Privacy Policy

1. Introduction

LunaSoft ("we", "us", or "our") develops and publishes mobile applications under the Luna brand, including but not limited to Luna Russian Reading, Luna Stories, and related language learning applications (collectively, the "Apps"). This Privacy Policy explains what information we collect, how we use it, and your choices regarding your data when you use our Apps.

2. Information We Collect

2.1 Information You Do Not Provide

The Apps do not require user registration. We do not collect your name, email address, phone number, photo, location, contacts, or any other personally identifiable information.

2.2 Content You Submit to AI Features

Some Apps include AI-powered features such as text generation, reading comprehension, or translation. When you use these features, the text or prompt you submit is sent to our backend service and forwarded to OpenAI or Microsoft Azure OpenAI Service for processing. This content is used solely to generate the response you requested.

• What is sent: The text content you input into AI features.
• What is NOT sent: Your name, device identifiers, location, or any account information.
• Retention: We do not store your AI prompts on our servers beyond what is required to deliver the response. OpenAI and Azure OpenAI handle the data according to their own enterprise data policies.

2.3 Locally Stored Data

Your learning progress, saved words, reading history, and preferences are stored locally on your device. This data does not leave your device and is not accessible to us. If you uninstall the App, this data is deleted.

2.4 Purchases and Subscriptions

Any in-app purchases or subscriptions are processed entirely by Google Play (on Android) or the Apple App Store (on iOS). We do not receive or store your payment information, credit card numbers, or billing address. We only receive a confirmation that a purchase was made.

3. How We Use Information

The limited information processed through our Apps is used only to:

• Provide AI-generated responses to the prompts you submit.
• Operate, maintain, and improve the functionality of the Apps.
• Comply with applicable legal obligations.

We do not sell, rent, or trade any user information. We do not use your data for advertising or build user profiles.

4. Third-Party Services

To provide AI features and distribute our Apps, we rely on the following third-party processors:

• OpenAI — openai.com/policies/privacy-policy
• Microsoft Azure OpenAI Service — privacy.microsoft.com/privacystatement
• Google Play (Android) — policies.google.com/privacy
• Apple App Store (iOS) — apple.com/legal/privacy

These providers process data under their own privacy policies. We encourage you to review them.

5. Data Security

All communication between the Apps and our backend servers is encrypted using HTTPS/TLS. We follow industry-standard practices to protect data in transit. However, no method of transmission over the internet is 100% secure, and we cannot guarantee absolute security.

6. Children's Privacy

Our Apps are intended for users aged 13 and above. We do not knowingly collect any information from children under 13. If you believe a child under 13 has provided information to us, please contact us and we will take steps to remove it.

7. Your Rights

Because we do not store personally identifiable user data on our servers, there is generally no personal data for us to access, correct, or delete. However, depending on your jurisdiction (such as the EU under GDPR or California under CCPA), you may have the following rights:

• The right to access any data we may hold about you.
• The right to request deletion of any data.
• The right to object to processing.
• The right to lodge a complaint with a data protection authority.

To exercise any of these rights, contact us at the email address below.

8. Changes to This Policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top of this page indicates when the most recent changes were made. We encourage you to review this policy periodically.
