Overview
PriceHistoryX tracks the real prices of products you visit on Amazon, Walmart, Target, and Best Buy — so you always know when you're getting a true deal.
HOW IT WORKS
- Visit any supported product page → PriceHistoryX automatically records the current price.
- As prices change over time, you build up a private price history.
- A deal-score badge appears on the product page showing Lowest / Average / Highest price and how today's price compares.
- Track a product to get browser notifications when its price drops by a configurable threshold.
PRIVACY-FIRST
- All price data is stored locally on YOUR device — never on our servers.
- No telemetry, no tracking, no analytics, no ads, no account required.
- The extension only communicates with: the retail sites you visit, and api.freemius.com (for license verification, only if you upgrade to a paid plan).
- Full privacy policy: https://excesspronet.com/privacy-policy/
