Privacy policy

Overview

This Privacy Policy explains how Q-MER.CH collects, uses, stores, and shares information when you use Q-MER.CH, QST Listing Workspace, QST Desktop, our website, our downloads, our support channels, and related services.

In this policy, "Q-MER.CH", "we", "us", and "our" refer to Q-MER.CH. "You" means the person, business, merchant, store, customer, or visitor using our website, products, services, software, downloads, documentation, or support.

QST Listing Workspace helps merchants review store product data, prepare marketplace-ready listing drafts, save preparation records, and download export files. The Shopify Admin app uses read-only product access for its main workflow and does not write product changes back to your Shopify catalogue.

QST Desktop is an optional Windows companion for merchants who want advanced local workflows. QST Listing Workspace can be used without installing QST Desktop.

Information We Collect From Website Visitors And Customers

When you visit Q-MER.CH, contact us, or buy something from us, we may collect:

device and browser information, such as browser version, IP address, time zone, cookie information, pages viewed, referring pages, search terms, and how you interact with the site
order and checkout information, such as name, billing address, shipping address, email address, phone number, payment confirmation details, products purchased, and order history
customer support information, such as your email address, messages, screenshots, files you choose to send, and information needed to respond to your request
marketing and communication preferences, where you choose to provide them

Payment card details are processed by Shopify or payment providers. We do not need you to send full card numbers, passwords, API keys, recovery codes, or private access tokens through support channels.

Information QST Listing Workspace Processes

When a merchant installs or uses QST Listing Workspace, QST may process:

Shopify shop domain and app installation context
Shopify access tokens needed to authenticate the installed app
Shopify product data made available through the app's read_products scope, such as titles, descriptions, handles, vendors, product types, tags, statuses, images, variants, prices, SKUs, and inventory quantities
listing draft and export-preparation records created by the merchant
export activity records, such as export type, product count, filenames, and timestamps
app plan, subscription, trial, and billing status information received through Shopify billing or app installation context
optional desktop pairing codes, pairing status, and desktop pairing tokens
technical logs needed to operate, secure, monitor, and troubleshoot the app

QST Listing Workspace does not request Shopify customer, order, payment, fulfilment, or write-product scopes for the Shopify Admin app.

Information QST Desktop May Process

If you choose to use QST Desktop, the desktop app may process or store information on your Windows device, including:

local preferences and setup choices
desktop pairing tokens and connection settings
product caches and export working files
local listing drafts, image choices, and prepared listing files
diagnostic logs and error messages
optional marketplace credentials or OAuth tokens if you connect a marketplace account through QST Desktop

Optional eBay authentication is only used if you choose to connect eBay for a desktop workflow. The core Shopify Admin app review and export workflow does not require an eBay account.

Browser Local Storage

QST Listing Workspace may store some local draft edits, image choices, setup notes, or interface preferences in your browser local storage so your work can survive a refresh. This browser-local data is stored on the device and browser you are using.

You can clear browser-local QST draft data from the QST dashboard where controls are provided, or by clearing your browser storage for the app.

How We Use Information

We use information to:

provide, operate, and secure Q-MER.CH and QST
authenticate QST Listing Workspace inside Shopify Admin
load product information for the installed store
prepare listing drafts and export packs
save prepared listing records for the installed shop
generate downloadable CSV, listing pack, workspace pack, and review summary files

Sharing Information

We share information with service providers only where needed to operate our website, store, app, desktop workflow, downloads, support, security, billing, or legal obligations.

Service providers and third parties may include:

Shopify, to host the store, authenticate merchants, provide the Shopify Admin app platform, process Shopify App Store billing, and provide store or app functionality
hosting, database, storage, logging, and infrastructure providers used to operate QST
email and support providers used to respond to merchant requests
payment and checkout providers used for website purchases
analytics or advertising providers if enabled for the website and permitted by your cookie or privacy choices
software distribution providers used to host or deliver downloads
eBay or other marketplace APIs only if you choose to connect an optional marketplace workflow in QST Desktop
legal, regulatory, fraud-prevention, or security recipients where required to comply with law or protect rights

We do not share Shopify product data with a marketplace unless you choose to use an optional workflow that sends or exports data for that purpose.

Cookies And Similar Technologies

q-mer.ch and services used to run the website may use cookies and similar technologies to:

operate the storefront and checkout
remember preferences such as region, currency, cart, or login state
understand website performance and usage
support security, fraud prevention, and analytics
support marketing or advertising where enabled and permitted

You can control cookies through your browser settings. Blocking cookies may affect parts of the website, checkout, or app experience.

Because there is no consistent industry standard for "Do Not Track" signals, we do not alter our practices when we detect such a signal from your browser.

Legal Bases

Where UK GDPR, GDPR, or similar privacy laws apply, we process personal data under one or more of the following legal bases:

performance of a contract with you or your business
your consent
compliance with legal obligations
our legitimate interests, where those interests do not override your rights and freedoms
protection of vital interests, where applicable

Our legitimate interests include operating and securing our website and software, providing support, improving reliability, preventing misuse, maintaining records, and developing QST features.

Retention

We keep information only for as long as needed for the purposes described in this policy, including to provide QST, maintain security, troubleshoot issues, meet legal obligations, resolve disputes, and maintain business records.

When a merchant uninstalls QST Listing Workspace or requests deletion, we process the request according to Shopify's required app privacy workflow and applicable law.

Browser-local draft data remains in the merchant's browser until cleared by the merchant, by QST controls where provided, or by browser storage settings.

QST Desktop local files, exports, caches, preferences, and logs remain on the merchant's Windows device until deleted by the merchant, removed by app controls, or removed during uninstall where applicable.

International Transfers

We may process and store information in the United Kingdom and in other countries where Shopify, hosting providers, infrastructure providers, support providers, or other service providers operate.

Where required, we rely on appropriate safeguards for international transfers, such as contractual protections, platform terms, recognised adequacy decisions, or other lawful transfer mechanisms.

Security

We use reasonable technical and organisational measures to protect information processed by QST and q-mer.ch. No method of transmission, storage, software operation, or internet service is completely secure.

You are responsible for keeping your Shopify account, Windows device, marketplace accounts, passwords, recovery codes, API keys, and local files secure.

Your Choices And Rights

Depending on your location and the laws that apply, you may have rights to:

request access to personal data we hold about you
request correction of inaccurate personal data
request deletion of personal data
object to or restrict certain processing
request a portable copy of your personal data
withdraw consent where processing is based on consent
complain to a data protection authority

Merchant Choices

Merchants can:

clear browser-local QST draft data from the QST dashboard where controls are provided
disconnect optional desktop marketplace accounts inside QST Desktop
delete local files, exports, logs, and caches from their Windows device

Children's Privacy

QST and q-mer.ch are intended for business users and are not directed at children. We do not knowingly collect personal data from children.

Automated Decision-Making

We do not use QST merchant data for fully automated decision-making that produces legal or similarly significant effects.

Shopify, payment providers, marketplaces, and fraud-prevention providers may use limited automated systems to prevent fraud, enforce platform rules, process payments, or protect their services under their own policies.

Changes To This Policy

We may update this Privacy Policy from time to time to reflect changes to our practices, QST features, service providers, legal obligations, or operational requirements.

The updated version will be posted on this page with a new "Last updated" date at the bottom of this page.
