Privacy Policy

Effective date: June 7, 2026

1. Introduction

Billion Japanese Academy ("we", "our", or "us") operates the BillionJapanese mobile application. This Privacy Policy explains how we collect, use, and protect information about users of our app.

By using BillionJapanese, you agree to the collection and use of information as described in this policy. This app is intended for use by enrolled students, teachers, and staff of Billion Japanese Academy only — it is not a public app.

2. Information We Collect

We collect only the minimum information necessary to provide our services:

• Account credentials — your email address and password (stored encrypted)
• Profile information — your name, student/staff code, and profile photo
• Usage data — course progress, attendance records, and enrollment information
• Device information — device type and OS version, for technical support purposes

We do not collect your location, contacts, camera access, or any other device data beyond what is listed above.

3. How We Use Your Information

We use the information we collect to:

• Authenticate your account and provide access to the app
• Display your course content, certificates, and digital ID card
• Allow teachers and staff to record and manage attendance
• Improve the performance and reliability of the app

We do not sell, rent, or share your personal data with third parties for marketing purposes.

4. Data Storage & Security

Your data is stored on secure servers. We use industry-standard encryption for data in transit (HTTPS/TLS) and at rest. Access to personal data is restricted to authorised academy staff only.

While we take reasonable precautions to protect your data, no system is completely secure. We encourage you to use a strong, unique password for your account.

5. Data Retention

We retain your personal data for as long as your account is active or as required to provide our services. If you leave the academy, your data may be retained for up to 1 year for administrative purposes, after which it will be deleted or anonymised.

6. Your Rights

You have the right to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your data (subject to administrative requirements)

To exercise these rights, please contact us using the details below.

7. Children's Privacy

BillionJapanese is intended for use by enrolled academy students and staff. If a student is under 13 years of age, parental consent is required. We do not knowingly collect data from children without appropriate consent.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date. Continued use of the app after changes constitutes acceptance of the updated policy.
