Overview

Track prices, catch drops, and buy at the right time. A fast, clean, privacy-first price tracker for serious online shoppers.

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. FEATURES • Track products with a single click • View historical price trends for tracked products • Receive automatic price drop notifications • Create custom target price alerts • Get simple Buy, Wait, or Watch recommendations based on price history • Organize products in a single watchlist • Import and export your tracked items • Share watchlists when needed • Convert prices between supported currencies • Access tracking from the page, popup, or context menu PRIVACY FIRST ArcSignal is built to respect your privacy. No account is required to start tracking products. Your watchlist and settings remain stored locally in your browser unless you choose to export them. ArcSignal does not sell your information, inject affiliate links, or modify the products you visit. SUPPORTED RETAILERS ArcSignal works across many popular online retailers, with additional store support added over time. FREEE & PRO The free version lets you begin tracking products immediately. Users who need additional capacity and advanced monitoring features can upgrade to ArcSignal Pro directly from within the extension. Whether you're waiting for a seasonal sale, monitoring an expensive purchase, or simply making sure you're getting a fair price, ArcSignal provides the information you need to shop with greater confidence.
