SpendGuard for Amazon™

Track your Amazon spending without sharing data with anyone.

Curious how much you have spent on Amazon lately? SpendGuard shows your 30-day and 3-month spending totals in a small floating widget right on Amazon pages. Everything runs locally in your browser: no external servers, no tracking, no data collection.

Features: See your spending totals at a glance. Get a yellow warning on checkout pages reminding you how much you have already spent. Block Amazon during specific hours if you need a break. Drag, minimize, or refresh the widget anytime. Works across 21 Amazon regions including US, UK, DE, FR, IT, ES, JP, CA, AU, and more.

How it works: Just visit any Amazon page and the widget appears automatically. It reads your order history to calculate totals, then remembers the data for 24 hours so it loads instantly. Need fresh numbers? Click refresh.

Privacy: Your data stays on your device. Always. The extension reads your Amazon order history locally and stores totals in Chrome's local storage. No servers. No tracking. No accounts. Fully open source.
