The new free version of LoopWorlds won’t ask for or collect any personal data. It uses Google Play Authentication, and may collect anonymous user data for analytics reasons though, on the respective 3rd party servers (Google Play, Unity, and Firebase).
It will also contain Unity Ads. Unity has their own privacy policy for this here: https://unity3d.com/legal/privacy-policy
