1. Information We Collect
We may collect the following types of data to support app functionality:
- **Microphone Access (RECORD_AUDIO):**
Used to analyze speech input for pronunciation feedback and language translation. Audio is processed in real-time and is **not stored or shared**.
- **Camera Access (CAMERA):**
Used for scanning printed materials containing English text (for OCR and grammar correction). Images are processed on-device or securely uploaded for text recognition, and are **not stored after processing**.
- **Media Access (READ_MEDIA_IMAGES/VIDEO/AUDIO):**
Used to allow users to select images containing text for translation or grammar assistance. We only read the selected file, and do not scan your media library.
- **Text Input:**
Any text you type or extract from image will be sent to **third-party APIs (e.g., OpenAI GPT-3.5)** for translation, grammar correction, or content generation. We **do not collect or associate this with personal identity**.
- **Authentication Data:**
We use **Firebase Authentication** to let users register and log into the app using email and password. Firebase stores your email address and assigns a unique user ID (UID). We do **not collect passwords**, and we do **not access any other personal information**.

2. How We Use the Information
We use the collected information solely to:
- Provide real-time pronunciation and translation feedback
- Generate grammar corrections and speech drafts via AI
- Authenticate users and manage access
- Enhance user experience
We **do not sell**, share, or use your data for advertising purposes.

3. Third-party Services We Use
We use the following external services strictly for functionality:
- **Firebase Authentication** – For secure login and user account management.
- **OpenAI API (GPT-3.5)** – For grammar correction, translation, and content generation.
- **Google ML Kit & TTS** – For text recognition (OCR), language detection, and text-to-speech.
- **Google Play Services** – For app functionality and analytics.
These services may temporarily process your data but do **not store it** or use it for other purposes.
