About CartWatch - Amazon Budget & Spending Tracker

It's easy to overspend on Amazon. A few quick purchases here and there, made without much thought, and before you know it you've spent far more than you meant to. CartWatch helps you keep control of your Amazon spending. Set a monthly budget and stick to it, see at a glance whether you're over or under, and compare your spending month to month — so you always know how much you're spending, and where it's going. HOW IT WORKS Open CartWatch while logged in to Amazon and it scans your order history automatically. Set a monthly budget once, and CartWatch keeps a running total of what you've spent, what's left, and whether you're on track — updating itself every time you open the popup. FEATURES • Set a monthly budget and see spending vs. remaining budget at a glance • Browse spending history by month, with full order details and amounts • Trends tab: compare spending over time with average, median, high, and low stats, sortable by month, order count, or total • Filter orders by recipient to see who's spending what • Flags refunded, cancelled, and returning orders, and adjusts your spending total automatically — no manual math • All data stored locally on your device — nothing is ever sent to a server • Take a break with Bricks, a built-in Breakout-style mini-game, right from the popup PRIVACY CartWatch only reads your own Amazon order history pages and stores everything in your browser's local storage. No accounts, no servers, no tracking — your data never leaves your device. SUPPORTED REGIONS amazon.com, amazon.co.uk, amazon.ca, amazon.com.au, amazon.in GETTING STARTED Make sure you're logged in to Amazon, then open CartWatch. It scans the current month automatically — just set a budget and you're done.
