Privacy Policy

Effective Date: September 16, 2026

Welcome to Kanzy ("we", "our", or "us"), available at kanzy.app. We are committed to protecting your personal information and your right to privacy. This Privacy Policy explains how we collect, use, and safeguard your data when you use our mobile application and related services.

1. Information We Collect

• Account & Profile Information: If you sign in using Google Sign-In, we receive your name, email address, and profile picture to create and manage your study account.
• Voice & Audio Data: When you practice speaking with our Pronunciation Coach, we process short voice recordings to evaluate your pronunciation and phonetic accuracy. These recordings are analyzed ephemerally and are not used for advertising or marketing.
• Learning & Practice Activity: We save your study progress, flashcard reviews, streak counts, and practice scores to provide spaced repetition and progress tracking.
• Device Identifiers: We collect anonymous device identifiers to manage free daily AI quota limits and ensure reliable service delivery.

2. How We Use Your Information

We use the collected information exclusively to:

• Provide core language learning features, interactive sentence drills, and roleplay simulations.
• Score pronunciation accuracy and deliver personalized coaching feedback.
• Sync your vocabulary decks and progress across devices.
• Maintain app security, prevent quota abuse, and troubleshoot technical errors.

3. Third-Party Services & AI Processing

To provide advanced language feedback, certain features interact with trusted third-party providers:

• Google Cloud & Gemini API: Processes speech, sentence translation, and grammar explanations under strict enterprise privacy standards.
• Google Play Services: Handles secure app distribution and authentication.

We do not sell, rent, or trade your personal information or audio recordings to third parties.

4. Data Retention & Security

We implement industry-standard encryption (TLS/HTTPS) for all data in transit and at rest. We retain your study history as long as your account is active. Audio recordings used for real-time speech evaluation are processed on-demand and discarded after assessment results are returned.

5. Your Rights & Account Deletion

You have the right to access, update, or delete your personal data. You can delete your study history or request complete account deletion at any time by contacting us at support@kanzy.app.
