Privacy policy

Who we are

Atelvar Marge (“Marge”) is a Shopify app made by Atelvar (“we”, “us”). You can reach us at [email protected]. The legal entity behind Atelvar has not yet been finalised; we will update this page when it is. We do not publish a postal address on this website.

This policy explains what Marge collects when a Shopify merchant installs it, what we do with it, and how it gets deleted. It also covers this website and the free calculator on it. Marge is not available to install yet.

What Marge can read from Shopify

Marge asks Shopify for three read only permissions: read_products, read_orders and read_inventory. It can’t change anything in your store. It doesn’t write prices, costs or stock back to Shopify.

With those permissions Marge copies the following into its own database:

• Your shop: the shop’s myshopify domain, its name and its currency.
• Products: product and option titles, SKUs, selling prices, image links, stock on hand, and Shopify’s Cost per item if you have filled it in (shown only as a suggestion).
• Orders: the order label (like #1036), the date, currency, what was sold and for how much, discounts, shipping charged, payment fees Shopify reports, refunds and restocks, and the sales channel. This is what lets Marge show what you kept on each sale.

Marge does not store your customers’ names, email addresses, phone numbers or postal addresses. It only needs the money side of each order.

What you type into Marge

Materials and what you paid for them, recipes, what you paid for bought in stock, your time and hourly rate, overheads, postage, fee rates, tax settings and any product ideas you add. This stays in Marge and is only used to work out your costs and profit.

Sign in and billing

To keep Marge connected, we store the access token Shopify gives us for your shop. These tokens expire and are refreshed by Shopify. When a shop is on a paid Marge plan, Marge asks Shopify’s Partner API which Marge plan your shop is on, using your shop’s Shopify ID. Shopify handles all payments. We never see your card or bank details.

Why we use it

• To show your costs, what you keep on each sale and each order, and which products a price rise affects.
• To keep Marge working for your shop: signing in, refreshing from Shopify, applying your plan’s product allowance, and fixing problems.

We don’t sell your data, we don’t use it for advertising, and we don’t contact your customers.

Where it’s kept

When Marge is available, it will run on Fly.io. Its database and server will sit in Fly.io’s US East (Virginia) region, so your shop’s data will be stored in the United States. Our server keeps short technical logs, which can include your shop’s domain, to help us fix errors. This website and the calculator load fonts from Google Fonts, which means Google sees your browser’s IP address when the fonts load.

The United States is not a country New Zealand has officially listed as having privacy safeguards comparable to the Privacy Act 2020. We plan to use Fly.io so the app can run. We will work on contractual safeguards with our host. Until those are in place, you should know that US law may not protect the information in a way that, overall, provides comparable safeguards to the New Zealand Privacy Act. By installing Marge you agree to that storage. This is explained here so you can decide before you install.

We don’t share your data with anyone else, except our hosting provider so the app can run, Shopify as part of how apps work, or if the law requires it.

When you uninstall

When you uninstall Marge we delete your shop’s access token straight away. About 48 hours later Shopify sends us a request to erase your shop’s data, and Marge deletes everything it holds for your shop: products, materials, recipes, orders, fee settings and your shop settings. If you’d like it deleted sooner, email [email protected] and we’ll do it.

Requests about your customers

Shopify passes on requests from your customers who want to see or erase their data. Marge supports these requests. Because it doesn’t keep customer names or contact details, there is normally nothing personal about a customer for it to hand over or erase.

Your rights

You can ask to see the data Marge holds about your shop, correct it, or have it deleted. Most of it you can already see and change inside Marge. If you’re in the EU or UK you also have rights under the GDPR, including to object or complain to your data protection authority. In New Zealand you can complain to the Privacy Commissioner. Please contact us first at [email protected] and we’ll sort it out.

If you have customers overseas

You remain in charge of your customers’ personal information (you are the controller). Marge acts as your processor for the shop and order data it holds, and only uses it to run Marge for you, as set out in these pages. We don’t use it for our own marketing, and we don’t sell it. This policy is not a formal data processing agreement. If you need a signed processor agreement for the GDPR or similar rules, email [email protected] and we’ll put one in place.

If something goes wrong

If there is a serious privacy breach we will tell you, and we will tell the Privacy Commissioner and Shopify when the law or our agreements require it.

This website and the calculator

The free calculator works in your browser. What you type into it isn’t sent to us or saved. This website doesn’t use analytics or advertising cookies. If you email us, we will use your email address and the content of your message to reply and to keep a record of the request.

If you ask to join the Marge waitlist, we will keep your email address so we can tell you when Marge is available, and we will delete it if you ask us to, or after we have told you it is available and no longer need it for that purpose.

Changes

If we change how Marge handles data, we’ll update this page and change the date at the bottom. If it’s a big change, we’ll tell you inside Marge first.
