This English version is a courtesy translation. In case of any discrepancy between the Chinese and English versions, the Chinese version shall prevail.

Important Notice

This Cookie & Local Storage Notice (the "Notice") describes the technical details, purposes, and your choices regarding cookies and browser local storage used by Welmo Technology on its website. This Notice is one of the appendices to the Privacy Policy (Document 02).

1. Overview

1.1 Our Stance

On *.welmotech.com, Welmo Technology uses only essential session cookies to maintain your login state and does not use any third-party tracking, advertising, analytics, or behavioral profiling cookies.

1.2 Key Facts

2. Cookies We Use

2.1 Field Notes

• Domain .welmotech.com: Allows the cookie to be shared across all subdomains (www.welmotech.com, spices.welmotech.com, thegreens.welmotech.com, pet.welmotech.com, admin.welmotech.com), enabling single sign-on across subdomains.
• Path /: The cookie is valid for all paths of the site.
• Secure: In production (HTTPS), cookies are transmitted only via encrypted HTTPS channels. In local development, this flag is omitted to facilitate debugging.
• SameSite=Lax: Prevents cross-site request forgery (CSRF). Requests originated from third-party sites do not automatically carry these cookies, but normal top-level navigation is unaffected.
• HttpOnly: These cookies currently do not have HttpOnly set, because the frontend JavaScript needs to read welmo_user to display login state and welmo_token to inject into the Authorization header for API requests. We recognize the XSS risk and mitigate via strict content security policies and code audits.

2.2 Consequences of Disabling

If you clear or reject the above cookies:

• You will be unable to maintain login state; you will have to log in again after refreshing;
• You will be unable to activate benefits, claim refills, view order history, or use other features that require login;
• The website's guest browsing features (homepage introduction, product showcase) are unaffected.
