Privacy Policy

Chinese Tone Gym is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your personal information when you use our AI-powered Chinese pronunciation training service.

Information We Collect

We collect account information (name, email via Google OAuth), audio recordings for pronunciation analysis, practice session data (scores, progress, learning patterns), device and browser information, and usage analytics to improve our service.

Audio Data Handling

Audio recordings are temporarily processed for pronunciation analysis using AI Pronunciation Services and OpenAI. Recordings are not permanently stored on our servers and are deleted after processing. Audio data is used solely for providing pronunciation feedback.

How We Use Your Information

We use your data to provide pronunciation analysis and feedback, track learning progress, personalize your learning experience, improve our AI models and service quality, communicate important updates, and ensure service security and fraud prevention.

Data Sharing and Third Parties

We use trusted third-party services: Google OAuth for authentication, AI Pronunciation Services for audio processing, Supabase for secure data storage, anonymous analytics for usage insights, and payment processors for subscription management. We never sell your personal data.

Data Security and Protection

We implement industry-standard security measures including encrypted data transmission (HTTPS), secure cloud storage with Supabase, regular security audits, and limited access controls. Audio data is processed in real-time and not permanently stored.

Your Privacy Rights

You have the right to access your personal data, request data correction or deletion, download your learning data, opt-out of analytics cookies, and close your account at any time. Contact us at hello@chinesetonegym.com for privacy-related requests.

Cookies and Tracking

We use essential cookies for authentication and user preferences, and session storage for learning progress. We also use anonymous analytics to improve service quality.

Data Retention

Account data is retained while your account is active. Practice session data is kept to track your learning progress. You may request data deletion at any time. Anonymized analytics data may be retained for service improvement.

International Data Transfers

Your data may be processed in the United States and other countries where our service providers operate. We ensure appropriate safeguards are in place to protect your data during international transfers.
