What It Is

Amazon Spending Tracker is a free Chrome extension that tracks how much users spend on Amazon each year. It uses Google OAuth2 to obtain read-only access to Gmail, searches for Amazon order confirmation emails, parses order amounts, and displays annual spending, order count, average order value, average monthly spend, monthly trends, and recent order details in the extension interface.

Core Capabilities and Technical Boundaries

The tool’s biggest distinguishing feature is local processing: the page clearly states that there are no external servers, that data never leaves the browser, and that it is stored in chrome.storage.local. It only reads emails in Gmail from auto-confirm@amazon. and ship-confirm@amazon., and does not modify email content. Supported Amazon marketplaces include Spain, the United States, Germany, France, Italy, and the United Kingdom, and it can recognize both European and US-style currency formats.

Pricing and Open Source

The product is clearly labeled as a free Chrome Extension, with no mention of subscriptions, in-app purchases, or paid premium tiers. The official site also describes it as an open-source tool, but the captured text does not provide a code repository URL, so its license, maintenance activity, and contribution process cannot be further assessed.

Pros and Cons

Its advantages are a low barrier to entry, a clear privacy design, no need to export Amazon data, and no need to send emails to a third-party server. Hourly background syncing and a real-time badge on the extension icon are also convenient for everyday checking. The drawbacks are equally clear: it depends on Gmail and order confirmation emails, so the results are only estimates based on email parsing and may be affected by missing emails, email format changes, refunds, or canceled orders. It also only supports Chrome and 6 country marketplaces, and lacks an API, SDK, team features, and more advanced budget analysis.

Who It’s For and Access from China

It is suitable for individual users who want a quick view of their annual Amazon spending, especially those who have long used Gmail to receive Amazon order emails. It is not well suited to corporate procurement, finance reimbursement, or multi-platform spending management. Access from China cannot be confirmed from the text; because the product depends on Gmail and the Chrome Web Store, domestic users may face additional network and account-related restrictions. Alternatives could include Amazon order history, credit card statements, or local budgeting apps.
