II. What Are Cookies and Similar Technologies

2.1 Definition of Cookies

A cookie is a small text file sent by a website’s server and stored in the browser of your terminal equipment (including computers, smartphones, and tablets). When you visit the same website again, the browser automatically transmits the cookie back to the server, enabling the website to recognize your device, remember your session state and preference settings, and thereby provide a more coherent and personalized browsing experience.

2.2 Similar Technologies

In addition to cookies, this Website may employ the following similar technologies: web beacons (also known as pixel tags), local storage (Local Storage and Session Storage), ETag cache identifiers, and embedded scripts. These technologies resemble cookies in function and mechanism; accordingly, this Policy uses the term “cookies” to encompass all such technologies, unless the context otherwise requires.

2.3 Relationship Between Cookies and Personal Information

A cookie does not, in itself, directly contain explicit personal-identity information such as your name or email address; however, device identifiers, session tokens, and preference data stored in cookies may, when combined with other information that you actively provide, constitute personal information within the meaning of PIPL. Accordingly, our processing of data collected through cookies is subject to the corresponding protective rules set out in the Personal Information Protection Policy published on this Website.

III. Classification of Cookies

3.1 Essential Cookies

Essential cookies are strictly necessary for the basic functioning of this Website, including maintaining session state, distinguishing human traffic from automated bots, ensuring website security, and enabling language and region switching. These cookies cannot be disabled through this Website’s preference settings; if you forcibly disable them through your browser, some or all functions of this Website may cease to operate correctly.

3.2 Preference Cookies

Preference cookies are used to remember the options you have set on this Website, such as theme mode (dark or light), language preference, font size, and temporary form contents. These cookies materially enhance the continuity of your experience on return visits, but disabling them does not affect the availability of the core functions of this Website.

3.3 Analytics Cookies

Analytics cookies are used to collect and compile anonymous access data about this Website, including page-views, unique visitors, time on page, traffic sources, and bounce rates. We rely on this data to evaluate content quality, identify performance bottlenecks, and continuously optimize the structure and user experience of the Website. The information collected by these cookies is de-identified and is not directly linked to the personal information that you actively provide.

3.4 Marketing Cookies

As a matter of principle, this Website does not deploy marketing cookies for cross-site tracking or targeted advertising. Should we introduce such functionality in the future, we will obtain your explicit consent in advance and disclose it separately in this Policy and in the cookie preference banner.

IV. Specific Cookies We Use

4.1 First-Party Cookies

The first-party cookies deployed on this Website are set and managed directly by SIMDA and primarily include: a session identifier cookie (name: simda_session; purpose: to maintain login and session state; type: essential; retention: session, expires when the browser is closed); a preference-storage cookie (name: simda_prefs; purpose: to remember user preferences such as theme and language; type: preference; retention: 365 days); a consent-record cookie (name: simda_consent; purpose: to record your consent choice regarding this Policy and the cookie banner; type: essential; retention: 180 days); and a security-protection cookie (name: simda_csrf; purpose: to guard against cross-site request forgery attacks; type: essential; retention: session).

4.2 Analytics Cookies and Third-Party Services

This Website may deploy analytics cookies set by third-party analytics services that we have carefully evaluated. These cookies are set and managed by the relevant third-party service providers and are used to provide us with anonymous reports on Website traffic. They include: a visitor-analytics cookie (name: _ga; purpose: to distinguish unique visitors; retention: 24 months); a session-analytics cookie (name: _gid; purpose: to distinguish separate sessions; retention: 24 hours); and a traffic-source cookie (name: _utmz; purpose: to record referral-source information; retention: 6 months). The providers of these third-party analytics services bear independent data-protection responsibility for the cookies they set, and their processing activities are governed by their own privacy policies.

When this Website introduces new cookies or makes material adjustments to the purpose or retention period of existing ones, we will promptly update this Policy, either in the supplementary provisions or on a dedicated cookie-list page, and bring the change to your attention by conspicuous means as required by law.

V. Third-Party Cookies

5.1 Sources of Third-Party Cookies

Certain functions of this Website (such as embedded maps, video playback, font services, and traffic analytics) depend on third-party service providers. When you use these functions, the relevant third parties may set cookies on your terminal equipment through this Website, in order to deliver their services or to conduct their own statistical analysis.

