Privacy Policy — Fansbuy extension

Last updated: November 2, 2026

The Fansbuy browser extension adds a “Buy on Fansbuy” button and QC (quality check) photos to product pages on Taobao, Tmall, 1688, Weidian, Xianyu (Goofish) and Yupoo. This policy explains what the extension does and does not collect.

What we collect

• An anonymous installation ID. A random identifier created when the extension is installed. It is not linked to your name, email, account or any personal information.
• The invite code, if any. If you installed the extension from a promoter’s invite link, we store which invite it came from, so promoters can see how many installations they brought.
• Anonymous usage counts. At most once every 6 hours, a “still in use” signal; and a count each time you click “Buy on Fansbuy”. These contain only the installation ID — not the product, the page you were on, or anything you browse.
• Product IDs for QC photos. To show QC photos, the extension sends the platform and the numeric product ID of the product page you are viewing to our server, which looks up photos from the Fansbuy warehouse. Results are cached on your device for a few hours.

What we do not collect

• No personal information (name, email, address, phone, payment details).
• No browsing history, no page contents, no cookies from other websites, no keystrokes.
• No data is sold or shared with third parties for advertising.

Cookies on the invite page

When you open an invite link, our invite page stores a first-party cookie with the invite code for 30 days and an anonymous visitor ID, so the installation can be credited to the right promoter and visits can be counted.

Where data is stored

Data is stored on our servers (Vercel and Supabase) and kept only as long as needed to provide the extension and the invite statistics. When you uninstall the extension, the installation is marked as removed.

Your choices

You can uninstall the extension at any time from your browser’s extensions page. To ask about or remove the data linked to your installation ID, contact us at the email listed on the Chrome Web Store page of the extension.

Changes

If this policy changes, the new version will be published on this page with an updated date.
