The cookies we use, why we use them and how to manage them.
Last updated: 11 September 2026
This policy explains how SHENGYAN (升妍) at https://myshengyan.shop uses cookies and similar browser storage technologies such as localStorage, and how you can manage them.
1. What cookies are
Cookies are small pieces of text that a website stores in your browser. Alongside cookies we also use browser localStorage to keep your sign-in state and cart contents; both work in a similar way and are referred to together as "cookies" in this policy.

We currently use no third-party cookies for advertising or cross-site tracking.
3. Third-party services
- Payment providers: when you are redirected to the hosted authorization page of an activated payment provider, the provider may set its own essential security cookies there. Those cookies are controlled by the provider and covered by its privacy policy
- Parcel tracking: if you click through to a carrier's website to track a parcel, that site may set its own cookies
4. Managing cookies
- You can view, delete or block cookies in your browser settings, and you can browse in private/incognito mode
- If you delete or block our essential cookies you will not stay signed in, your cart may be lost, and some features will not work
- Because we do not run advertising, there is no separate "opt out of ad tracking" control
5. Changes
If we add new types of cookies (for example analytics or advertising), we will update this page, post a notice on the site and, where required, ask for your consent first.
