Privacy policy
Last updated 13 November 2026
Margewise is a profit-reporting app for Shopify stores, operated by Flexi Muscles LLC ("we", "us"). This policy explains what data Margewise collects when a merchant installs it, why, where it is kept and how to have it deleted. Questions go to support@margewise.io.
Who this covers
Merchants who install Margewise, and the merchants' customers whose orders pass through it. For customer data, the merchant is the controller and we act as their processor: we use it only to produce the merchant's reports.
What we collect
- Store details from Shopify: store name, domain, currency, time zone and country.
- Orders: order number and date, line items, quantities, prices, discounts, shipping charged, tax, refunds, payment method and payment fees, and the shipping country.
- Customers: only Shopify's internal customer number for each order, so we can tell new customers from returning ones. We do not store customer names, email addresses, phone numbers or street addresses.
- Products: SKUs, titles and the unit cost recorded in Shopify.
- Advertising data from ad accounts the merchant connects (such as Meta, Google, TikTok, Pinterest and Snapchat): daily spend and conversion value per campaign. We read this data only; we never change ads.
- Settings the merchant enters: costs, fee rules, courier rates, fixed expenses and uploaded files such as courier invoices.
- Account contact: the email address the merchant uses to contact us or to receive reports.
How we use it
Only to calculate and show the merchant's profit reports, send reports the merchant asks for, provide support and keep the service secure. We do not sell data, use it for advertising, or combine one merchant's data with another's.
Where it is stored and who processes it
- Supabase (database), hosted in Frankfurt, Germany.
- Vercel (application hosting).
- Shopify and the advertising platforms the merchant connects, as the sources of the data.
Data is encrypted in transit. Access is limited to the people who run Margewise and only for support or maintenance.
How long we keep it
For as long as Margewise is installed. When a merchant uninstalls the app, Shopify notifies us and we delete that store's data within 48 hours of Shopify's deletion request. Merchants can ask us to delete their data at any time by emailing support@margewise.io.
Requests from shoppers
When a shopper asks a merchant for their data, or asks for it to be erased, Shopify forwards the request to us. Because we hold only an order's customer number and no personal details, we either report what we hold or delete it, and confirm to the merchant.
Your rights
Depending on where you live (for example under the GDPR, the UK GDPR, South Africa's POPIA or the UAE's data protection law), you may have the right to access, correct, delete or move your data and to object to its processing. Email support@margewise.io and we will respond within 30 days. You may also complain to your local data protection authority.
Changes
We will update this page when our practices change, and tell installed merchants about material changes.
