ListingLens — Privacy Policy

Effective July 7, 2026

The short version: ListingLens runs entirely in your browser. We do not collect, store, transmit, or sell any of your data. The listing pages you view are analyzed locally on your device and never leave it.

What ListingLens does

ListingLens is a Chrome extension that analyzes the Etsy listing page you are currently viewing and displays an optimization checklist. All analysis happens locally in your browser. The extension has no servers, no analytics, no trackers, and requires no account.

Data we collect

None. ListingLens does not collect personal information, browsing history, page content, shop data, or usage statistics. Page content is read only in your browser's memory to produce the checklist you see, and is discarded when you leave the page.

Data stored on your device

Your preferences (such as the auto-open setting) are stored using Chrome's built-in extension storage, which may sync across your own Chrome profiles if you have Chrome sync enabled. This data never reaches us.

Payments

Optional Pro subscriptions are processed by ExtensionPay and Stripe. If you start a trial or subscribe, your email address and payment details are collected and processed by those services under their own privacy policies (ExtensionPay's policy, Stripe's policy). ListingLens itself never sees your payment details. If you never subscribe, the extension's only network activity is a license status check with ExtensionPay, which does not include any personal information or page content.

Data sharing and sale

We do not share or sell data — we have none to share or sell.

Changes

If this policy ever changes, the updated version will be posted at this address with a new effective date. Material changes will be noted in the extension's changelog.
