Privacy Policy

Last updated: October 21, 2026

WarrantyKit is a Shopify app that lets a merchant register their products to the customers who bought them and manage warranty claims against the merchant's own manufacturer warranty. This policy explains what personal data the app processes, why, and how it is protected.

Our role. For the personal data of a store's customers, the merchant (the Shopify store that installs WarrantyKit) is the data controller. WarrantyKit acts as a data processor on that merchant's behalf, processing customer data only to provide the app's functionality to that merchant. This policy also describes how we handle the merchant's own account data, for which NerdLabs is the controller.

1. What We Process

1.1 Merchant / Store Data

The store's myshopify.com domain, an expiring Shopify access token, the subscription plan tier, and the merchant's warranty policies and product assignments.

1.2 Customer (Buyer) Personal Data

From the registrations phase on: email address; name; shipping address (for order-sourced registrations); the Shopify customer and order identifiers when the purchase was made on Shopify; product, variant, SKU and serial number; purchase date and retailer; and any notes the merchant adds.

1.3 Warranty-Claim Data

From the claims phase on: the claim details and the merchant's decision, and any evidence the buyer uploads (photos, video, receipts).

1.4 Store Owner's Email

The email address on the store owner's Shopify account (as set in Shopify — not the store's public contact email), the store's admin language, and whether it is a Shopify development store. It is used only to email the store owner: account alerts, a one-time welcome note on upgrading to a paid plan, and a one-time note after uninstalling asking what we could improve. It is never a customer's email.

1.5 Support Messages

If you message us from inside the app (including a free setup or customization request), we store your messages, your shop domain, the reply-to email address and name you provide or that Shopify lists for your store, and your admin language — used only to answer you and to email you when we reply.

1.6 Error Reports

If a page of the app in your Shopify admin hits a technical error, your browser sends us the error message and stack trace, the page address (without its query string), the browser type, and your shop domain, so we can find and fix the bug. Our support service on our DigitalOcean server stores the report and, through Mailgun, emails an alert with the error text and stack trace, page address and shop domain to our team's mailbox, which Google hosts. When Shopify's shop/redact request arrives, your shop domain in the stored reports is replaced with an anonymous identifier and the page address and browser type are removed. That does not cover the alert emails: we keep them while we need them to fix the bug and delete them on request.

We process the minimum data needed to provide the app's value and use it only for the purposes described here, including customer support (in-app support messages and free setup and customization help). We do not sell personal data, and we do not use it for advertising or for automated decisions with legal or significant effects — warranty-claim decisions are made by the merchant.

3. How We Protect It

4. How Long We Keep It

5. Who We Share It With

We use a small number of sub-processors, only as needed to run the service:

We do not share personal data with anyone else, and we never sell it.

6. Data Subject Rights (Shopify Privacy Webhooks / GDPR)

Because the merchant is the controller of their customers' data, a buyer who wants to access or delete their data should contact the merchant they bought from. WarrantyKit implements Shopify's mandatory privacy webhooks in full:

These support the merchant's obligations under the GDPR, the CCPA/CPRA and similar laws. Merchants agree to WarrantyKit's terms and this policy when they install the app.

7. Changes

We will update this page when our practices change and revise the date at the top.
