Re-attribution window explained

At a glance: During the re-attribution window, reinstalls are not attributed as new installs.

Re-attribution window

The re-attribution window is a time window starting from the time of the first install during which reinstalls are not attributed as new installs.

These reinstalls are not counted and do not generate new install postbacks unless they originate from a retargeting campaign.

Setting the re-attribution window

The re-attribution window:

  • is set in the App Settings page
  • default value is 90 days (3 months)
  • has a  range of 1-24 months 

When you change the re-attribution setting it impacts installs going forward. Meaning it doesn't impact existing installs. 

Re-attribution window use cases

The following sections contain re-attribution window use cases.

First install

A lead (who never had the app installed) engages with either a user acquisition or retargeting campaign and installs the mobile app.

The following happens:

  • A new install (or organic, if no engagement is recorded), is attributed to the media source on the user acquisition dashboards and data
  • A new re-attribution window commences
  • Install and in-app event postbacks are sent to the attributed media source, when configured
  • Following in-app events are also attributed to the same media source

Reinstall

After the first app install, the user uninstalls and reinstalls during the re-attribution window.

The following happens:

  • The install is NOT attributed - it doesn't appear on the dashboard, nor on the data
  • NO install postback is sent to any media source
  • All following in-app events are counted as organic

Re-attribution

After the first app install, during the re-attribution window, the user uninstalls, then engages with a retargeting campaign and reinstalls.
This is called a re-attribution.

The following happens:

  • The install is attributed to the retargeting media source on the retargeting page and data ONLY
  • All following in-app events are attributed to the retargeting media source
  • The re-attribution and its following events don't appear on the user acquisition dashboards, nor on the UA data
  • An install postback is sent to the retargeting media source

New install

The user uninstalls the app. Then, after the re-attribution window ends, the user reinstalls. This reinstall is considered as a first install and brings the same results:
  • A new install (or organic, if no engagement is recorded), is attributed to the media source on the user acquisition dashboards and data
  • A new re-attribution window commences

  • Install and in-app event postbacks are sent to the attributed media source, when configured

  • Following in-app events are also attributed to the same media source

iOS app restored from iCloud backup

Regardless of the re-attribution window, when an application is backed up using iCloud and later restored (on the same device or on another device), AppsFlyer doesn't count it as a new install or reinstall. A user who restores an app from iCloud maintains their AppsFlyer ID and attribution data.
