Jeeves

Alerts from Vesa's machine.

Add to Home Screen first

iOS only delivers push to an installed web app, so subscribing from the browser tab is not possible.

Tap the Share button in Safari.
Choose Add to Home Screen.
Open Jeeves from the new icon and come back to this page.

Register this device

This asks iOS for notification permission and creates a subscription bound to this device.

Registered

Copy this, then run make push-subscribe on the Mac. It reads the clipboard, so with Universal Clipboard there is nothing to paste.

No push here

This browser has no Push API. Safari on iOS 16.4 or later, installed to the Home Screen, or any desktop Chrome, Edge or Safari.

Notification bodies are encrypted to this device.
Apple relays them without reading them.
