What AuthorTally is
AuthorTally is a browser-based tool that reads report files you export from your own Amazon Ads and KDP accounts and computes summaries of them on your device. AuthorTally is not affiliated with, endorsed by, or connected to Amazon.com, Inc. or its subsidiaries. Amazon, Kindle, and KDP are trademarks of Amazon.com, Inc.
Your license
A purchase gives one person a perpetual license to use the version of AuthorTally they bought, for their own publishing catalog (all of your own pen names count as you). It includes 12 months of updates and report-format fixes from the date of purchase. After 12 months the tool continues to work; major new versions may be offered as optional paid upgrades. Licenses are not transferable and may not be shared, resold, or used to provide services to third parties.
Our end-of-life promise
If AuthorTally is ever discontinued, license holders will be offered a downloadable offline copy of the tool that runs without our servers, with activation removed.
Estimates, not advice
AuthorTally produces estimates and summaries, not facts about the future and not financial advice. Figures based on Kindle Unlimited page reads use per-page rates that Amazon finalizes only after month end, and are labeled estimated. Advertising attribution figures come from Amazon and are subject to Amazon's own attribution windows and revisions. You are responsible for your own advertising, publishing, and financial decisions.

Warranty and liability
AuthorTally is provided "as is" without warranties of any kind. To the maximum extent permitted by law, our total liability for any claim related to AuthorTally is limited to the amount you paid for your license.
Changes
We may update these terms; material changes will be posted on this page with a new date. Continued use after a change means acceptance.
