In-app banking behavior is monitored by BioCatch, a behavioral biometrics service, and usage patterns are tracked by Dynatrace and Firebase Analytics. User data is handled with several serious protection concerns identified across storage and network layers. Feature availability is controlled remotely via LaunchDarkly, meaning the user experience can change without an app update.
