If you serve ads in your app, and your app targets only children, then you must use one of Google Play's certified ad networks. If your app targets both children and older users, you must implement age screening measures and make sure that ads shown to children come exclusively from one of Google Play's certified ad networks.
Ad Network Certification Requirements
- Define what are objectionable ad content and behaviors and prohibit them in the ad network's terms or policies. The definitions should not result in non-compliance with Play's Developer Program Policies.
- Create a method to rate your ad creatives according to age appropriate groups, including at least groups for Everyone and Mature. The rating methodology must align with the methodology that Google supplies to certified networks.
- Allow publishers, on a per-request or per-app basis, to request child-directed treatment for ad serving. Such treatment must be in compliance with at least the US Children's Online Privacy and Protection Act (COPPA) and the EU General Data Protection Regulation (GDPR), including but not limited to:
- restricting the collection and/or use of personal data;
- disabling personalized ads.
- Provide Google with sufficient information to verify the ad network's compliance with all certification requirements, and respond in a timely manner to any subsequent requests for information.
Note: Ad networks must support ad serving that complies with all relevant statutes and regulations concerning children that may apply to their publishers.
Mediation requirements for serving platforms when serving ads to children:
- only use Play certified ad networks or implement safeguards necessary to ensure that all ads served from mediation networks comply with these requirements; and
- pass signals necessary to indicate the ad content rating and any applicable child-directed treatment.
