This page covers the migration scanner and the migration plan request form on studio.mufatech.com, the Store Diagnosis and Mufatech Clearance apps for Shopify, and the Store Lens browser extension. Theme support requests are handled as described in each theme's support policy.

What the scanner collects

When you scan a store, we request public pages and public API endpoints from that store, the same data any visitor's browser can load. We store the resulting report for 24 hours so repeat scans load instantly, and we count scans per IP address for one hour to prevent abuse. We do not store your IP address with the report.

We also keep a record of what each scan found about the store itself, such as its product count, platform and detected plugins, so we can publish aggregate statistics about online stores. This record contains no information about the person who ran the scan. When a scan runs, we receive a notification with the scanned store and the visitor's country, which is derived from the connection and not stored with the record.

What the plan request form collects

• Your email address, and your name if you give it.
• The store address, the revenue range and timeline you choose, and your message.
• A copy of the latest scan report for that store.

We use this only to reply to your request and prepare a migration plan. We do not sell it, and we do not add you to a newsletter.

Store Diagnosis app for Shopify

When a store installs Store Diagnosis, the app reads its products, costs, stock levels, and orders with their discounts and refunds, and turns them into the report the merchant sees. It cannot change anything in the store.

• It never reads or stores a customer's name, email address, postal address or phone number. It does not read who placed an order at all: orders are synced without any customer field.
• The weekly report email goes to the store's contact email held by Shopify. The merchant can turn it off in the app's settings or from any of those emails.
• Product news from Mufatech is sent only to merchants who tick the box for it in the app's settings; the box is unticked by default. We keep the address they choose, the date, and the words they agreed to, as the record of that consent. Every message has a one-click unsubscribe link, and unticking the box works too.

The app's data is stored on our own server with Hetzner in Germany, with daily database backups on Cloudflare R2. Emails are sent through Postmark. When a store uninstalls the app, everything held about it, including any product news consent, is deleted when Shopify asks us to, 48 hours later.

Using the app is governed by its terms of service. For the store data it reads, the merchant is the controller and we are the processor, under the data processing addendum.

Mufatech Clearance app for Shopify

When a store installs Mufatech Clearance, the app reads its products, prices, compare-at prices, costs, stock levels, markets and orders with their discounts and refunds, to find stock that is not selling and to help the merchant clear it. Unlike Store Diagnosis, it also writes to the store, but only what the merchant sets up and confirms in the app:

• variant prices and compare-at prices, and prices in market price lists;
• whether a product is published on the online store, when the merchant puts seasonal stock away until its season;
• automatic discounts, when the merchant offers stuck stock as a gift or keeps discount codes off clearance prices;
• collections and product tags the merchant sets up in the app, a draft order for a B2B lot when the merchant allows it, and app metafields that mark clearance items and items not to reorder.

The app keeps a record of every price it changes, and a daily price and stock history per variant for up to 400 days while it is installed, so it can restore prices exactly and work out the lowest price of the last 30 days.

• It never reads or stores a customer's name, email address, postal address or phone number, and it does not read who placed an order.
• The price-drop wish list stores only how many shoppers wait at each price for each product. If a shopper leaves contact details, they go to the merchant's own customer accounts or email tool, never to us, and the app never emails shoppers itself.
• For staff who open the app, it keeps Shopify's user ID only, never a name or an email address.

The app's data is stored on our own server with Hetzner in Germany, with daily database backups on Cloudflare R2. When a store uninstalls the app, everything Clearance holds about it is deleted when Shopify asks us to, 48 hours later. If Store Diagnosis is still installed on the same store, the product, stock and order data both apps read is kept for it until it is uninstalled too.

Using the app is governed by its terms of service. For the store data it reads, the merchant is the controller and we are the processor, under its data processing addendum.

Store Lens browser extension

Store Lens reads the page you have open and that store's own public data, in your browser. It keeps no history of the stores you look at, sets no cookies and has no account.

• With the studio lookup on (the default), the extension sends this site the store's address, the name and version of its theme and, for a renamed Shopify theme, the file names of its scripts and stylesheets, so we can answer with the theme's release notes and the store's real-user speed from Google's Chrome UX Report. Turn the lookup off in the extension's settings and nothing leaves your browser.
• We record each lookup: the store, what was found, the country the request came from, the browser's language and the extension's version. Your address is not stored; it is replaced by a key that changes every day, which lets us count how many people use the extension and nothing more. The public answer for a store is cached for 12 hours. These records live on our own server.
• The contact form in the extension sends your name if you give it, your email address and your message, with the store you were looking at if you leave that box ticked. We use it only to answer you and keep it for up to 24 months after our last contact.

Site analytics

We count page views with Cloudflare Web Analytics. It does not use cookies, does not fingerprint visitors and does not collect personal data; we see totals such as pages visited, referring sites, countries and page speed.

Affiliate links to Shopify

Some links to Shopify on this site are affiliate links, marked as such next to the link. They go through impact.com, which runs Shopify's affiliate program, and record that the visit came from us so that we can be paid a referral fee if you open a paid store. We see only totals, such as clicks and paid stores per page, never who you are; impact.com and Shopify handle the click under their own privacy policies. Every other link to Shopify on this site is a plain link.

Where it is stored

Everything is stored on Cloudflare, which hosts this site. Cloudflare Turnstile checks that a scan comes from a person; it is used instead of a tracking CAPTCHA.

How long we keep it

Scan reports expire after 24 hours. Plan requests are kept for up to 24 months after our last contact, or until you ask us to delete them.
