Royalty tracking for self-published authors

Your royalties, with receipts.

Drop in your KDP reports. Aldus reads them on your device and builds a ledger of royalties, units and page reads, with the source behind every number. No store login. No cookies.

Free during early access.

Numbers you can check.

Before

  • A connection that keeps breaking.
  • Store cookies handed to someone else.
  • Estimates that look like final numbers.

With Aldus

  • A ledger built from your own report files.
  • Files read on your device, with no store login.
  • Every number marked estimated or final.

How it works

  1. Step 1

    Download a report from KDP

    Use the report files you already download from your KDP account, as .xlsx or .csv.
  2. Step 2

    Drop it into Aldus

    Aldus reads the file on your device and shows what it found before anything is added. You can add several files at once.
  3. Step 3

    Read your ledger

    Royalties, units and page reads, with each figure marked estimated or final and traceable to the report it came from.

What you see

Estimated and final, marked

Every figure shows how much of it is final and how much is still an estimate. An estimate is never presented as a final number.

The source of every number

Each figure can be traced to the report it came from and to when that report was downloaded.

No double counting

Import the same report twice and Aldus recognises it. Nothing is added to your ledger a second time.

Catalog and import history

Your titles are listed from the rows you import, and every import is recorded so you can see what was added and when.

What leaves your device

Your report files are read in your browser. Aldus sends only the rows it needs to build your ledger. The file itself stays on your device, and Aldus never asks for your store password or cookies.

Aldus updates when you import a report. It does not collect anything on its own.

Questions

Does Aldus need my KDP password or cookies?

No. Aldus never asks for your store password or cookies and never signs in to your store account. You download your report files yourself and Aldus reads them on your device. Amazon endorses no royalty tracker, and your store's terms still apply to you.

Is importing files a lot of work?

You download a report, drop it into Aldus and review what was found. You can add several files at once. Aldus updates only when you import a report; it does not collect anything while your browser is closed.

Will the numbers match my store's reports?

Aldus builds your ledger from the rows in your own reports. Estimates are marked as estimates, and final figures come from the store's finalized reports. Every figure is traceable to the report it came from, so you can check it.

I have years of history in another tracker. Can I bring it?

History comes from the store's own report files, so you do not need an export from another tracker. Import the reports for the periods you want.

Which stores does Aldus read?

KDP reports today. Other stores are planned and are not available yet.

What does it cost?

Aldus is free during early access, with every feature included. Paid plans are not open.
