Privacy Policy
Last updated: 12 November 2026
This policy explains how the Rengify Shopify app ("Rengify"), provided by Epratik Yazılım Medya Ltd. Şti. ("Epratik", "we"), collects, uses and deletes store data.
Data We Collect
Rengify only processes the store data it needs to provide the service:
- Shopify product information: product ID, handle, title, status, image URL, variant barcodes, SKUs, inventory item IDs, stock status and color option value.
- Source records: barcode, model code and name, color code, color name, hex code and sort order coming from your Nebim ERP or from a CSV/Excel file you upload.
- ERP connection details: server address, database name, user group, user name and password. The password is stored encrypted with AES-256-GCM and is never shown on any screen.
- App settings: the color table (hex, color family, pattern image, order), swatch appearance and data source settings.
- ERP pull and sync records: the time, counts and error messages of each pull and sync.
- The store session token that Shopify issues when the app is installed.
Customer Data
Rengify does not access, request or store the names, emails, phone numbers, addresses, orders or payment details of your store's customers.
How We Use Data
Data is used only to match barcodes to Shopify products, write the Rengify Renk and Rengify Model metaobjects and product metafields to your store, show color swatches on your storefront, monitor errors and support you. We do not sell your data, use it for advertising or share it with third parties other than the sub-processor listed below.
Sub-Processors
We use one sub-processor to run Rengify:
- Railway, Inc. cloud infrastructure: hosting of the application and its database.
Shopify provides the platform the app runs on and processes store data under its own privacy policy.
Storage and Security
Data is stored in an access-restricted database on Railway, Inc. cloud infrastructure. Connections are encrypted and ERP passwords are encrypted with AES-256-GCM.
Retention
- Store data is kept while the app is installed.
- ERP pull and sync records are kept for 30 days and then deleted.
- All data of your store is deleted from our database within 48 hours of the shop/redact webhook that Shopify sends after you uninstall the app. If that notice never arrives, the records are deleted 30 days after uninstalling.
Because Rengify does not store customer data, there is nothing to delete for customer data requests and customer deletion notices. To have your data deleted sooner, write to support@rengify.com.
Uninstalling the App
When you uninstall Rengify our access to your store ends immediately. Shopify deletes the app-owned Rengify Renk and Rengify Model definitions (named Rengify Color and Rengify Model when your content language is English) at uninstall. Shopify keeps their entries temporarily without a definition. The product metafields Rengify wrote in its app namespace are removed together with their definitions. Swatches stop showing on your storefront because the app block and app embed no longer render.
Your Rights
Under the GDPR and Turkey's Personal Data Protection Law No. 6698 you have the right to access your data and to ask for it to be corrected or deleted. Send your requests to support@rengify.com.
Changes
When we update this policy, the date on this page changes. We announce important changes inside the app.
