4. Audio & System Speech Synthesis
Pronunciation audio in the application is generated locally on your device using the operating system's built-in Text-to-Speech (TTS) engine (such as Android TTS or iOS Speech Synthesis). No audio queries are processed or uploaded over the internet.

Our application contains zero third-party advertising SDKs, zero cross-app tracking frameworks, and zero analytics software (such as Google Analytics or Firebase Analytics).
