Cookie Notice

 

Last Updated: October 24, 2025

 

This Cookie Notice explains how HONG KONG UGREEN LIMITED ("we," "us," or "our") use cookies and similar tracking technologies when you visit our website, https://nas-eu.ugreen.com/ (the "Site"). It explains what these technologies are and why we use them, as well as your rights to control our use of them.

This notice should be read in conjunction with our main Privacy Notice, which provides more detailed information about our data processing practices.

 

1. What Are Cookies and Other Tracking Technologies?

To provide you with a seamless and personalized experience, our Site uses various tracking technologies. Here’s a breakdown of what they are and how they work.

Cookies

Cookies are small text files placed on your computer, tablet, mobile phone, or other device ("Device") when you visit a website. They are widely used to make websites work, or work more efficiently, as well as to provide information to the owners of the site. Cookies make your browsing experience better by allowing the website to remember your actions and preferences (such as login and region selection).  

Cookies can be categorized in several ways:

· First-Party vs. Third-Party Cookies:

o First-Party Cookies are set directly by the website you are visiting (i.e., by us).  

o Third-Party Cookies are set by a domain other than the one you are visiting. These are typically set by our partners, such as advertising networks or analytics providers.  

· Session vs. Persistent Cookies:

o Session Cookies are temporary and expire once you close your browser.  

o Persistent Cookies remain on your Device for a set period specified in the cookie, or until you manually delete them.  

 

Other Tracking Technologies

In addition to cookies, we use other similar technologies. It is important to understand these, as they work alongside cookies to help us understand user activity and improve our services.

· Tracking Pixels (also known as Web Beacons or Clear GIFs): A tracking pixel is a tiny, invisible 1x1 graphic embedded in a web page, email, or advertisement. When your browser loads a page or email containing a pixel, it sends specific information directly back to a server, such as your IP address, browser type, and your interaction with the content. Unlike cookies, which are stored on your device, pixels are not easily disabled by the end-user.  

 

2. How and Why We Use These Technologies

We use first-party and third-party technologies for several reasons. Some are required for technical reasons for our Site to operate, while others enable us to track and target the interests of our users to enhance their experience. Third parties serve cookies and other technologies through our Site for advertising, analytics, and other purposes.

The specific types of technologies used on our Site are described below:

a. Strictly Necessary Cookies

These cookies are essential to provide you with services available through our Site and to use some of its features, such as accessing secure areas or using the shopping cart. Because these cookies are strictly necessary to deliver the Site to you, they are activated without your consent, but we are still transparent about their use. Without these, the services you have asked for cannot be provided, and our Site may not function as expected.  

b. Performance Cookies (also known as Analytics Cookies)

These cookies collect information that is used in aggregate form to help us understand how our Site is being used or how effective our marketing campaigns are. They allow us to count visits and traffic sources so we can measure and improve the performance of our Site. This data helps us identify which pages are popular, troubleshoot performance issues, and ultimately improve your experience.  

 

c. Functional Cookies

These cookies are used to enhance the functionality of our Site but are non-essential to its use. They are used to remember choices you make (such as your user name, language, or the region you are in) and provide enhanced, more personal features. For example, these cookies can be used to remember your localization preferences. If you do not allow these cookies, some of these services may not function properly.  

d. Targeting Cookies (also known as Advertising Cookies)

These cookies are set through our site by our advertising partners to provide behavioral advertising and re-marketing analytical data. They may be used by those companies to build a profile of your interests and show you relevant advertisements on other sites. They work by uniquely identifying your browser and Device. These cookies track your browsing activity across websites to create a detailed interest profile, which is then used for personalized advertising. If you do not allow these cookies, you will experience less targeted advertising.  

 

3. Your Choices and How to Manage Cookies

We respect your right to privacy and provide you with tools to manage your preferences. With the exception of Strictly Necessary cookies, we will only place cookies on your Device with your explicit consent.

Our Cookie Consent Tool: You can exercise your cookie preferences at any time by clicking on the "Cookie Settings" link in the footer of our website. Our consent tool allows you to see a detailed list of every cookie we use and to select which categories of cookies you accept or reject. You can withdraw your consent at any time with the same ease with which it was given.  

Browser Controls: Most web browsers allow you to control cookies through their settings. You can set or amend your web browser controls to accept or refuse cookies. If you choose to reject cookies, you may still use our Site, though your access to some functionality and areas may be restricted. As the means by which you can refuse cookies vary from browser to browser, you should visit your browser's help menu for more information.
