## 1. Information We Collect
To provide you with our AI-powered speaking feedback and learning experience, we collect the following categories of information:
### A. Information You Provide Directly
* **Account Information:** When you register, sign in, or create a profile, we collect details such as your full name, email address, phone number, and password.
* **Learning Goals and Level:** We collect info about your English learning objectives (e.g., travel, business, daily life) and your self-reported proficiency level to customize your lessons.
### B. Voice and Audio Data (Crucial for App Functions)
* **Microphone Input & Voice Recordings:** To analyze your pronunciation, fluency, and grammar, our App requires permission to access your device’s microphone. We record and collect the audio clips of you speaking the target English sentences.
* **Evaluation Transcripts:** We process and store the text transcriptions of your spoken responses along with the pronunciation scores generated by our AI models.
### C. Automatically Collected Data
* **Usage Data:** We collect information about your interaction with the App, such as lessons started, completed sentences, XP earned, streak duration, time spent practicing, and feature settings.
* **Device Information:** We collect data about the device you use to access the App, including your IP address, device model, operating system version, unique device identifiers (UUID), language settings, and crash reports.
### D. Purchase and Subscription Information
* All transactions are processed securely through the Google Play Store or Apple App Store. We do not store or process your credit card details or financial information directly. We only receive confirmation tokens of your active premium subscription state.

## 3. How We Share Your Information
We do not sell, trade, or rent your personal data to third parties. We only share information with third-party service providers under strict privacy terms to help us operate the App:

* **Legal Requirements:** We may disclose your information if required to do so by law, or in response to valid requests by public authorities.

## 4. Microphone Permissions
The App requires access to your device's microphone to analyze and grade your spoken English.
* Microphone permission is requested dynamically.
* You can revoke this permission at any time through your device's settings; however, voice evaluation features will not function without it.

## 5. Data Security & Retention
We take data security very seriously and implement appropriate technical and organizational measures to prevent unauthorized access, alteration, or disclosure.
* **Encryption:** All personal data and audio transmissions are encrypted in transit using industry-standard SSL/TLS protocols.
* **Retention:** We retain your account profiles, learning progress, and voice history for as long as your account is active. Audio files are retained only as long as necessary to provide speech evaluations and diagnostics.
