Privacy-First Price Comparison: Why Your Shopping Data Should Stay Yours

If you're not paying for a product, you are the product. It's a cliché because it's true. But what if there was another way?

Most free browser extensions make money by collecting your browsing history-every site you visit, every click you make-and selling it to data brokers. This data is used to build a profile of you that advertisers use to target you with eerie precision.

The Data Economy of Browser Extensions

Here's how the typical "free" shopping extension works:

  1. You install the extension to save money.
  2. The extension asks for permission to "read and change all your data on the websites you visit."
  3. It tracks every URL you visit, not just shopping sites.
  4. It packages this "clickstream data" and sells it to hedge funds, marketing firms, and competitors.

This is a multi-billion dollar industry operating in the shadows.

The FindPrices Approach: Privacy by Design

We believe your shopping history is nobody's business but your own. That's why we built FindPrices with a "Privacy First" architecture.

1. No Browsing History Collection

We literally do not track your browsing history. We don't have a database of the sites you visit. We don't want one. It's a liability we refuse to take on.

2. Local processing

When you visit a product page, our extension analyzes the page locally on your computer to identify the product. It sends a specific query to our API saying "What is the price for [Product X]?" rather than "User [Name] is visiting [URL]."

3. Anonymous Queries

Our API queries are designed to be anonymous. We don't attach enduring user IDs to price checks. We just return the data.

4. Revenue from Results, Not Surveillance

We make money when you actually find a deal and buy it. If you click a link to a retailer and make a purchase, we earn a commission. This business model is transparent and aligns our incentives with yours: we only get paid if we provide value.

Why Does Privacy Matter in Shopping?

It's just shopping, right? Who cares if someone knows I bought socks?

But shopping data reveals much more than just purchases. It effectively reveals:

When aggregate data is sold, it can be de-anonymized. Researchers have repeatedly shown that "anonymous" browsing data can be linked back to specific individuals with frightening ease.

The Future is Private

Consumers are waking up. We're seeing a massive shift towards privacy-respecting tools like Signal, DuckDuckGo, and Brave. FindPrices is bringing that same philosophy to e-commerce.

You shouldn't have to trade your privacy to save $10 on a toaster. With FindPrices, you don't have to.
