KuCoin Cookie Policy

最終更新：2026/02/11

Effective Date: January 01, 2026

This Cookie Policy explains how KuCoin and its group companies ("KuCoin", "we", "us" and "our") use cookies and similar technologies when you visit our websites located at KuCoin.com, or any other websites, pages, features, or content we own or operate (collectively, the "Site(s)"), when you use the KuCoin mobile app, and/or when you interact with KuCoin online advertisements or marketing emails (collectively the "Services"). It explains what these technologies are and why we use them, as well as your rights to control our use of them.

In some cases, we may use cookies and similar technologies to collect personal information, or information that becomes personal information if we combine it with other information. In such cases, the KuCoin Privacy Policy will apply in addition to this Cookie Policy.

If you have any questions about our use of cookies or other technologies, please submit your request via our Support Portal.

WHAT ARE COOKIES?

Cookies are small files, typically letters and numbers, downloaded onto your computer or mobile device when you visit certain websites. When you return to these websites, or visit other websites that use the same cookies, the websites recognize these cookies and your browsing device. A cookie cannot read data off your hard drive or read cookie files created by other websites.

Cookies set by the website operator are called "first party cookies". Cookies set by parties other than the website operator are called "third party cookies". The parties that set third party cookies can recognize your web browser both when it visits the KuCoin website and when it visits certain other websites where the third party’s cookies are also present.

WHY DO WE USE COOKIES?

When you access our Sites and Services, we, or companies we work with may place cookies on your computer or other devices. These technologies help us better understand user behavior and inform us about which parts of our websites people have visited.

We use first party and third-party cookies to recognize you as a KuCoin customer, customize KuCoin Services, content, and advertising, to measure promotional effectiveness, and to collect information about your computer or other access device to mitigate risk, help prevent fraud, and promote trust and safety.

We may place cookies from third-party service providers who may use information about your visits to other websites to target advertisements for products and services available from KuCoin. We do not control the types of information collected and stored by these third-party cookies. You should check the third-party's website for more information on how they use cookies.

The following are some examples of information that we collect and how we may use it:

We may collect and store details of how you use our Sites and Services. We may process IP addresses and similar identifiers in accordance with applicable law, including in anonymized or truncated form where appropriate, for purposes such as security, fraud prevention, analytics, and service improvement.

We may collect information such as your language, inferred zip code or area code, unique device identifier, referrer URL, location, and time zone so that we can better understand customer behavior and improve our Services.

We may collect information regarding customer activities on our websites and platforms, which is used to understand which parts of our Sites and Services are of most interest. This data is aggregated, and thus is considered non-personal information for the purposes of this Cookie Policy and our Global Privacy Policy.

WHAT TYPES OF COOKIES DO WE USE?

We use the following types of cookies:

Strictly Necessary Cookies

These cookies are necessary for the Sites to function and cannot be switched off in our systems. They are usually only set in response to actions made by you which amount to a request for services, such as setting your privacy preferences, logging in, or filling in forms. These also include cookies we may rely on for fraud prevention. You can set your browser to block or alert you about these cookies, but some parts of the site will not then work.

Performance/Analytics Cookies

These cookies allow us to count visits and traffic sources so we can measure and improve the performance of our Sites. They help us to know which pages are the most and least popular and see how visitors move around the site. All information these cookies collect is aggregated and therefore anonymous. If you do not allow these cookies, we will not know when you have visited our site and will not be able to monitor its performance.

Functionality Cookies

These cookies allow us to remember the choices you make and to tailor our services, so we can provide relevant content to you. For example, a functionality cookie can remember your preferences (e.g., country or language selection), or your username.

Targeting/Advertising Cookies

KuCoin uses third party service providers to display advertising on our Services and serve advertising on other third-party sites that may be relevant to you or your interests. These cookies are also used to help measure the effectiveness of the advertising campaign. They remember that you have visited a website and this information may be shared with other organizations, such as advertisers. This means that after you have been to our websites, you may see some advertisements about our Services elsewhere on the Internet. The information collected through this process by the third-party service providers does not enable us or them to identify your name, contact details or other personal information that directly identifies you unless you choose to provide these. Such advertising will only be delivered where permitted by applicable law. If you do not allow these cookies, you will experience less advertising tailored to your inferred interests on our Sites and will not receive targeted KuCoin advertisements on third party websites.

