Privacy Policy

Last updated 22 June 2026

MarginGuard (“we”, “us”) provides a Shopify app and related tools that alert merchants when a tariff or duty rate change pushes one of their products below their target margin. This policy explains what data we handle and why. We keep it deliberately small: MarginGuard is advisory and reads more than it stores.

What we collect

What we do NOT collect

MarginGuard does not access, store, or process your customers’ personal data — no customer names, addresses, emails, or order details. We request only the read_products and read_inventory scopes. We never edit your catalog or prices.

How we use it

Sharing & subprocessors

We do not sell your data. We use a small set of infrastructure providers strictly to run the service: Vercel (hosting), Neon (database), Shopify (the platform and billing), the USITC HTS API (public tariff data lookups), and Resend (sending alert emails). Each processes data only to provide its function.

Retention & deletion

We keep your catalog and exposure data only while the app is installed. When you uninstall, Shopify notifies us and we delete your store’s data; we also honor Shopify’s mandatory shop/redact request (sent ~48 hours after uninstall). You can request deletion at any time by emailing us.

Your rights

You may request access to, correction of, or deletion of your data, and you may withdraw consent by uninstalling the app. We respond to Shopify’s GDPR/CCPA compliance webhooks (customers/data_request, customers/redact, shop/redact) as required.

Advisory disclaimer

MarginGuard provides estimates for informational purposes, combining public tariff data with your inputs. It is not customs, legal, or tax advice; verify rates with your customs broker before repricing.
