Nyuka — Privacy Policy

Last updated: September 10, 2026

Nyuka is a Shopify app, operated by Hakori, that lets shoppers ask to be notified by email when a sold-out product is back in stock. This policy explains what data the app processes and why.

1. Data we process

Merchant & store data. When you install Nyuka we store your shop domain, the Shopify access tokens needed to authenticate the app, your store name and account email, and the app settings you configure (sender name, reply-to address, email texts).

Shopper data. When a shopper submits the “Notify me” form, we store the email address they typed and the product variant they asked about. Nothing else: no name, no IP address, no Shopify customer profile. The email address is used for exactly one purpose — sending a single back-in-stock notification for that product. The merchant can access current subscriber addresses through an authenticated CSV export in Nyuka.

2. Who processes it

The merchant is the data controller; Hakori acts as processor. Data is hosted on Railway (European Union). Notification emails are delivered by Resend. Shopify provides the store data the app reads (products, inventory availability, theme templates).

3. Retention

Email addresses are erased 90 days after the notification has been sent, or 12 months after the request if the product never came back in stock. If an email bounces or is reported as spam, a cryptographic fingerprint is kept for up to three years to prevent further sends. Anonymised counts are kept for statistics. All data for a store is deleted after the app is uninstalled, following Shopify’s data redaction schedule.

4. Your rights

Shoppers can exercise their rights (access, erasure) through the merchant’s store, or by contacting us at contact@hakori.fr. Nyuka implements Shopify’s mandatory privacy webhooks: data requests, customer erasure and store erasure are handled automatically.

5. Cookies

Nyuka sets no cookies on the storefront. The button stores a small technical flag in the browser’s session storage to remember that a request was sent on the current page.
