China Buy Agent ("the extension", "we") is a browser extension that helps you shop on Xianyu (goofish.com), 1688.com, Alibaba.com, Taobao and Tmall through shopping agents such as Superbuy and SugarGoo. It is built by Gloqqa.
Stored only in your browser, using the browser's extension storage: - Settings: language, currency, default shopping agent, "Superbuy links" mode, and the on/off switches for each feature. - Save for Later: the items you save (page address, title and main image address), your groups, and their order. - Caches: exchange rates (and the time they were fetched) and translations of search terms you have used. - Search helper data: the last search term you typed (so "Advanced Search" can reuse it), and, for up to 10 minutes after you click "Advanced Search", the prompt prepared for DeepSeek. - Small flags: that you accepted the terms, that the Alibaba welcome message has been shown, and that you have used the Warehouse button. - Superbuy sign-in flag: a single yes/no value and the time it was last checked (see "Superbuy sign-in detection"). - A pending purchase: after you click a Buy link, the product page address is kept for up to 30 minutes (see below).
Settings use the browser's sync storage, so if you are signed in to Chrome or Firefox Sync your browser may sync them between your own devices, under the browser vendor's privacy policy. Nothing else is synced.
| When | Where | What is sent |
|---|---|---|
| About once a day, in the background | api.exchangerate-api.com |
A request for CNY exchange rates. No personal data. |
| You use the translated search box on Xianyu, 1688, Taobao or Tmall | translate.googleapis.com (Google Translate) |
The search text you typed, to translate it into Chinese. Google's privacy policy applies to it. |
| You click "Advanced Search" | Your clipboard, then chat.deepseek.com |
See "Advanced Search and DeepSeek" below. |
The Buy and Save buttons, the Alibaba welcome message and the Superbuy sign-in check make no network requests of their own.
When you click Advanced Search, the extension copies a ready-made prompt, which includes the search term you typed, to your clipboard and opens DeepSeek (chat.deepseek.com) in a new tab. It also keeps the prompt in local storage for up to 10 minutes so it can show a "Paste into search box" button on DeepSeek. Nothing is sent to DeepSeek unless you press send yourself. The extension only fills the empty message box; it does not read your DeepSeek conversations or account. What you submit on DeepSeek is handled under DeepSeek's own terms and privacy policy. The extension does not use clipboard-read access.
On superbuy.com the extension checks whether the page is showing "Sign in / Sign up" buttons and saves one yes/no flag (and the time) on your device. While the flag says you are signed in, Buy links go straight to Superbuy's buy page without the developer's affiliate code, so you are not sent back to the login page. The flag is cleared if you sign out, and forgotten after 60 days without being seen.
When you click a Buy link, the product page address is kept on your device for up to 30 minutes, so that if Superbuy asks you to sign in or register, the extension can take you to that product afterwards. It is deleted as soon as it is used or expires, and it is never sent anywhere other than to Superbuy as part of the link you clicked.
If you are not signed in, the extension may reload a Superbuy sign-in, sign-up or buy page once with the developer's affiliate code added to its web address, so a sign-up you make there is credited. This only happens on Superbuy pages you reached by clicking a Buy link from the extension. You can change this in Settings → Superbuy links (Auto, Always direct, or Always use the sign-up link).
Buy buttons, the Warehouse button and some sign-up links lead to Superbuy and SugarGoo. These are affiliate links: if you register or buy through them, the extension's developer may earn a commission at no extra cost to you. When you click, the product page address is passed to the agent in the link. The agents' handling of your data is governed by their own privacy policies. We are not affiliated with, endorsed by, or connected to Superbuy, SugarGoo, Xianyu, 1688.com, Alibaba, Taobao, Tmall, Google or DeepSeek.