5.2 Independent Responsibility of Third Parties

The processing purpose, method, and security measures for cookies set by third parties through this Website are determined by, and are the responsibility of, the third party concerned. We recommend that, before using the relevant functions, you review the cookie policy and privacy terms published by that third party in order to understand its specific data-processing rules. We do not bear direct responsibility for the processing of third-party cookies, but we undertake to carefully evaluate the compliance status of our partners when selecting them.

5.3 Principal Third Parties Evaluated

The principal third-party services currently involved on this Website comprise website-traffic analytics services, map services, and font services. We have entered into data-processing agreements or service agreements with the foregoing service providers that clearly set out their data-security obligations, and require them to minimize the processing of your information within the scope permitted by law.

VI. Managing and Controlling Cookies

When you visit this Website for the first time, a cookie preference banner will appear at the bottom of the page, explaining the types of cookies we use and providing selection buttons. Through this banner you may choose “Accept All”, “Accept Only Essential Cookies”, or “Customize Preferences”. Your selection will be recorded in the consent-record cookie and will remain in effect for its retention period.

6.2 Management via Browser Settings

Most modern browsers support granular management of cookies. You may view, enable, disable, or delete stored cookies from your browser’s “Settings” or “Privacy” menu. For your convenience, the cookie-management entry points for mainstream browsers are listed below: Google Chrome (Settings, Privacy and security, Third-party cookies); Mozilla Firefox (Settings, Privacy & Security, Cookies and Site Data); Microsoft Edge (Settings, Cookies and site permissions); and Apple Safari (Preferences, Privacy, Cookies and website data). If you use another browser, please consult its official help documentation.

You may at any time delete stored cookies through your browser settings or reset your selection through the cookie preference banner on this Website; doing so constitutes the withdrawal of your consent to the corresponding cookie-processing activities. Withdrawal of consent does not affect the validity of processing activities, based on that consent, that were carried out before the withdrawal. Withdrawing cookies other than essential cookies will not affect the availability of the core functions of this Website.

6.4 Impact of Disabling Cookies

If you choose to disable essential cookies, certain functions of this Website (such as session persistence, form submission, and security verification) may not operate correctly, and you may not be able to make full use of the services offered by this Website. Disabling preference and analytics cookies does not affect the core functions of this Website, but may reduce the continuity of your browsing experience and prevent us from obtaining the key anonymous data used to improve the Website.

VII. Relationship Between Cookies and Personal Information Protection

7.1 Coordinated Application

This Policy is applied in coordination with the Personal Information Protection Policy published on this Website. For data collected through cookies that constitutes personal information, we will, in accordance with the Personal Information Protection Policy, provide channels through which you may exercise your rights of access, correction, deletion, withdrawal of consent, and complaint, and we will apply protective measures of the same standard, including encryption, masking, and tiered authorization.

7.2 Data Security

With reference to the national cybersecurity classified-protection system, we apply technical and organizational measures to data collected through cookies, including encryption in transit, masked storage, and access auditing, in order to prevent data leakage, tampering, loss, or unauthorized access. In the event of a security incident involving cookie data, we will respond in accordance with the contingency mechanism set out in Section 5.4 of the Personal Information Protection Policy, dispose of the incident in a timely manner, and notify you as required by law.

7.3 Cross-Border Processing

As a matter of principle, information collected through cookies is stored on servers located within the People’s Republic of China. Where the technical architecture of a third-party service provider genuinely requires the transfer of such data outside the People’s Republic of China, we will, in strict accordance with Articles 38 through 40 of PIPL, do so by means of a security assessment, professional certification, or a standard contract, and take the necessary measures to ensure that the overseas processing activities meet the standard of protection required by the law.

VIII. Protection of Minors

If you are a minor, please use this Website and configure your browser’s cookie preferences under the supervision of a guardian. A guardian may contact us at any time through the channels set out in Section X of this Policy and request that we delete information about a minor collected through cookies.

IX. Updates to This Policy

We may, from time to time, revise this Policy owing to business adjustments, technological upgrades, or changes in laws and regulations. For material changes involving the addition of cookie types, the change of third-party service providers, or the adjustment of cross-border data-processing methods, we will alert you by means of a pop-up window, an announcement, or the cookie preference banner, displayed prominently on this Website, and, where necessary by law, will obtain your consent anew. If you do not agree with the revised content, you may disable the relevant cookies through your browser or cease using the corresponding functions of this Website.
