Margin Guardrails · Last updated 27 September 2026

Margin Guardrails ("the app", "we") is a Shopify app operated by Think Launcher. It shows merchants which products lose money and how to fix them. This policy explains what store data the app uses when a merchant installs it. Questions: thinklauncher@gmail.com.

Data we access from your Shopify store

• Products and variants: titles, SKUs, prices and "Cost per item", to calculate profit per product. When you enter or upload costs in the app, we save them to "Cost per item" in your store.
• Orders from the last 30 days: only which product variant was sold, the quantity, the price paid after discounts, and whether the order was cancelled. This powers the 30-day forecast.

We do not access or store your customers' names, email addresses, phone numbers, addresses or payment details.

Data we store

• Your shop domain and the access token Shopify issues to the app.
• The cost settings you enter (payment fees, shipping, returns, target margin).
• Sales totals per product variant for the last 30 days (units sold and revenue), refreshed about every 12 hours.
• Profit alerts: product titles, prices and profit figures.
• Your Margin Guardrails plan (Free or Pro).

How we use it

Only to provide the app's features to you. We do not sell data, share it for advertising, or use it for any other purpose.

Where it is stored and who processes it

• Render hosts the app and its database in the United States. Data is encrypted in transit (HTTPS) and at rest.
• Shopify provides the store data and handles billing for the app.

How long we keep it

We keep store data while the app is installed. When you uninstall, the access token is deleted immediately, and all remaining data for your store is deleted when Shopify sends its data deletion request, 48 hours after uninstalling.

Your rights

You can ask us what data we hold about your store, or ask us to delete it, at any time: email thinklauncher@gmail.com. We respond to customer data requests passed on by Shopify; since the app stores no customer personal data, there is normally nothing to return or delete.

Changes

If this policy changes, we will update this page and the date above. Significant changes will be announced in the app.
