Green13 Back in Stock — a Shopify app by Green13 srl. Last updated: 2 October 2026.
The merchant who installs the app on their Shopify store is the data controller for their customers' data. Green13 srl processes that data on the merchant's behalf, as a data processor, only to provide the app. Contact: info@green13.agency.
When a shopper asks to be notified about a sold-out product, the app stores:
| Email address | The address the shopper enters to be notified. |
|---|---|
| Product | Product and variant identifiers, title, handle and image link, to know what to notify about. |
| Language | The storefront language at sign-up, so the message is written in that language. |
| IP address | Used only to limit repeated sign-ups (anti-abuse). |
| Delivery status | Whether the alert was sent, when, and the message id or the error returned by the merchant's email server. |
The app does not collect names, phone numbers, addresses, payment details or order history.
The Shopify authentication session, the app settings, the store name, contact email and domain (used as the sender name, reply-to address and product link of the alerts), and the settings of the merchant's own email (SMTP) server: host, port, username, sender address and name, and the password, which is stored encrypted (AES-256-GCM) and is never shown again, not even to the merchant.
Alert emails are sent through the merchant's own email server, with the SMTP settings the merchant enters in the app. They do not pass through any email-sending service chosen by Green13: the recipient address and the message go from the app directly to the merchant's email provider, which delivers them under the merchant's own terms.
| Aruba S.p.A. (Italy) | Hosts the app and its database (servers in Italy, European Union). |
|---|
Green13 uses no other provider, and the data is not transferred outside the European Union. Shopify, which runs the merchant's store, and the merchant's own email provider, which delivers the alerts, work for the merchant under the merchant's own agreements with them.
| Alert waiting for restock | Kept until the product is back in stock and the alert is sent, or until the merchant uninstalls the app. |
|---|---|
| Alert sent or failed | Deleted automatically 90 days later. |
| Alert never sent | Deleted automatically 12 months after sign-up. |
| After uninstall | All data of the store is deleted when Shopify sends the shop redaction request (48 hours after uninstall). |
Shoppers can ask the merchant to access or erase their data. When the merchant forwards the request through Shopify, the app deletes every sign-up linked to that email address (customer redaction), or provides the stored records (customer data request). The merchant can also delete every sign-up of an email address at any time from the app (Alerts → Remove a customer's data). Shoppers may also write to info@green13.agency. In the EU you can lodge a complaint with your data protection authority.
If the data the app collects changes, this page will be updated before the change is released, and the date above will change.
