Simple Push Notifications: privacy notice

Last updated: 19 October 2026.

This app lets stores send announcements to browsers that explicitly subscribe. The store chooses the messages and their destination links.

What we store

For subscribers, we store the browser push endpoint, encryption keys, store domain, and subscription date. These online identifiers allow delivery to a browser. We do not request Shopify customer records, email addresses, orders, or browsing history, and we do not track notification opens or clicks.

For merchants, we store Shopify authentication sessions, per-store signing keys, announcement content, delivery jobs, and aggregate acceptance or failure results. Session records can contain the account details Shopify supplies for authentication.

Why and where

We use this data to provide the notification service, manage subscriptions, prevent duplicate submissions, and troubleshoot failures. The app is hosted on Railway. Notifications pass through the browser provider’s push service, such as Google, Mozilla, Microsoft, or Apple; those providers process data under their own terms.

Your choices and retention

Subscribe only if you want browser announcements. You can unsubscribe on the store’s signup page or revoke notification permission in your browser. Unsubscribing through the signup page deletes the subscription record. Expired endpoints are removed when detected during a send. Revoking browser permission alone may leave the server record until it expires or is deleted.

Store data, including subscriptions, announcements, delivery jobs, and signing keys, is deleted when the app is uninstalled and on Shopify’s shop-redaction request. While installed, announcement history is kept to provide service records. We do not sell subscriber data or use it for advertising.

Up to three rotating database snapshots are stored on the same Railway volume. Deleted records may remain in these snapshots until they rotate out; old snapshots are cleaned up during startup and daily snapshot runs. These snapshots provide recovery from accidental database changes, not independent offsite backup.

For questions, consent withdrawal, or access/deletion requests, contact the store where you subscribed or email our service contact. Browser subscriptions are not linked to Shopify customer accounts, so the browser endpoint may be needed to locate a subscription. Do not send passwords or API secrets.
