Cookie Policy
This policy explains how the personal-data controller, Shanghai Liangpin Testing Technology Service Co., Ltd (operating the Greenbrain.store platform; registered in Shanghai, hereinafter “we”), uses cookies and similar technologies when you visit the GreenBrain platform, including their types, purposes and how to manage them.
1. What Are Cookies
Cookies are small text files a website stores on your device to remember your actions and preferences (such as sign-in status and language) so you do not have to re-enter them each time. Some cookies are essential for the site to work; others improve your experience. Besides cookies, the platform also uses browser session storage (sessionStorage) to carry a temporary first-party usage-statistics identifier.
2. Necessary Cookies
These cookies are the basis on which the site runs, used for sign-in, session management and security. Example: the sign-in session cookie (named sb-<project-id>-auth-token, split into chunks such as .0 and .1 when the session is large), written by the session service, with Path=/ and SameSite=Lax, Secure enabled in production, lasting up to 400 days; clearing it requires signing in again.
3. Preference Cookies
These cookies remember your preferences. Example: NEXT_LOCALE, which remembers the Chinese or English choice for 1 year and can be cleared at any time; once cleared, the platform negotiates automatically from the browser language.
4. Analytics
The platform does not use third-party analytics cookies. Usage statistics are performed through a temporary session identifier in browser session storage (expiring when the tab closes) and server-side records: the server records page path, interface language, device type and key actions, linking signed-in users to account and company identifiers while anonymous visits keep only the session identifier; IP addresses are not recorded. These records are retained for 90 days by default and pruned periodically.
5. Marketing Cookies
The platform currently uses no advertising, marketing or cross-site tracking cookies. This category is listed only for transparency.
6. How to Manage Cookies
You can view, clear or block this storage in your browser settings. Note that blocking the sign-in session cookie will prevent you from signing in, and blocking or clearing the language-preference cookie will stop the platform remembering your language choice.
7. Third-Party Cookies
No third-party advertising or analytics service currently sets cookies on this platform. The hosting and authentication services the platform uses serve the service itself and are not used for on-site advertising tracking.
8. Your Rights
You may withdraw consent for non-essential storage at any time and delete stored cookies in your browser. If your jurisdiction grants relevant rights (such as within the scope of the California Consumer Privacy Act and its amendments), you may exercise them through the channel below.
9. Changes to This Policy
We may update this Cookie Policy from time to time; significant changes take effect once published on this page.
