If apps are directed to Under 13 and serving contextual ads only, is information like device ID/IP etc still collected/used by Unity? Is any information collected//used?
Hello grapemedia,
About COPPA(Children’s Online Privacy Protection Act), please refer to our website for more information. In the following document, paragraphs 3&4 explain what data we collect/use. https://docs.unity3d.com/Manual/UnityAnalyticsCOPPA.html
Please let me know if you still have questions.
Have a good day!
Hello! That page is now a 404. Do you have an updated link?
I changed my ads to “contextual ads only”. From what I can gather, Unity now doesn’t collect any user info. Is that correct?
I put “does not collect any user info” and Apple accepted and published the app; however, Google has rejected it. 
Sorry I can’t answer the legal-related questions, I suggest you check the Google Play data safety section for Unity Ads, and if you have any questions about this please contact DPA@unity3d.com.
