How do I track uninstallers? Is there a way to find out exactly about my uninstaller base?

Parvati, you can use the Uninstall dashboard in CleverTap to view the number of users uninstalling your app. https://docs.clevertap.com/docs/uninstalls-view But better to predict your users who might uninstall your app and act on engaging them while you can using our Intent Based Segmentation - https://docs.clevertap.com/docs/intent-based-segments

You can check App uninstalled from the event under Find People (Segments) . You may have to switch on Uninstall Tracking from the Settings first.
