Privacy Policy

Effective 17 August 2026 · Last updated 17 August 2026

AZ Sales is a Chrome extension that estimates daily sales, Best Sellers Rank and net profit after Amazon fees on Amazon product, search and Best-Sellers pages. This policy explains exactly what data the extension and this website handle, why, where it is kept, how long for, and who else sees it.

The extension and this website are operated by Tony / Shopverix ("we", "us"). Contact: support@shopverix.com.

1. What the extension does

AZ Sales has a single purpose: showing sales, rank and profit estimates for Amazon listings. To do that it reads the Amazon page you are already viewing and, for listings whose rank is not shown on that page, fetches the product's own Amazon page in the background using your existing browser session. All of that reading and calculating happens on your device. The results are shown to you and cached locally; they are not transmitted to us.

2. Data we collect

2.1 If you do not sign in

Nothing is collected by us. The free preview works entirely locally. No account is created, no request carrying personal data is sent to our servers, and we have no way to identify you.

2.2 Account data (only if you create an account)

You can sign in with Google or with a one-time code sent to your email address. In either case we receive and store:

• Your email address.
• An account identifier (a random UUID generated by our authentication provider).
• Account timestamps — when the account was created, and when your free trial starts and ends.

We never receive your Google password. When you sign in with Google we receive only your email address and that identifier — not your contacts, calendar, Drive, profile details or any other Google data.

2.3 Subscription and referral data

• Subscription status (none, trialing, active, past due, or cancelled) and the date your current billing period ends.
• A Stripe customer identifier, so we can match your account to your subscription.
• Referral data — your own referral code, the code you were referred by if any, and the count of bonus days and credited referrals.

We never see or store your card details. Payment is taken on Stripe's own hosted checkout page; card numbers go directly to Stripe and never pass through the extension or our servers.

2.4 Data that stays on your device and is never sent to us

The extension stores several things in your browser's local storage. None of it is transmitted to us or to anyone else, and it is all removed when you uninstall the extension or clear the site's data:

• Your sign-in session and a cached copy of your subscription status, so you are not asked to sign in repeatedly.
• Free-preview usage — the distinct Amazon search terms you have used during the free preview, held locally purely to count how many of your free searches remain. These search terms never leave your device.
• A pending referral code, if you arrived through an invite link.
• A cache of Amazon data — ranks, categories, dimensions, weights, seller countries and rate-limit state — so the extension does not re-request the same page. This is Amazon's public product data, not personal data, and it expires automatically.
• Your extension settings, such as whether sponsored listings are hidden and whether rank and country lookups are enabled.

2.5 What we do not collect

• We do not collect your browsing history, and the extension does not run on any site other than Amazon marketplaces and our own website.
• We do not receive the Amazon products, searches or pages you view.
• We use no analytics, telemetry, tracking pixels, advertising or fingerprinting of any kind — there are none in the extension or on this website.
• We do not collect your name, address, phone number, location, IP-based profile, health, financial or biometric data.
• We do not read or store your Amazon account credentials.

3. How we use the data

We do not use any of this for advertising, profiling, automated decision-making, or any purpose unrelated to running the extension and your subscription. We do not send marketing email unless you ask us to.

4. How the data is stored and protected

• Account and subscription data is held in a Supabase (PostgreSQL) database, hosted on Amazon Web Services infrastructure.
• Access is restricted by row-level security, so an authenticated user can read only their own record.
• All traffic between the extension, this website, our billing service and our database is encrypted in transit over HTTPS/TLS.
• Our billing service holds no database of its own; it validates your sign-in token and talks to Stripe and Supabase over HTTPS.
• Administrative access is limited to the operator of the service.

No system is perfectly secure, and we cannot guarantee absolute security. If a breach ever affects your data we will notify affected users by email without undue delay.

5. How long we keep it (data retention)

• Account data — kept while your account exists. If you ask us to delete your account, we remove your account record and associated referral and subscription rows within 30 days.
• Payment records — Stripe retains transaction records under its own policy, and we may retain invoice and tax records for up to 7 years where accounting and tax law requires it. These contain your billing details as held by Stripe, not card numbers held by us.
• Local data on your device — kept until it expires, until you clear your browser data, or until you uninstall the extension, whichever is first. The Amazon data cache expires automatically within 24 hours to 30 days depending on the item.

6. Who we share it with

We do not sell, rent or trade your personal data, and we never have. We share data only with the service providers needed to run the product, each of which acts as our processor under its own privacy policy:

We may also disclose data if legally required to do so — for example in response to a valid court order — or to establish or defend legal claims. If the service is ever sold or transferred, account data may transfer with it, and we will say so here before that takes effect.

Amazon. The extension requests Amazon pages from your browser using your existing Amazon session, exactly as if you had opened those pages yourself. Amazon therefore sees those requests as your own browsing. We receive none of it.

7. Chrome Web Store Limited Use disclosure

Our use of information received from Google APIs, and of any user data obtained through the extension, adheres to the Chrome Web Store User Data Policy, including its Limited Use requirements. Specifically:

• We use the data only to provide and improve the single purpose described in section 1.
• We do not transfer the data to third parties except as listed in section 6, and never for advertising or resale.
• We do not use or transfer the data to determine creditworthiness or for lending purposes.
• No humans read your data except where you have explicitly asked us to (for example, when you contact support), where required by law, or for security purposes such as investigating abuse.

8. Permissions, and why each one is needed

9. Your rights and choices

• Use it without an account. The free preview requires no sign-in and sends us nothing.
• Access or export. Ask us and we will send you a copy of the data held about you.
• Correction. Ask us to correct anything inaccurate.
• Deletion. Ask us to delete your account and we will do so within 30 days, subject to the payment records noted in section 5.
• Withdraw consent. Cancel your subscription at any time from the account page, and uninstall the extension to remove all local data.
• Object or restrict. Where the GDPR or similar law applies, you may object to or ask us to restrict our processing, and you may complain to your local data protection authority.

To exercise any of these, email support@shopverix.com. We aim to respond within 30 days. We will not charge you or degrade the service for exercising a right.

10. International transfers

Our service providers operate globally, and your data may be stored or processed outside your country, including in the United States. Where data is transferred out of the UK or European Economic Area, our providers rely on appropriate safeguards such as the European Commission's Standard Contractual Clauses.

11. Children

AZ Sales is a business tool for Amazon sellers and researchers. It is not directed at children, and we do not knowingly collect data from anyone under 16. If you believe a child has given us data, email us and we will delete it.

12. Changes to this policy

If this policy changes we will update the date at the top and publish the new version at this address. If a change materially affects how we handle your data, we will also notify account holders by email before it takes effect. Continuing to use AZ Sales after a change means you accept the updated policy.
