Address Alert

Warns you before accidentally shipping to a saved danger address.

Address Alert: Fail-safe shipping protection. Never ship to your old apartment, office, or an incorrect saved address again! Address Alert is a privacy-focused, zero-leak browser extension that acts as your shipping safety net. It runs entirely locally in your browser, keeping your personal data 100% secure. Add your "danger addresses" to your watchlist, and Address Alert will automatically scan checkout forms in real-time, displaying a nuclear-level red warning banner if you are about to confirm a shipment to a wrong address. Features: Real-time Scan: Automatic background detection on checkouts (Amazon, Shopify, and any online retail store). Privacy First: 100% local storage. Your address never leaves your computer. Exclusions & Wildcards: Easily snooze warnings or exclude specific domains and patterns from scan triggers. Cross-Browser Support: Lightweight, highly optimized, and optimized for mobile or desktop form-factors.
