Privacy Policy

1. Introduction

Welcome to Tsuzuki Connect ("Tsuzuki Connect," "we," "our," or "us"). We are committed to protecting your privacy and ensuring you have a positive experience using our language learning application. This Privacy Policy explains how we collect, use, and safeguard your information when you use our mobile application, desktop application, website, and related services (collectively, the "Services").

Please read this Privacy Policy carefully. By accessing or using our Services, you acknowledge that you have read, understood, and agree to be bound by all the terms of this Privacy Policy and our Terms of Service. If you do not agree with our policies and practices, please do not use our Services.

2. Information We Collect

• Communication: Information you provide when you contact us for customer support, feedback, or other inquiries.
• Purchase Information: If you make in-app purchases, we process minimal transaction data necessary to complete your purchase.

3. How We Use Your Information

We use the information we collect for various purposes, including:

• Providing and Improving Services: To operate, maintain, and enhance our Services, develop new features, and address technical issues.
• Personalization: To customize your language learning experience locally on your device, including adapting content difficulty based on your proficiency, suggesting review materials, and tailoring the narrative experience.

• Security: To detect, prevent, and address technical issues and protect the security of our Services.
• Legal Compliance: To comply with applicable laws, regulations, and legal processes.

4. Data Security

We implement appropriate technical and organizational measures to protect your personal information. Since Tsuzuki Connect primarily stores data locally on your device, most of your information is protected by your device's security measures.

4.1 Local Data Security

For data stored locally on your device:

• Your game progress, learning data, and preferences are stored in secure, application-specific storage areas on your device.
• We recommend keeping your device's operating system and Tsuzuki Connect updated to ensure you have the latest security improvements.
• Consider enabling your device's built-in security features (e.g., passcode, biometric authentication) to prevent unauthorized access.

4.2 Cloud Data Security (Optional Feature)

If you enable optional cloud features:

• Data transmitted to our servers is encrypted during transit using industry-standard TLS/SSL protocols.
• Server-side data is stored in secure, access-controlled environments with regular security audits.
• We implement authentication mechanisms to ensure that only you can access your cloud-stored data.

5. Your Rights and Choices

Since Tsuzuki Connect primarily stores your data locally on your device, you maintain direct control over most of your information. However, we still respect and support your privacy rights, which may include:

• Access and Control: You can access, modify, or delete most of your information directly within the application and through your device's file management system.
• Cloud Data (If Applicable): If you've enabled our optional cloud features, you can request access to, correction, or deletion of your cloud-stored data by contacting us.
• Communication Preferences: You can manage your communication preferences within the application settings.
• Account Deletion: If you created an optional online account, you can delete it at any time through the application or by contacting us.

5.1 Application Settings

Tsuzuki Connect provides several privacy-related settings directly in the application:

• Cloud Sync: Enable or disable syncing your data to our servers (disabled by default).
• Error Reporting: Control whether anonymous diagnostic data is sent to help improve the application (opt-in only).
• Data Backup: Create local backups of your game data and learning progress.
• Data Reset: Clear all locally stored data and start fresh.

5.2 Device Permissions

Tsuzuki Connect uses minimal device permissions to function. You can review and modify these permissions through your device's settings:

• Storage: Required to save your game progress locally.
• Network Access: Only required for optional online features.

6. Children's Privacy

Our Services are not directed to children under the age of 13 (or 16 in the European Union). We do not knowingly collect personal information from children under these ages. If we learn that we have collected personal information from a child under these ages, we will take steps to delete that information as quickly as possible.

If you are a parent or guardian and believe that your child has provided us with personal information without your consent, please contact us using the information provided in the "Contact Us" section.

7. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date at the top. You are advised to review this Privacy Policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page.

If we make material changes to this Privacy Policy, we will notify you through a notice on our Services or by other means as required by applicable law.
