PriceMinder Privacy Policy

Shopee Price Sentinel · Last updated: October 15, 2026

Overview

PriceMinder (hereinafter "this extension") is a Chrome browser extension designed for Shopee cross-border sellers, providing competitor price monitoring and alert notifications. We value your privacy. This policy explains what data we collect, how we use it, and how we protect your information.

Data We Collect

This extension only collects the following data when you actively initiate an action:

  • Product information — When you click "Add to Watch" on a Shopee product page, the extension reads the current page's product name, price, product link, and store name
  • Price records — The backend collection engine periodically scrapes prices for products you've added to monitoring, building price history data
  • Extension settings — Your alert thresholds, polling intervals, and other preference settings
  • Website statistics (optional, consent-based) — When you accept analytics cookies, Google Analytics 4 and Baidu Tongji record anonymous visit data (pages viewed, referral source, country, device type). IP addresses are anonymized. These cookies are only set after you opt in via the consent banner; declining leaves statistics fully off.
  • Email subscription (optional) — If you subscribe to the weekly brief, we store your email address, the subscription time, the page you subscribed from, and your IP address. This record exists to prove consent (double opt-in) and to honor unsubscribes. We never sell or share it with third parties for marketing.
This extension does not automatically collect any data. All data collection is either actively triggered by you (adding a watch) or executed by a backend scheduled task you've authorized (price collection).

Data We Do NOT Collect

  • Your browser browsing history
  • Your Shopee account, password, or login credentials
  • Your personal identifying information (name, email, phone number, etc.)
  • Any page content unrelated to monitored products

How Data Is Stored

All monitoring data (product info, price records, alert records) is stored in a cloud PostgreSQL database deployed on servers in mainland China. Data is transmitted via HTTPS encryption, and the database has access controls and regular backups.

Your extension settings (API address, Token) are stored in Chrome's local storage (chrome.storage) and are never uploaded to third-party servers.

How Data Is Used

We do not sell, share, or use your data for advertising purposes.

  • Providing price monitoring and change alert services
  • Generating price trend charts and historical records
  • Pushing price-drop alerts via Feishu (Lark) Webhook or desktop notifications
  • Providing price data query capabilities to AI assistants via the MCP protocol

Cookies & Local Storage

The extension saves its configuration in your browser's local storage (chrome.storage) and never uploads it to third-party servers.

The website priceminder.online uses local storage to remember interface preferences (language, theme, and your privacy choices). For statistics we use Google Analytics 4 (with IP anonymization and Consent Mode v2) and Baidu Tongji. Both stay fully disabled until you opt in through the consent banner — before that, no analytics cookies are written. You can change your choice at any time by clearing site data; the banner will reappear.

The weekly-brief confirmation email contains a one-click unsubscribe link. Every sent issue also carries one. Unsubscribing takes effect immediately.

Data Retention

Monitoring data is deleted when you remove the corresponding monitor or close your account; server logs are kept for no more than 90 days and used only for troubleshooting and security auditing. Transaction and billing records are retained for the period required by applicable law.

Permissions Explained

This extension requests the following Chrome permissions for these purposes:

  • storage — Saves your API address, Token, monitored product list, and alert settings to browser local storage (chrome.storage.local)
  • notifications — Pushes desktop alert notifications via Chrome when a competitor drops their price
  • alarms — Uses Chrome scheduled tasks (chrome.alarms) to periodically check for price changes and trigger alert detection
  • host_permissions (shopee.sg / .com.my / .co.th / .vn / .com) — Injects the "Add to Watch" button on Shopee product pages and reads product name, price, and other data
  • host_permissions (priceminder.online) — Communicates with the backend service to sync monitoring data and push alerts
This extension does not request highly sensitive permissions such as activeTab, tabs, scripting, or cookies. All data collection is either actively triggered by you (clicking "Add to Watch") or executed by a backend scheduled task you've authorized (price detection).

How to Delete Your Data

You can delete your data at any time through the following methods:

  • Delete monitored products individually in the extension popup panel
  • Click "Clear All Data" on the extension settings page
  • After uninstalling the extension, locally stored configuration is automatically cleared by the browser

To permanently delete cloud data, please contact us using the information below. We will process your request within 7 business days.

Policy Updates

This privacy policy may be updated as product features evolve. Updated policies will be published on this page with a revised date. Significant changes will be communicated to users via in-extension notifications.
