle lovers- especially for children under the age of 13. We believe that the best way to protect children is to give parents the means to control what information is collected from their children, how it is used, and with whom it is shared.

This Privacy Policy describes what personal information we collect from children who are authorized users of this Site or our services and how we use and share that information. It also describes the choices parents have about the ways we collect, use, and share their children's information.

We take reasonable precautions to protect the confidentiality and security of the information we maintain about your child. It is important that you understand, however, that no Web site or database is completely secure or "hacker proof."

- Password Protection: For your child's protection, all authorized users must log in each time they visit the Site. Nikoli will send your child an email containing a password as soon as your child's registration is complete. Please make sure your child does not share his or her password with others. We have the right to assume that anyone who accesses this Site using your child's password is, in fact, your child and we will grant access accordingly.

- Information Sent to Us by Your Child's Web Browser: We collect information that is sent to us automatically by the child's web browser. This information typically includes the child's computer's IP address, the address of the web page the child was visiting when he or she accessed our Site, the name of the operating system (such as Windows? or Macintosh?) installed on the child's computer, the name and version of the browser (such as Netscape? or Internet Explorer?) the child is using, and the date and time of the child's visit. The information we receive depends on the settings on the child's web browser. Please check your child's browser if you want to learn what information the browser sends or how to change your settings.

We require a child under the age of 13, who use the Site, to obtain written consent from a parent or guardian before registering the Site. Click here to download consent forms. A parent who has given his or her consent may withdraw it at any time by contacting our Customer Service area by sending a dated and signed request that includes your child's name and email address by mail or by fax to: Nikoli Co., Ltd. Nihonbashi-hamacho Bldg.3F, 3-36-5 Nihonbashi-hamacho, Chuo-ku, Tokyo 103-0007, Japan,

We believe that you, as a parent, have the right to know the specific types or categories of personal information we have collected from your child, to review the information your child has provided, and to request that your child's personal information be deleted. Contact us directly if you would like to access your child's personal information or have it deleted. Contact Us
