Fingerprint Android Fraud Prevention is a device identification and fraud detection SDK for Android applications. It generates a stable visitor ID for each device by combining device, behavioral, and network signals to identify returning users and detect fraudulent activity. The product targets several fraud vectors including account takeover, SMS pumping attacks, fraudulent transactions, promotion abuse, chargeback fraud, and ban evasion via multiple account creation. It uses device fingerprinting to maintain identification accuracy over time without introducing friction into the user experience — triggering additional authentication only when anomalous behavior is detected. Signal collection includes VPN detection, bot detection, and emulator detection alongside device and behavioral signals. The SDK is available for Android native (Kotlin/Java), React Native, and Flutter, and is configured via an API key with support for custom endpoints and fallback endpoint URLs. A free tier offers up to 500,000 monthly Android API calls per company, available permanently for qualifying accounts on the Pro Plus or Free plans. Usage beyond 500K calls triggers an upgrade prompt or overage billing at $4 per 1K calls. API usage is tracked per platform in a dashboard.
