Subscribe device

​

Notification Token

• The SDK retrieves the device’s push token during subscription.
• This token is used to deliver notifications via the Expo Push Service.

​

Device Metadata

• The SDK collects hardware details such as:
  • Device manufacturer (Apple, Samsung)
  • Device model (iPhone 14, Pixel 7)
  • OS version and platform (Android or iOS)

​

Location & Localization

• To support region-aware notifications, the SDK captures:
  • Locale (en-US,fr-CA)
  • Language and country
  • City and timezone
  • Coordinates - Latitude and longitude

​