HOW LONG WILL COOKIES STAY ON MY BROWSING DEVICE?

The length of time a cookie will stay on your browsing device depends on whether it is a "persistent" or "session" cookie. Session cookies expire when you close your browser. Persistent cookies remain on your device for a defined period, which may range from a few days to several months, unless deleted earlier.

WHAT OTHER SIMILAR TECHNOLOGIES DOES KUCOIN USE?

In addition to cookies, we may use other similar technologies, like web beacons to track users of our Sites and Services. Web beacons, or "clear gifs," are tiny graphics with a unique identifier, similar in function to cookies. They are used to track the online movements of web users.

In contrast to cookies, which are stored on a user's computer hard drive or device, clear gifs are embedded invisibly on web pages and are about the size of the period at the end of this sentence. We and our third-party service provider employ web beacons for the reasons stated above (under "Cookies"), but primarily to help us better manage content on our Services by informing us which content is effective.

We may also use so-called "Flash Cookies" (also known as "Local Shared Objects or "LSOs") to collect and store information about your use of our services, fraud prevention and for other site operations.

COOKIE CONSENT MANAGEMENT

Where required by applicable law, when you first visit our Sites, you will be presented with a cookie notice or consent banner that allows you to accept or reject certain categories of cookies. You may change your preferences at any time through our “Cookie Settings” tool (if available) or by adjusting your browser settings.

Your consent applies only to the specific device and browser you are using at the time you provide it.

HOW TO MANAGE COOKIES, SIMILAR TECHNOLOGIES, AND TARGETED ONLINE MOBILE ADVERTISING

You have the right to decide whether to accept cookies. You can exercise your preferences in relation to cookies served on our Sites by taking the steps outlined below.

Cookies. You can enable or disable categories of cookies. This includes both first party and third-party cookies. You can also use the browser with which you are viewing this website to enable, disable or delete cookies. To do this, follow the instructions provided by your browser (usually located within the "Help", "Tools" or "Edit" settings), or review the instructions provided by the browsers listed here: Internet Explorer, Google Chrome, Mozilla Firefox, Safari Desktop, Safari Mobile, and Android browser. Please note, if you set your browser to disable cookies, you may not be able to access secure areas of the Sites and Services. Also, if you disable cookies, other parts of the services may not work properly.

Mobile Advertising: You can opt out of having your mobile advertising identifiers used for certain types of advertising by accessing the appropriate settings in your mobile device and following the instructions. If you opt-out, we will cease using your mobile advertising identifiers for targeted advertising purposes. However, we may continue to process certain information as required for security, fraud prevention, legal compliance, or other legitimate operational purposes. If at a later stage, you decide to opt-in, we will be unable to continue and track you and you will, for all practical purposes, be a new user.

Do Not Track: Some Internet browsers - like Internet Explorer, Firefox, and Safari - include the ability to transmit "Do Not Track" or "DNT" signals. Since uniform standards for "DNT" signals have not been adopted, our Sites do not currently process or respond to "DNT" signals.

Information collected through cookies and similar technologies may be transferred to and processed in countries outside your country of residence, including jurisdictions that may not provide the same level of data protection. Where required by applicable law, we implement appropriate safeguards for such transfers in accordance with our Privacy Policy.

YOUR RIGHTS

Subject to applicable law, you may have the right to access, correct, delete, restrict, or object to certain processing of your personal information collected through cookies and similar technologies. You may also have the right to withdraw your consent at any time where processing is based on consent.

For further details on how to exercise your rights, please refer to our Privacy Policy.

WILL THIS COOKIE POLICY BE UPDATED?

We may update this Cookie Policy from time to time to reflect, for example, changes to the cookies we use or for other operational, legal or regulatory reasons. If we do, you will be notified when you first visit our website after the change. You can also revisit this page if you wish to keep yourself informed.
