5. Analytics and Marketing Attribution

We use third-party service providers, including AppsFlyer, Firebase, and RevenueCat, to operate the app, analyze usage, measure app installs and marketing campaign performance, process in-app purchase related events, and help prevent fraud.

AppsFlyer may process device and app information, attribution identifiers such as AppsFlyer ID and IDFV, advertising identifiers such as IDFA only where enabled and permitted by your device settings and consent choices, IP address, usage events, customer user ID, sign-in method, purchase event details such as product ID, currency, amount, and transaction ID, and similar technical information.

This information may be used for analytics, attribution, advertising measurement, fraud prevention, and service operation. In the current iOS app, we disable collection of the advertising identifier (IDFA) and do not use this information to track you across other companies' apps and websites. If a future version uses data for tracking, we will request permission where required and update our disclosures.
