KDP Royalty Tracker

Private, on-device dashboard for your Amazon KDP payments & royalties. No servers, no credentials — your data stays in your browser.

Make sense of your Amazon KDP earnings — without the spreadsheets. KDP Royalty Tracker is a private, on-device Chrome extension for Amazon KDP authors. It turns the Royalties Estimator data you already get from Kindle Direct Publishing into clear, interactive dashboards — so you can see how your books are really doing without wrestling with exports and pivot tables. Private by design. There are no servers, no sign-up, and no Amazon credentials. The extension reads the report from the KDP Reports site you're already logged into, and stores everything locally in your own browser. Your sales data never leaves your machine. You stay in control. When you import your figures, the extension simply clicks the KDP page's own "Download Report" button once — one human-equivalent click — and reads the result. It never logs in for you, never stores your password, and never sends your data anywhere. Prefer to do it yourself? Drag and drop a report you've already downloaded instead. Either way, everything is processed and stored on-device. The Royalties Estimator dashboard gives you: • Daily trends — watch your estimated royalties build day by day, with a chart that makes good (and quiet) spells easy to spot. • Earnings by format — split across eBook, paperback, hardcover, and Kindle Unlimited KENP pages read, all in one view. • Earnings by marketplace — see how each Amazon store contributes, converted into a single display currency you choose, with editable exchange rates. • Best-selling titles & headline KPIs — see what's working without any number-crunching. • Powerful filters — filter by date, format, and marketplace to zoom in on a single book, a single store, or a particular stretch of time. Kindle Unlimited (KENP) — see pages read, and optionally estimate KU earnings with an editable per-page rate. Your data stays yours. Everything is stored locally in your browser — no account, no upload, just your numbers when you need them. Built by Rectangle Red, part of our Apps range.
