HisabBook notification test

Isolated test only. No customer records, Supabase login, Analytics, or message sending.

I confirm this project is on Spark and consent to register this test browser and receive generic test notifications.

Not registered.

No foreground message observed on this page load.

Test installation ID (share privately with the test operator only)

On the HTTPS test site, Download saves an exact test-target JSON file to your device; transfer it privately to the operator. On localhost, Save writes to the local ignored file. Neither sends a notification. Do not transcribe the ID from a screenshot.

This page cannot send push. Registration is not proof of notification delivery. Real phone/background/tap tests are still required.

Phone setup: open the HTTPS test site. Android Chrome: menu → Install app / Add to Home screen. iPhone (iOS 16.4+): Safari → Share → Add to Home Screen. Open the installed HisabBook Test app before enabling notifications. Localhost works only on the computer.
