# Opted Out Users

<Info>
  Optional step for data tracking.
</Info>

MoEngage provides you behavioral data only for the users who opt-in for push notifications. If you are trying to optimize the opt-in funnel, and check the exact stats on how many users have agreed/blocked to subscribing push notifications, you will have to track it as part of your existing analytics solution.

To achieve this, we have exposed opt-in callback interaction events that can be listened to so that you can track them using your own analytics flow.
