Nothing to hide, because nothing is collected.

Last updated: July 2026

Core principle

Listing Clarity has no analytics, no tracking, and no data collection server. All analysis happens locally in your browser.

What the extension processes

Etsy page content: The extension reads titles, tags, prices, and review counts from Etsy pages you are viewing. This analysis runs on your device and the results never leave it.
Usage counter: The free plan's daily analysis count is stored in your browser's local storage only. It is never transmitted anywhere.
License keys (Pro): If you activate a Pro license, your license key is sent to Polar — our payment provider — solely to verify it. The key is stored locally in your browser. This is the extension's only network request.

What does not happen

No analytics or telemetry
No collection of browsing history
No capture of your Etsy account data
No cookies, no fingerprinting
No sharing of any data with third parties

Payments

Pro subscriptions are sold by Polar (polar.sh) as the merchant of record. Polar processes your payment details under its own privacy policy; we never see your payment information.

Service providers (sub-processors)

Two third parties are involved in running Listing Clarity, and only in the narrow roles described here:

Polar Software Inc. (polar.sh): Payment processing and license key management for Pro subscriptions, as merchant of record. Receives your license key on activation and your payment details at checkout. Data processing under Polar's own privacy policy and data processing agreement.
GitHub, Inc. (GitHub Pages): Hosts this website. Like any web host, GitHub receives standard server logs (IP address, requested page) when you visit this site. The extension itself never talks to GitHub.

There are no other sub-processors: no analytics vendors, no advertising networks, no CRM, no email marketing platform.

Your rights

Since we store no personal data on any server, a GDPR access or deletion request has nothing to return on our side. All extension data lives in your browser and is removed when you uninstall the extension. For anything else, email keanu@knudev.de.

Listing Clarity is independent and not affiliated with Etsy, Inc.
