## 3. Microphone Permission Explanation
Some features of LingoAI (such as voice-based answering) require access to your device's microphone. Specific details are as follows:

- **Data Processing**: Voice input may be processed by us or our service providers (such as speech recognition service providers) to deliver the corresponding functionality. We do not use your voice data for any purposes other than providing services.
- **Permission Management**: You can disable microphone permission at any time in your device's Settings under "Privacy" - "Microphone." Disabling it will prevent related voice-based features from functioning but will not affect the normal use of other features.
