We will take all steps reasonably necessary to ensure that your personal information is stored and processed securely and in accordance with this Privacy Policy and applicable laws.

To help us make e-mails more useful and interesting, we often receive a confirmation when you open e-mail from our e-shopping website if your device supports such capabilities. We also compare our customer list to lists received from other companies, in an effort to avoid sending unnecessary messages to our customers.

We collect information from other sources. We might receive information about you from other sources, which are duly authorized by yourself to transfer such information to third parties and add it to our account information.


How we use your personal information

  • The personal information we collect allows us to keep you posted on our latest product announcements, software updates, and upcoming events. If you don’t want to be on our mailing list, you can opt out anytime by updating your preferences.
  • We also use your personal information to help us create, develop, operate, deliver, and improve our products, services, content, and advertising to improve your user experience continually.
  • We may use your personal information to respond to your inquiries and fulfill your requests.
  • We may use your personal information, including date of birth, to verify identity, assist with identification of users, and to determine appropriate services. For example, we may use date of birth to determine the age of user account holders.

Cookies and Other Technologies

Our websites, online services, interactive applications, email messages, and advertisements may use “cookies” and other technologies. These technologies help us better understand user behavior, tell us which parts of our websites people have visited, and facilitate and measure the effectiveness of advertisements and web searches. We treat information collected by cookies and other technologies as non-personal information. However, to the extent that IP addresses or similar identifiers are considered personal information by local law, we also treat these identifiers as personal information. Similarly, to the extent that non-personal information is combined with personal information, we treat the combined information as personal information for the purposes of this Privacy Policy.

Kai and our partners also use cookies and other technologies to remember personal information when you use our website, online services, and applications.

You may configure your browser to accept all cookies, reject all cookies, or notify you when a cookie is sent. Each browser is different, so check the “Help” menu of your browser to learn how to change your cookie preferences.

In some of our email messages, we use a “click-through URL” linked to content on our website. When customers click one of these URLs, they pass through a separate web server before arriving at the destination page on our website. We track this click-through data to help us determine interest in particular topics and measure the effectiveness of our customer communications. If you prefer not to be tracked in this way, you should not click text or graphic links in the email messages.
