Doorday: Delivery Date ETA ("the App") is developed by Digital Cartel ("we", "us", "our"). This policy explains what data the App handles, what we store, and your rights.
No shopper personal data is processed by the App. On your storefront the App makes no requests to our servers at all. We store a small amount of store-level information so that billing works, and we delete it when you uninstall.
Doorday is a theme app extension. The delivery date block is rendered by your theme, using settings you save in the theme editor, and the dates are worked out in the shopper's browser from your store's clock and those settings.
On the paid plan, if you switch on "Add the estimate to the cart line", the App adds a visible line item property (named by you, "Estimated delivery" by default) holding the estimated delivery dates to the product the shopper adds. That property is stored by your store on the cart and order, in your own admin, and it is never sent to us.
Only while you are editing your theme, and never on the live storefront, the App asks our server whether your store is on the paid plan. That request carries your myshopify domain and the app handle, and nothing else. No shopper is involved, and the response is a single true or false value used to show you the correct upgrade note.
Billing runs through Shopify's own subscription system. We never see or handle card details. To keep your plan status correct we store, per installed store:
That is the complete list. It is store-level configuration, not personal data about you or your shoppers.
The three items listed above are held in an encrypted key value store operated by our hosting provider, reachable only by our server over TLS with a private credential. Your settings (cutoff, processing and shipping days, holidays, messages, rules, zones, colours) live entirely in Shopify's own theme settings and never reach us.
When you uninstall the App, Shopify sends us an uninstall notification and we delete your stored domain, access token and plan status. Shopify removes the theme extension automatically. Your theme settings may remain in your theme until you remove the block yourself.
The App integrates with no third-party analytics platforms or advertising networks. Our server runs on Vercel, which hosts the endpoints described above. Billing is handled entirely by Shopify.
You can:
No shopper personal data is processed, stored or transmitted by the App, so no consent banner, data subject request handling or data processing agreement is required in relation to Doorday. We answer Shopify's mandatory data request, customer redaction and shop redaction webhooks, and because we hold no customer records those requests return nothing to redact.
We may update this policy occasionally. Changes will be reflected on this page with an updated date. Continued use of the App after changes constitutes acceptance.
