StoreFixKit Price Calculator · Last updated 2026-10-30

This policy explains what the app accesses and stores when installed on your Shopify store.

What the app does

StoreFixKit Price Calculator lets a merchant configure size-based pricing on products. Shoppers enter dimensions on the product page, and Shopify Functions recalculate and validate the price at checkout.

Data and permissions we use

• Products and product metafields — to read and write calculator settings selected by the merchant in the price_calc namespace.
• Cart transforms and checkout validations — to recalculate the configured price and reject missing, invalid, or out-of-range dimensions.
• Theme app extension — the merchant adds the calculator as an app block. The app does not read or modify theme files.

Data we store

Calculator configuration, including pricing method, customer input unit, product-price basis, size limits, and minimum price, is stored in the merchant's own Shopify product metafields. The app stores no customer personal information. Shopper dimension inputs remain as line-item properties managed by Shopify; the app does not copy or retain them externally.

Our app server stores the shop domain and Shopify OAuth session records needed to authenticate the app. These include access and refresh tokens and, when Shopify supplies them for an online merchant session, the merchant or staff user ID, name, email, locale and account flags. These are merchant account records, not shopper records.

Data we do not collect

No customer names, emails, addresses, payment details, browsing history, analytics profiles, or advertising identifiers are collected by the app.

Third parties

Shopify runs the storefront and checkout extensions and processes subscriptions through Shopify App Pricing. We operate a separate hosted app server for installation, configuration and authentication. Operational server logs can include shop identifiers, request paths, status codes and timing. We do not use customer data for advertising or sell it. Contacting support by email sends the information you choose to include through the email service.

GDPR and privacy requests

The app authenticates Shopify's mandatory customer data request, customer deletion, and shop deletion webhooks. Because the app retains no shopper personal data, there is no external shopper record to return or erase. Merchant session records are retained while needed to provide the installed app and deleted from the active app database after a verified uninstall or shop-redaction webhook. Shopify controls the lifecycle of data held in its own platform. For access or deletion requests concerning merchant account records, contact support below.
