Action steps for the Google Families policy update

Starting from the beginning of April, the Google Families policy will no longer allow Device IDs to leave users’ devices from apps where one of the target audiences is children. 

Developers with Android apps that exclusively use the Unity Ads SDK and are a part of Google Play’s Families policy program need to configure Unity Ads to comply with policy changes by April 1. 

Here is what you will need to do:

Step #1: Confirm you are sharing the correct values in the following fields:

MetaData field



Indicates the compliance mode for the app:


App: Indicates that the entire app is directed at children.


Mixed: Indicates that the app is directed at mixed audiences, and passes user-specific flags that identify whether a user should receive personalized or contextual advertisements.


None: Indicates that the entire app is not directed at children and the Families policy does not apply. 


A user-specific flag that indicates whether a user should receive personalized or contextual advertisements.


True: Indicates that the user may not receive personalized ads.


False: Indicates that the user may receive personalized ads.


Please note: This field is only required if privacy.mode is set to mixed. For more information, see documentation on COPPA compliance and contextual ads.


Step #2: Add the appropriate code to your project

Step #3: For publishers using Unity Mediation – upgrade to 0.3.0 or above

Publishers who are using Unity Mediation and are operating applications targeted toward children will need to be on Mediation SDK version 0.3.0 or above before re-publishing to the Google Play Store. 

Please note that at this time, Unity Mediation does not support mixed audience mode or the user-specific flags referenced above.

Step #4: Re-publish your app to the Google Play Store

Consolidating multiple API keys to retrieve user acquisition data

If your organization uses more than one API key to retrieve user acquisition data, we recommend that you consolidate and use one unique key. This helps with security for your organization and cuts down on the complexity of managing multiple API keys.

Implement and update your app-ads.txt file

The app-ads.txt file was created by IAB to combat fraud and to create transparency in the advertising ecosystem by identifying which platforms publishers have authorized to sell their inventory. 

The file creates a layer of transparency that benefits both publishers and buyers as it verifies the legitimacy of sellers, protecting against fraud and misrepresented domains. 

For those who have already implemented this file, we highly recommend updating it as we have added new partners.
