Privacy & data
We never see the products you run.
Not as a policy choice — as an architectural one. The calculation happens entirely in your browser, so there is no server holding your products, your costs or your margins. There is nothing for us to look at, sell or lose.
Last updated 23 September 2026.
What is stored, and where
Eight things, all in your own browser’s local storage on your own device. No server, no database, no account.
| What | Contains | Nature |
|---|---|---|
| Your saved products | Every product you save and the figures you entered — price, cost, weight, dimensions, volumes. | Commercially sensitive. Never leaves your browser. |
| Your licence | Your licence key, tier, purchase date, the email used at purchase and the activation id. | Contains personal data. |
| Your email address | The address given at the free-tier gate, if you used one. | Contains personal data. |
| Which marketplaces you have used | Marketplace codes only, to apply the free tier’s single-market limit. | Not personal data. |
| Your report branding | Firm name, client names and an uploaded logo, if you use white-label reports. | May contain a third party’s data. |
| Your report preferences | Which sections of a report you switch on. | Not personal data. |
| Your exchange-rate overrides | Any rate you have chosen to replace. | Not personal data. |
| Your answer on partner referrals | Whether you allowed a partner’s referral to be recorded, if you were ever asked. | Not personal data. |
What leaves your browser
Five destinations. There are no others.
-
Our own servers
Requests for the app’s own code and its fee-data files. These carry nothing about you or your products — they are the same files every visitor receives.
-
Lemon Squeezy, when you activate a licence
Your licence key and a device label such as “AMZ Verdict — macOS — 2026-08-29”, so the three-device limit can be applied. Lemon Squeezy is also the merchant of record for the purchase itself: card details never touch this site, so we cannot leak them — we never have them.
-
Google, only if you press “Continue with Google”
The “Continue with Google” script is loaded only when you press that button — not when the page loads, and not merely because a sign-in gate is on screen. Until you press it, the button is ours and Google has not been contacted. A licence holder never contacts Google at all, and neither does anyone reading the free tools. If you use the plain email option instead, Google is never contacted.
-
Lemon Squeezy, only if you arrived through a partner’s link and chose “Allow”
The page address you arrived on, the referring page, the partner’s referral id and an identifier derived from your browser, so the partner can be credited if you buy. It sets one cookie,
ls_aff_ref. Nothing about your products or figures is sent. If you chose “No thanks”, or arrived any other way, nothing is loaded from Lemon Squeezy. -
Mailchimp, when you give us an email address
The address itself, and nothing else — not the products you have run, not your costs, not your margins, because those never leave your browser at all. It is sent so we can write to you occasionally about AMZ Verdict. Use the unsubscribe link at the foot of any email we send, or write to [email protected] and we will remove you.
Your email address
The free tier asks for an email address before it shows a verdict. The free tools at /tools/ do not ask for one at all.
To be removed: Use the unsubscribe link at the foot of any email we send, or write to [email protected] and we will remove you. Clearing this site’s browser data also removes the copy held on your own device.
Analytics, advertising and tracking
We use privacy-preserving website analytics to see which pages are read: no cookies, no personal data, no cross-site tracking and no profile of you. There is no advertising pixel, no tag manager, no data broker and no error-reporting service. Typefaces are served from our own domain rather than a font network, so reading this page tells no third party that you did.
The one exception is affiliate links, and only if you agree. If you arrive through a
partner’s referral link (a web address containing ?aff=), we ask first. Only if you
choose Allow does Lemon Squeezy’s affiliate script load: it records the referral
with Lemon Squeezy, using an identifier derived from your browser, and sets one cookie,
ls_aff_ref, so the partner is credited if you later buy. If you choose No
thanks, or did not arrive through such a link, nothing is loaded from Lemon Squeezy and nothing
is recorded. We remember your answer on this device; clearing this site’s browser data resets it.
Your rights, and how to use them
Most data-protection rights concern data a company holds about you. We hold almost none, which makes most of them straightforward:
- Access and portability — everything about your products is already on your device, and the Excel export gives you all of it in a portable format.
- Erasure — clearing this site’s browser data erases everything listed above, immediately and irreversibly.
- Purchase records — your order and invoice are held by Lemon Squeezy as merchant of record; their privacy policy governs them, and requests about payment data go to them.
- Anything else — write to [email protected] and we will answer.
Questions about any of this
[email protected]. AMZ Verdict is used by sellers across 11 marketplaces, most of them in the European Union, so this is written to the standard the GDPR sets.
