Privacy Policy
Last updated: October 23, 2026
884 works, operated by Yuki Hayashi ("we"), explains how the Shopify app "見たまま名入れ: Engraving Preview" (the "App") handles information.
1. Scope
This policy covers Shopify stores that install the App ("Merchants") and the customers who buy personalized products from those stores ("Customers").
2. Information we collect
| Information | Source | Examples |
|---|---|---|
| Store information | Shopify | Store domain, App plan, access token |
| Staff identifiers | Shopify admin | The ID of the staff member who saved a template or marked an order as produced (we do not collect names or emails) |
| Product information | Shopify | Name, variants, and image URLs of products set up for personalization |
| Personalization content | Customer input | Engraving text, font, orientation |
| Order information | Shopify (order webhooks) | Order number, order date, order lines that include personalization (product, quantity, personalization content) |
| Files uploaded by Merchants | Merchant | Font files |
| Technical information | Network | IP address (used only for short-term rate limiting and not stored), error logs |
We do not collect Customers' names, email addresses, phone numbers, postal addresses, or payment information. However, engraving text may contain the name of the Customer or the gift recipient, so we treat engraving text as personal data.
3. How we use information
- To show a preview of the personalization on the product page
- To create production files (SVG, PDF, preview image) for ordered personalizations and provide them to the Merchant
- To show the list and details of personalized orders in the Merchant's admin
- To manage the Merchant's plan and usage
- To prevent abuse and investigate problems
We do not use information for any other purpose. We do not use it for advertising or marketing, and we do not sell data.
4. Sharing and processors
We do not share information with third parties without consent, except as required by law. We use the following providers to run the App, and information is stored and processed within their services.
| Provider | Purpose |
|---|---|
| Shopify Inc. | App distribution, authentication, billing, order delivery |
| Cloudflare, Inc. | App hosting (Workers), database (D1), file storage (R2) |
Their servers may be located outside Japan.
5. Retention
| Information | Retention |
|---|---|
| Personalization drafts not added to cart | 7 days from creation |
| Produced personalized orders and production files | 180 days after being marked as produced |
| Cancelled personalized orders | 180 days after cancellation |
| Personalized orders not yet produced | 365 days from the order |
| Records of data requests | 90 days |
| All store information and files | Deleted when we receive Shopify's deletion request (shop/redact) after the App is uninstalled |
Expired information is deleted by a daily job.
6. Customers' rights (access and deletion)
When a Customer asks a Merchant to access or delete their data, the request reaches us through Shopify.
- Access requests (customers/data_request): we let the Merchant download the personalization content of the relevant orders as a CSV from the App's admin
- Deletion requests (customers/redact): we delete the personalization content and production files of the relevant orders
7. Security
- All traffic is encrypted with HTTPS. Stored data is encrypted at rest by our providers' services
- Production files are kept in private storage and can only be downloaded from the Merchant's admin through time-limited URLs
- Data is separated by store so that one store cannot access another store's information
8. Changes
We will announce changes to this policy on this page. Important changes will also be shown in the App's admin.
