### Third-Party Data Sharing

Behavioral data flows to four advertising networks: AdMob, AppLovin MAX, Unity Ads, and Facebook Audience Network. Each of these companies uses user activity to inform how ads are targeted across their platforms. RevenueCat receives purchase and subscription information for billing management. Firebase services process account, configuration, and crash data.
