We only read order data for orders that were written into your store via STACK'D. We do not read, synchronise, or use your store's existing customer lists or customer profiles for marketing purposes. Collected order data is deleted in line with the documented retention periods or fully removed via the Shopify shop/redact webhook (within 48 hours of app uninstall).

Mandatory Shopify privacy webhooks (GDPR webhooks)

As an official Shopify app we support the mandatory Shopify privacy webhooks. Requests are processed within the deadlines defined by Shopify:

  • customers/data_request - customer access requests are processed within 10 days. We compile the order data we hold for the customer and provide it to the shop owner.
  • customers/redact - deletion requests for an individual customer are executed within 30 days, unless a statutory retention obligation applies (e.g. German Commercial Code § 257 HGB or Fiscal Code § 147 AO).
  • shop/redact - within 48 hours of app uninstallation, all shop data not subject to retention (access tokens, product cache, configuration data) is permanently deleted.

In the scope of the Shopify integration we process personal data of the brand partner's end customers (in particular name, shipping address, order content) as independent controller for the sales transaction conducted via STACK'D. For orders we write into your store, we act as a technical interface partner. A data processing agreement under Art. 28 GDPR is available to brand partners on request.

You may request deletion of all data not subject to retention obligations at any time by email to info@stacked.clothing.
