Android devices and Chrome browsers receive push notifications through a technology called Firebase Cloud Messaging (FCM). FCM expires tokens for devices that have been inactive for more than 270 days. These devices may be lost, destroyed, or put into storage and forgotten and are considered no longer reachable.

This is a cleanup exercise from Google–your expected clicks and sessions and the value you get from OneSignal will not change. In addition, you may see some benefits, including:

  • More accurate analytics: your CTR will more accurately reflect your reachable audience and the level of engagement
  • Faster delivery: removing inactive devices results in smaller audiences, and the campaign finishes delivering faster
  • Less manual work: save on time previously spent managing inactive audiences
