ArcSignal: Smart Price Tracking for Better Buying Decisions

Know whether a price is worth buying before you check out.

ArcSignal helps you make smarter shopping decisions by tracking product prices over time, showing historical trends, and notifying you when prices change. Instead of guessing whether today's price is a good deal, you can compare it with previous prices and decide whether to buy now or continue watching.

Designed with privacy in mind, ArcSignal works directly in your browser without requiring an account. Your tracked products stay on your device, giving you full control over your data.

HOW IT WORKS

Visit a supported product page and select Track to begin monitoring the item. ArcSignal records the current price, builds a price history over time, and automatically checks for changes in the background. You'll receive a notification when the price drops or reaches a target that you choose.

The extension also analyzes each product's historical pricing to help you understand whether the current price is competitive based on previous trends.

PRIVACY FIRST
