PriceSpy Privacy Policy

Last updated: September 20, 2026

    TL;DR: PriceSpy stores all your data locally in your browser. We collect no data, run no analytics, and have no backend server. Your tracked products, price history, and preferences never leave your device.
  

1. Information We Collect

We do not collect any information. PriceSpy does not have a backend server. No user data — including tracked products, price history, preferences, or personal information — is transmitted to or stored on any external server.

2. Data Stored Locally

The following data is stored on your device using your browser's local storage mechanisms (chrome.storage.local and localStorage):

Tracked products — Product names, URLs, prices, and images you choose to track
Price history — Historical price data for products you've tracked
Preferences — Your target prices, notification settings, and display preferences

This data remains entirely on your device. Clearing your browser data will remove it.

3. Network Requests

PriceSpy makes network requests only to:

E-commerce product pages (Amazon, eBay, Walmart, Taobao, JD.com, etc.) — to read current product prices directly from the page you're visiting

No data is sent to any third-party server. No analytics, tracking pixels, or telemetry of any kind are used.

activeTab — Access the current tab only when you click the extension icon to start tracking a product
