Privacy Policy for Honest Price Tracker
Last Updated: March 17, 2026
Effective Date: March 17, 2026
Our Core Commitment
Honest Price Tracker is built on one simple principle: Your data belongs to you.
Unlike other price tracking extensions (like Honey), we:
- ✅ NEVER modify your cookies
- ✅ NEVER upload your browsing data
- ✅ NEVER sell your information to third parties
- ✅ Process everything locally on YOUR device
This isn’t marketing speak. This is how our extension is fundamentally architected.
What Data We Collect
Data Stored Locally on Your Device
The following data is stored exclusively on your device using Chrome’s local storage:
- Tracked Product Information
- Product URLs you choose to track
- Product titles
- Current and historical prices
- Product images (URLs only)
- Timestamp of when you added the product
- Price History
- Historical price data for tracked products
- Stored in your browser’s IndexedDB
- Limited to last 100 price points per product
- Your Settings
- Price check frequency
- Notification preferences
- Custom alert thresholds
Data We Do NOT Collect
We explicitly do not collect:
- ❌ Your browsing history
- ❌ Personal information (name, email, address)
- ❌ Payment information
- ❌ Cookies or session data
- ❌ Analytics or usage statistics
- ❌ Any data from websites you visit
How We Use Your Data
Short answer: We don’t “use” your data because we never have access to it.
All data processing happens locally on your device:
-
Price Extraction: When you visit Amazon, eBay, or Walmart, our extension reads the product page in your browser to extract price information. This happens entirely on your device.
-
Price Monitoring: Our background service worker checks tracked product pages from your browser at intervals you set. No data is sent to any server.
-
Notifications: When prices drop, we use Chrome’s notification API to alert you. No external service is involved.
Data Storage Location
All data is stored in Chrome’s built-in storage mechanisms:
- chrome.storage.local: For tracked products and settings
- IndexedDB (future): For price history
- No external servers: We don’t operate any servers to store your data
You can verify this yourself:
- Open Chrome DevTools (F12)
- Go to Application → Storage
- Check IndexedDB and Local Storage
- You’ll see all your data stored locally
Data Sharing
We never share your data because we never have access to it.
Specifically:
- ❌ No third-party analytics (no Google Analytics, no Mixpanel)
- ❌ No advertising networks
- ❌ No data brokers
- ❌ No “anonymized” data sharing
- ❌ No cookies modified or tracked
How We’re Different from Competitors
Honey (PayPal)
- ❌ Modifies cookies to hijack affiliate links
- ❌ Uploads browsing data to their servers
- ❌ Shares data with PayPal and partners
Honest Price Tracker:
- ✅ Never touches cookies
- ✅ Zero data upload
- ✅ 100% local processing
Keepa
- ⚠️ Uploads price data to their servers
- ⚠️ Requires account (email collection)
- ⚠️ Cloud-based processing
Honest Price Tracker:
- ✅ All data stays local
- ✅ No account required
- ✅ On-device processing
Technical Architecture (For Transparency)
// This code runs ONLY in your browser
function extractAmazonPrice() {
// Read price from the page you're viewing
const price = document.querySelector('.a-price-whole')?.textContent;
// Store locally in YOUR browser
chrome.storage.local.set({ currentPrice: price });
// NO network request is made
// NO data is uploaded
}
Offline Test
You can verify our privacy commitment:
- Disconnect your internet
- Use the extension (track products, view history)
- Everything still works
Why? Because we never need to contact any server. Everything runs on your device.
