+## Notifications
+
+The app has two notification paths:
+
+### 1. Remote push notifications
+
+On supported native builds, the app requests notification permission, obtains an Expo push token, and stores it in `user_push_tokens`.
+
+This path depends on:
+
+- A valid `EXPO_PUBLIC_EAS_PROJECT_ID`
+- A physical device
+- Notification permissions being granted
+
+Important limitation:
+
+- Android push notifications are currently not supported in Expo Go. To test Android push behavior, you need a development build or another native build type instead of Expo Go.
+
+### 2. Realtime local-notification fallback
+
+If push registration is unavailable, the app falls back to listening for new `Notes` inserts through Supabase Realtime and schedules a local notification on-device instead.
+
+This fallback can happen when:
+
+- The app is running on a simulator or emulator
+- The Expo push project ID is missing
+- Push token registration fails for another reason
