App: Dateria Estimated Delivery (Shopify app) · Provider: GRAMSHIFT (Tokyo, Japan) · Last updated: 2026-10-15

Summary

Dateria Estimated Delivery does not collect, store or share any personal data of your customers. It does not read orders or customers. Your delivery settings are saved in your own Shopify store. Our server keeps only what it needs to connect to your store: your store's address and the access token Shopify gives the app, plus short-lived logs. Shoppers' browsers never contact our server.

What the app reads from your store

• Products, collections, tags, vendors and product types (names and IDs), with read-only access, so you can pick them in Exclude products and in Rules. The app does not change your products.
• Your store's published languages, with read-only access, so Translations shows one column for each language you sell in.
• Your store's name, address on myshopify.com, time zone, country and the countries you ship to, so dates are counted in your time zone and the preview and Rules offer your countries.
• Your app plan, from Shopify, to know whether Pro features are on.
• A signed session token that Shopify sends with every request from the admin, to check that the request really comes from your store. The app does not read the staff member's name or email.

What the app saves, and where

The app does not request any permission for orders, customers or other customer data, it has no permission to change your products or theme files, and it uses the access token only for the features described here. Your plan is checked with Shopify when you open the app and kept in memory for a few minutes, not stored.

Your storefront and your shoppers

• On a product page, your theme writes the delivery settings, the product's stock status and the country the shopper chose in your store's country selector into the page. A small script, served by Shopify as part of your theme, counts the date in the shopper's browser. The script makes no network requests and stores nothing in the shopper's browser.
• When a shopper adds the product to the cart, the date range is added to that cart line as "Estimated delivery" (you can switch this off in Design). It goes to your store's cart and order like any other line note, not to GRAMSHIFT.
• The app sets no cookies and uses no analytics, advertising or tracking. Shoppers' browsers send nothing to GRAMSHIFT.

In the Shopify admin

The app remembers in your own browser's local storage when it last asked you for a review, so it does not ask again too soon. Nothing about this is sent to our server.

Sharing

We do not sell or rent any data and do not share it with third parties, except the service providers named on this page (our server host, our email forwarding provider and Google for email), and when the law requires it.

Information GRAMSHIFT receives from Shopify

As an app provider, we see in the Shopify Partner Dashboard which stores installed the app, their plan and billing events, and the store contact details Shopify shares with app providers. We use this only to manage plans, answer support requests and meet legal obligations. Payments are processed by Shopify; we never receive card details.

Support requests

If you email us, we receive what you choose to send (for example your email address, your message and screenshots) and use it only to answer you. Email to contact@gramshift.com is forwarded by our email forwarding provider (ImprovMX) to a mailbox hosted by Google (Gmail), so those providers process support emails on our behalf.

Retention and deletion

• Removing the app: when Shopify tells us the app was removed, we delete your store's access token and session data from our server. Forty-eight hours after removal, Shopify sends a request to erase the store's data, and we delete anything that is left for your store.
• Your delivery settings are app data on the app's installation, so Shopify removes them together with the installation when the app is removed. Removing the app also removes the app embed and block at once, so your product pages no longer show the date. Dates already added to past orders stay on those orders, like the rest of the order.
• Customer data requests: the app holds no customer data, so requests that Shopify forwards for a customer's data or its erasure find nothing to return or delete.
• Support emails are kept only as long as needed to handle the request and meet legal obligations; you can ask us to delete them. Installation and billing records are kept for up to 7 years for accounting and tax purposes.

Security

All connections use HTTPS. The app's server checks the signature of every request and webhook from Shopify, runs under its own restricted system user, and keeps its database and secrets readable only by that user.

Legal basis and location

We process store information to provide the app you installed (contract) and for our legitimate interest in keeping the service secure and answering requests, and to meet legal obligations. GRAMSHIFT is based in Japan, and our server is in Japan.

Your rights

You can ask us to access, correct or delete personal information we hold about you, or object to its use, by emailing contact@gramshift.com. If you are in the EEA or the UK, you can also complain to your local data protection authority.

Changes

If the app starts to collect more data or send data anywhere else, this policy will be updated before that change is released, and the date above will change.
