Push Diagnostics
Run this on the device you expect to receive alerts on (on iPhone, open it from the Home Screen app, not Safari). It confirms which service worker is active and whether web push is set up — it never sends a notification and never shows your subscription endpoint or keys.
This page only reports this device's local PWA/push state. It does not show other users' devices or server subscription endpoints.
Service Worker

- Unknown

The shortened value is a one-way SHA-256 hash for this device only. The raw subscription endpoint, p256dh key, auth secret, and full push subscription are never displayed.
Actions
Updating asks the browser to fetch the newest service worker; reloading lets it take control. Your subscription is left intact.
