Market Arc 作者： Market Arc

Note on permissions: This extension only reads product prices from pages you explicitly open. It does not access your banking, email, or any sensitive sites. It activates only when you click the Market Arc icon.
Market Arc tracks prices on any website and emails you
the instant they drop — so you never overpay again.

How it works:
1. Create a free account with your email
2. Open any product page and click the Market Arc icon
3. We check prices automatically every hour
4. The moment a price drops, you get an instant email alert

Works on multiple stores. Free plan available. No ads. No tracking.
