Controller

Shortlist This is provided by Finnzon Oy, Business ID 2849466-3, c/o Jussi Hyvärinen, Ankkurinvarsi 17, 02320 Espoo, Finland.

Finnzon Oy is the data controller for the service data it receives, which is limited to license and billing data: anonymous installation identifiers, license entitlement status, customer email addresses used for billing and purchase restoration, and technical request metadata used for rate limiting and billing security.

Privacy contact: info@finnzon.com.

Overview

Shortlist This is a Chrome extension that filters and ranks the products visible on an Amazon search page. It processes the current Amazon search page and your structured filter settings locally in your browser.

The analysis is deterministic — explicit parsing and scoring rules, no AI — and it runs only after you click the analysis button on a page you intentionally opened.

The marketing website at shortlistthis.com uses Umami website analytics, described below. The extension package itself contains no analytics of any kind.

What is not collected

The extension does not transmit Amazon search queries, product titles, ASINs, prices, shortlist contents, filter settings, or browsing history to anyone — including Finnzon.

It does not use analytics, advertising trackers, AI services, Amazon APIs, or affiliate-link rewriting. Product links are never modified.

It does not collect location, keystrokes, clipboard contents, payment card numbers, passwords, or authentication credentials.

Local storage

The extension stores your filter settings, trial usage, and license state in Chrome local storage on your device.

Trial usage is recorded as hashed search-session identifiers, so the trial record never contains your search text itself.

A saved billing email, if you provide one, is stored locally to prefill checkout and purchase restoration. It is sent to Finnzon only when you start checkout, restore a purchase, or validate a license.

License service and payments

For checkout, purchase restoration, and periodic license validation, the extension contacts the Finnzon license service and sends only the Shortlist This product code, a random extension installation identifier, and the email address you explicitly provide. No Amazon, shortlist, or filter data is ever included.

Stripe processes the payment checkout on Stripe-hosted pages. Card and payment method details are entered on Stripe's pages, never in the extension. Stripe may also act as an independent controller for fraud prevention, legal compliance, and payment network obligations.

Restoring a purchase to another installation requires a six-digit code sent to the billing email. Finnzon stores only a keyed digest of the code with its installation binding and expiry.

Permissions

The extension requests access only to Amazon.com and Amazon.de pages, Chrome local storage, and the Finnzon license endpoint origin.

It analyzes only product result cards already loaded on a search page you intentionally opened, and only after you click the analysis button. Nothing runs in the background, and no additional pages are ever opened or crawled.

Chrome Web Store Limited Use

Finnzon's use of information received from Chrome extension permissions complies with the Chrome Web Store User Data Policy, including the Limited Use requirements.

Data accessed through extension permissions is used only to provide the extension's single purpose: filtering and ranking the products visible on the Amazon search page you choose, managing local settings, and handling license status.

Finnzon does not sell user data and does not transfer user data to advertising platforms or data brokers.

Website analytics

The shortlistthis.com website uses Umami, a privacy-focused analytics service, to measure aggregate website usage — page views, referrers, approximate location, and device and browser information.

This analytics runs only on the public website. It is not present in the Chrome extension, and it is never connected to what you search or shortlist on Amazon.

Retention

Local settings, trial state, and license state remain in Chrome storage until you remove the extension or clear extension data.

Finnzon retains license entitlement, billing, technical audit, and website analytics data for as long as needed to provide the service, prevent abuse, meet accounting or legal obligations, and understand public website usage.

Independence

Shortlist This is an independent browser extension and is not affiliated with, endorsed by, or sponsored by Amazon.

Your controls

You can remove the extension or clear Chrome extension storage at any time to delete all locally stored settings, trial state, and license state.

You may contact Finnzon to request access, correction, deletion, restriction, objection, or portability of your billing data where applicable under data protection law.
