How Seamwise Size Chart & Guide handles data for the Shopify stores that install it.

Effective date: 26 October 2026

In short: Seamwise stores only the configuration a merchant creates in the app (size charts, display rules and settings) plus what is needed to connect to the store. It does not collect, store or process personal data about your customers or storefront visitors.

Who we are

Seamwise Size Chart & Guide (“the app”, “we”, “us”) is provided by Approtic Solution Private Limited, Hyderabad, Telangana, India. This policy explains what information the app accesses and stores when a merchant (“you”) installs it on a Shopify store, and how that information is used. Contact: abhinay@approtic.in.

Shopify permissions the app requests

Permission	Why it is needed
`read_products`	To read product attributes such as product type, vendor, tags and collections so the app can match a size chart to the right products and let you test which chart a product will show.
`read_locales`	To read which languages your store has enabled so charts can be shown in the matching language.

The app does not request access to orders, customers, checkouts or payments, and it does not modify your products.

Information we store

The app stores the following in a Cloudflare D1 database operated for the app:

Store identifiers: your shop’s myshopify.com domain, the store’s primary language, install and uninstall dates.
Access credentials: the access token Shopify issues to the app when it is installed, with its granted scopes and expiry, so the app can call the Shopify Admin API on your behalf.
App configuration you create: size charts (titles, size tables, measurement units, optional image links and translations), the rules that decide which products show which chart, and your display settings.
Plan status: which plan your store is on, as reported by Shopify’s Billing API. Payments are handled by Shopify; we never receive card or bank details.
Operational records: summaries of CSV/paste imports (counts and error messages), a log of when charts were published to your theme, and the IDs of webhooks already processed (to avoid handling the same event twice).

We do not store names, email addresses, phone numbers, postal addresses, order history or any other personal data about your customers.

How your storefront uses the app

When you publish, the app writes your charts to app-data metafields in your own Shopify store. Your theme then displays them through the app’s theme app extension, rendered by Shopify. The storefront script makes no network requests to our servers and does not read personal information about shoppers. The only thing it saves is a shopper’s preferred measurement unit (for example cm or in), kept in that shopper’s own browser (local storage key sc-unit); it is never sent to us.

How we use information

To provide the app’s features: building, translating, matching and publishing size charts to your store.
To check your plan and unlock the features included in it.
To respond to support requests you send us.

We do not sell or rent data, we do not use it for advertising, and the app contains no third-party analytics or tracking.

Service providers

Shopify provides the platform, authentication, billing and the storefront where charts are displayed.
Cloudflare hosts the app (Workers) and its database (D1). Like any web host, Cloudflare processes technical request data such as IP addresses and request logs in order to serve and secure the app.

Uninstalling and data deletion

When you uninstall (Shopify’s app/uninstalled webhook), the app immediately deletes your store’s access token and marks the store as uninstalled. Your charts are kept for a short period so that a quick reinstall can restore them.
Shopify then sends a shop/redact request (48 hours after uninstall). The app deletes every record it holds for your store: charts, tables, translations, rules, settings, import and publish records, processed-webhook IDs, sessions and the store record itself.
Customer data requests (customers/data_request and customers/redact) are verified and acknowledged. Because the app stores no customer data, there is nothing to export or delete for an individual customer.

Theme blocks are removed from your theme by Shopify when the app is uninstalled. You can delete individual charts in the app at any time, or email abhinay@approtic.in to ask us to delete your store’s data sooner.

Security

Webhooks are verified using Shopify’s HMAC signature before they are processed, all traffic is served over HTTPS, and every database read and write is scoped to the authenticated store.

Your choices and rights

You can review and change everything the app stores about your store from inside the app. Depending on where you are located, you may have rights to access, correct or delete personal data or to object to its processing. To make a request, email abhinay@approtic.in; we will respond as required by the law that applies to you.

Children

The app is a business tool for Shopify merchants and is not directed at children.

Changes to this policy

If we change how the app handles data, we will update this page and its effective date.
