    Method and Limitations

    Static analysis only. CITT reviewed the code of this build without running the app, so runtime behavior was not observed. The findings below describe the analyzed build and may not reflect server-side controls or later versions. CITT makes no determination about compliance with any law or platform policy; it reports what the artifacts contain and cites the published guidance so a reader can compare.

    What Data is Collected

    Multiple analytics platforms collect data on in-app behavior, feature usage, and session patterns. PostHog, Firebase Analytics, and Google Analytics each receive a continuous stream of user activity within the app, building a detailed record of how the app is used over time.

    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.

    Areas for Improvement

    • Behavioral data is shared with four separate advertising networks, giving multiple companies an ongoing view of how the app is used.
