05 — Questions
Questions, answered
Where does the data come from?
Directly from Amazon KDP and Amazon Advertising via their official APIs (Meta support is coming soon). Product and rank data is enriched from Amazon’s public listings. Nothing is entered by hand.
Is connecting my Amazon account safe?
We use read-only reporting and advertising scopes. We never see or store your Amazon password, and we never write to your account.
What makes AuthorLens different?
One honest profit number instead of three dashboards to reconcile by hand. Your earnings and ad spend are matched per book and refreshed daily, with YouTube and TikTok ad tracking on the way.
Does it cover print and audiobooks?
Yes. Paperback, hardcover and ACX audiobook royalties all roll into net profit alongside eBooks and Kindle Unlimited page reads.
