Privacy Policy — PriceKampung

Last updated: 22 June 2026

PriceKampung is a browser extension that helps you judge a Shopee listing: it shows the shop's trust signals and a pooled price history so you can tell a genuine discount from a fake one. PriceKampung is an independent project and is not affiliated with, authorized by, or endorsed by Shopee. This policy explains exactly what data the extension handles, what leaves your browser, and why.

The short version

• We collect no personal data — no name, email, account, IP address, cookies, or browsing identity is stored on our servers.
• The extension reads the public product and shop information already shown on the Shopee page you are viewing, using your own browser session.
• When “Contribute prices” is on (it is on by default; you can turn it off anytime from the popup), the extension sends the product and price details listed below to our backend to build a shared, community price history. These are facts about the product, not about you.
• An optional, off-by-default affiliate button can send you to the merchant via an affiliate link if you choose to use it.

What the extension does

When you view a product on shopee.sg, PriceKampung:

1. Reads the shop ID and product/price information from the page and from Shopee's own public product API (pdp/get_pc), via your existing browser session — the same data the page shows you.
2. Displays a shop-trust tooltip (shop name, rating, joined date, badges, a red/amber/green risk score) and a price-history panel (current vs typical/low/high, real vs inflated “original” price, and the after-voucher price).
3. Reads pooled price history for that product from our backend, so you see history even on your first visit.

What is sent, and to whom

The extension communicates with two servers:

• shopee.sg — Shopee's own public API, from your browser, to read the product/shop data you are already viewing.
• Our backend, hosted on Supabase — to read pooled price history, and, only when “Contribute prices” is on, to submit the price observation for the product you are viewing.

When “Contribute prices” is on, a submitted observation contains only:

platform (shopee), shop ID, item ID, variation/model ID and name, the displayed price, the “before” price, the after-voucher price and the discount/voucher breakdown, in-stock status, the product title and image URL, the listing's price range, and a timestamp.

It contains no personal identifiers. We do not store your IP address, and there is no account or login. The data describes the product, not you. We do not sell or transfer this data to third parties, we do not use it for advertising, and we do not use it to determine creditworthiness or for lending purposes.

What is stored

• In your browser: your on/off preferences (tooltips, contribute, affiliate), and a short-lived cache of public shop/price info (session storage, cleared when you close the browser).
• On our backend: the anonymous product price observations described above, retained as part of the shared price-history database.

Affiliate links

PriceKampung is free. To help fund it, the extension can show an optional “Buy via our link” button on product pages. This is off by default. If you turn it on and click it, you are taken to the merchant through an affiliate link and we may earn a small commission at no extra cost to you. We never redirect you automatically, and we never replace an existing affiliate link.

Permissions

• storage — to remember your on/off preferences and cache public shop/price info.
• Host access to https://shopee.sg/* — so the tooltip can run there and read the public shop and price data the page shows.
• Host access to our Supabase backend — to read pooled price history and (when enabled) submit anonymous price observations.
