How are uninstalls tracked?

Leanplum runs a job every 24 hours to check if a user’s push token is still valid. Based on the response we get back from Apple or Google, we can assume that the user either still has the app installed or has deleted the app from their phone.

If we get a failure response upon attempting to validate the token, we will discard the user's, now expired, push token -- in compliance with Apple and Google policy.

See enabling uninstall tracking if you would like to activate this out of the box feature in your app.
