Kanzy App

Privacy Policy

Effective Date: October 10, 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 or create an account, we receive your name, email address, and profile picture to create and manage your study account.
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. Camera & Image Capture (Visual AI Vocabulary Scanner)

When you use the Visual AI Vocabulary Scanner feature, Kanzy may request access to your device camera and photo library:

Photo Capture & Upload: Users may choose to take a photo or select an existing picture from their photo library to identify objects and learn relevant vocabulary.
Secure Processing & AI Analysis: Captured images are transmitted securely using TLS encryption and processed by artificial intelligence vision models solely to recognize real-world objects and extract vocabulary translations.
Temporary Storage & Session Recovery: Images are stored temporarily in secure encrypted cloud storage to allow you to restore your most recent scan without consuming additional daily AI credits, and for diagnostic and troubleshooting purposes. Images are not retained permanently and are automatically purged over time.
No Biometric or Facial Recognition: Kanzy does not use your photos for facial recognition, biometric profiling, identity verification, or third-party marketing. Images are processed strictly for language learning and educational object recognition.

3. Microphone & Audio Data (Pronunciation Coach & Voice Practice)

When you practice speaking through our Pronunciation Coach, interactive sentence drills, or conversational roleplay simulations, Kanzy requests permission to access your device microphone:

Audio Recording: Microphone access is used exclusively when you actively initiate voice recording exercises.
Phonetic Evaluation: Short audio recordings are processed to analyze phonetic accuracy, provide real-time pronunciation feedback, assess speech fluency, and score dialect alignment.
Temporary Processing: Voice audio is processed ephemerally on-demand. Kanzy does not sell, rent, or trade your voice recordings, nor do we use your voice data to train public third-party AI models.

4. Advertising Identifiers & Analytics (Google AdMob)

To support free access to language learning resources, Kanzy integrates Google AdMob to display rewarded and interstitial advertisements to free-tier users:

Data Collected by AdMob: The Google Mobile Ads SDK may collect and process device identifiers (including Google Advertising ID / GAID on Android and IDFA on iOS, where permitted), IP address for coarse approximate location, app performance diagnostics, and app interaction data.
Purpose: This data is utilized by Google to deliver, measure, and personalize advertisements, detect fraud, and enforce frequency capping. Kanzy Pro subscribers do not see ads and are not subject to AdMob ad tracking.
Google Privacy Policy & Opt-Out: For more details on how Google uses data from apps, please review the Google Privacy Policy and Google Advertising Technologies. You can manage or reset your advertising identifier and opt out of personalized ads via your device system settings (e.g., Android Settings > Google > Ads, or iOS Settings > Privacy & Security > Tracking).

5. How We Use Your Information

We use the collected information exclusively to:

Provide core language learning features, interactive sentence drills, visual object scanner, 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.

6. Third-Party Services & AI Processing

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

Google Cloud & Gemini API: Processes speech, visual object recognition, sentence translation, and grammar explanations under strict enterprise privacy standards.
Google AdMob: Serves mobile advertisements to free-tier users.
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.

7. 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.

8. 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 [email protected].
