ARCETRI Privacy Policy

Last updated: September 7, 2026

ARCETRI (James Agustin Gil Narro, doing business as ARCETRI) develops Shopify apps. This policy has a separate, self-contained section for each app below. Contact: support@arcetri.app.

CouponGuard

Who we are

CouponGuard is developed by James Agustin Gil Narro, doing business as ARCETRI ("ARCETRI", "we", "us"). Contact: support@arcetri.app.

What CouponGuard does

CouponGuard is a Shopify app that lets a merchant restrict a discount code so it only works for shoppers who arrive through a specific, merchant-generated link (a "protected campaign link" — typically shared with a creator, influencer, or affiliate). Shoppers who use the same code without going through that link do not receive the discount.

Data we collect from your store

When you install CouponGuard, we access and store the following, and nothing else:

• Your store's domain (e.g. yourstore.myshopify.com).
• An OAuth access token and refresh token, issued by Shopify, that let CouponGuard call Shopify's Admin API on your behalf (to create protected discounts and register the app's operational webhooks). These are never visible to anyone outside CouponGuard's servers.
• A Shopify Storefront API token, provisioned automatically at install, used only to authorize shopping carts that arrive through a protected link.
• The discount codes you choose to protect, and a randomly generated security value CouponGuard creates for each one (used internally to check cart authorization — it is never shown to you, your shoppers, or anyone else).
• The campaigns you create (names and labels you type in, e.g. a creator's name) and the links CouponGuard generates for them.
• Basic usage counters for your own dashboard (e.g. how many protected links were clicked).

Data we do NOT collect

CouponGuard does not collect, store, or process any personal information about your shoppers. We do not see or store shopper names, email addresses, physical addresses, phone numbers, IP addresses, browsing behavior, or order history. CouponGuard's authorization mechanism works entirely by tagging a shopping cart, not by identifying a person — a protected link authorizes whichever cart requests it, without knowing or needing to know who is behind that cart.

Because we hold no shopper personal data, there is no shopper data to export or delete under GDPR/CCPA-style requests — see "Your rights" below.

How we use your store's data

Solely to operate the product: creating and managing the discounts you protect, generating and verifying campaign links, authorizing shopper carts, and running your subscription billing through Shopify's Billing API. We do not sell your data, share it with third parties for marketing, or use it to train any model.

Data retention and deletion

Your store's data (as listed above) is retained for as long as CouponGuard is installed on your store. When you uninstall CouponGuard, Shopify notifies us via its mandatory shop/redact compliance webhook — sent automatically by Shopify approximately 48 hours after uninstall — and on receiving it we permanently delete all of your store's data, including access tokens, protected discount records, and campaigns.

Your rights

Because CouponGuard stores no personal data about shoppers, there is no shopper-level data subject request to fulfill. If you are the merchant and want your own store's data deleted immediately rather than waiting for the uninstall-triggered process above, contact us at support@arcetri.app and we will remove it as soon as reasonably possible.

Known limitation, disclosed plainly

Once a shopper's cart is authorized through a protected link, they are redirected to a real Shopify checkout URL with the discount applied. Like any checkout link on any e-commerce platform, that specific URL can be forwarded by the shopper who received it. CouponGuard's guarantee is that the underlying discount code itself does not work outside of an authorized protected link — it does not, and cannot, prevent a shopper from sharing a checkout URL they were already given.

Delivery Promise

Who we are

Delivery Promise is developed by James Agustin Gil Narro, doing business as ARCETRI ("ARCETRI", "we", "us"). Contact: support@arcetri.app.

What Delivery Promise does

Delivery Promise shows shoppers an estimated delivery date and a dispatch countdown on a merchant's product pages, based on settings the merchant enters (such as processing time, shipping time, order cutoffs, holiday dates, and optional rules for specific countries, products, or collections).

No customer or order data

Delivery Promise does not request Shopify Admin API access to customer, order, checkout, or product data, and it does not store any customer or order information.

Data we collect and store

• The delivery settings you enter (processing time, transit time, cutoffs, holiday dates, override rules, and display wording) are stored as configuration attached to your own store. This is merchant-entered shipping configuration — not a customer record, an order record, or personal data of any kind.
• A secure connection record that lets the app stay installed and make authorized requests to Shopify on your behalf. This contains no customer or order information.

How the storefront display works

The delivery-estimate text shown on your product pages is generated entirely in the shopper's own browser. It does not send any information to Delivery Promise's servers — it reads your settings and basic, publicly visible product details (such as tags and collections) and your store's market/country context directly through your storefront theme, and calculates the estimate locally. No shopper data is transmitted to, or stored by, Delivery Promise as a result of a storefront page view.

Billing

Subscription billing is handled entirely by Shopify through the Shopify Billing API. Delivery Promise does not collect, process, or store payment details, card numbers, or billing addresses.

Data retention and deletion

Your connection record is deleted as soon as you uninstall Delivery Promise. Your delivery settings remain attached to your own store — they are your data — unless you delete them yourself or reinstall and choose to restore default settings.

Your rights

Because Delivery Promise holds no customer or order data, there is no shopper-level data subject request to fulfill. Delivery Promise implements Shopify's mandatory data-protection notifications for customer data requests and deletion; since we hold no customer or order data, there is nothing to return or delete when one is received. If you are the merchant and want help removing your Delivery Promise settings from your store, contact support@arcetri.app.

Changes to this policy

We may update this policy from time to time. Material changes will be posted here with an updated "Last updated" date above. If you have questions about the current policy, contact support@arcetri.app.
