In short

Your report file is read in your browser. The file is not uploaded or stored on Aldus’s servers.
Aldus sends the rows it read, a file fingerprint and a few details of the file.
Aldus never asks for a store password or cookies and never signs in to a store account.
What is sent is used only to provide Aldus to you.

On this page

Sent for each row of a report

Date: Places each amount in the right day or month.
Marketplace: Splits your totals by store.
Title: Builds your catalog.
Author: Groups editions of the same book.
Book identifier: The ASIN or ISBN tells one edition from another.
Format: Separates eBook, paperback and hardcover.
Units: Sold, refunded, net and ordered units, as the report states them.
Page reads: Kindle Unlimited pages read.
Royalty amount: What each row earned.
Currency: Keeps amounts in the currency the store paid in.
Royalty rate and sale type: Tells a standard sale from a free promotion, a page read or an order.
Average prices and costs: List price, offer price, delivery or printing cost and file size, as the report states them.
Estimated or final: So an estimate is never shown as final.
Sheet name: So every number can show which part of the report it came from.
Row and book keys: Built on this device from the fields above, so the same row is never counted twice.

Sent for each file

File name: Shown in your import history.
File size: Shown in your import history.
Time the file was saved: Tells a newer download from an older one.
File fingerprint: A short code computed from the file, used to recognize a file you already imported. The file can’t be rebuilt from it.
Date range you downloaded: Only if you set it. Days in the range with no rows then count as days with no sales.
Report type: Which KDP report this is, and whether it is estimated or final.
Reader version: Which version of Aldus’s report reader understood the file.
Notes about skipped rows: How many rows were left out and why, with sheet and column names and row numbers. Never the values in those rows.
Position in a large file: Large files are sent in several pieces; this says which piece and which import it belongs to.

The file fingerprint is a SHA-256 digest of the file. Before you choose Add to ledger, it is the only thing sent, to check whether you already imported that file.

What never leaves your device

Your store password. Aldus never asks for it.
Cookies or a session from your store account. Aldus never signs in to it.
The values in rows the reader left out.
