Device info context

Device Info Context is an entity attached to events that provides information about the Roku device. It gives information about the device model and OS, adds unique identifiers for the channel and device, includes playback settings, current device usage, locale, display properties, network status, and device features.

The context is automatically added to all tracked events by default. If you prefer not to add the context to events, you may disable it using the subject.deviceContext option during tracker initialization: = {
subject: {
deviceContext: false ' disabling device info context

Roku's ID for Advertisers (RIDA)‚Äč

RIDA is a Universally Unique Identifier (UUID) that is unique and persistent for the Roku device. It is designed to generally follow the guidelines established for the IDFA (Identifier for Advertising) that are available on other platforms such as iOS and Android. The ID is intended for Roku publishers to enable frequency capping and targeted advertising on the Roku platform.

Users can disable RIDA tracking by selecting "Limit ad tracking" in the device settings. In this case, the IsRIDADisabled property will be true and RIDA will be a temporary ID that expires after 30 days.

RIDA is tracked by the tracker by default. However, there may be cases where you may not want to track the identifier. To disable tracking RIDA, deactivate the subject.RIDATracking option during tracker initialization: = {
subject: {
RIDATracking: false ' disabling tracking RIDA
