✅ All processing happens locally on your device — no information leaves your phone.
3. Voice Input and Speech Recognition

For more information on how Google handles your voice input, refer to the Google Privacy Policy.
4. Text-to-Speech (TTS)

This feature runs completely on your device.
No spoken or generated text is stored or transmitted.

- Since we do not collect personal information, there is no risk of user data leakage from our side.
7. Third-Party Libraries
