Privacy Policy
Last updated: October 26, 2026
Steady Shelf ("the App") is a Shopify application that sends back-in-stock email notifications on behalf of the store that installs it ("the Merchant"). This policy describes what data the App processes and why.
Data the App stores
- Subscriber email addresses — provided by shoppers who ask to be notified when a product returns to stock, together with the product/variant they subscribed to and their notification status.
- Send logs — for each notification: recipient, time, delivery status, and the sending provider's reference or error message.
- Store configuration — the Merchant's sending preferences and, if the Merchant enables the optional Klaviyo mode, their Klaviyo API key (stored encrypted).
- Inventory state — product availability levels used to detect restocks.
The App does not store shopper names, addresses, payment details, or order histories.
How data is used
Data is used only to operate the notification service: detecting restocks, sending notification emails, keeping the delivery log the Merchant can review and export, and preventing further email to addresses that bounced, complained, or unsubscribed.
Service providers
The App runs on Cloudflare (hosting and database). Notification email is delivered through Resend from the App's verified sending domain. In the optional Klaviyo mode, sending happens through the Merchant's own Klaviyo account instead. No data is sold or shared for advertising.
Unsubscribe and suppression
Every notification email contains an unsubscribe link. Unsubscribing, a hard bounce, or a spam complaint adds the address to a suppression list so it is not emailed again.
Data requests and deletion
The App honours Shopify's mandatory privacy webhooks (customer data request, customer redact, shop redact). When a Merchant uninstalls the App, store data is deleted in accordance with the shop-redact process. Merchants and shoppers may also contact us at northdeskline@gmail.com with any privacy request.
