Privacy Policy

Last updated: January 31, 2026

Welcome to Lexi ("we," "our," or "us"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application Lexi (the "App").

1. Information We Collect

1.1 Information You Provide

• Account Information: When you register, we collect your email address, username, and password.
• Profile Information: Optional information such as your display name and avatar.
• Learning Preferences: Your native language, target language, and learning goals.

1.2 Information Collected Automatically

• Learning Progress: Words learned, content viewed, game scores, and achievement data.
• Usage Data: App interactions, session duration, and feature usage to improve our service.
• Device Information: Device type, operating system, and app version for compatibility purposes.

2. How We Use Your Information

We use the collected information to:

• Provide and maintain the App's language learning features
• Personalize your learning experience with AI-powered content recommendations
• Track your progress and provide spaced repetition reviews
• Enable social features like friends, communities, and challenges
• Send notifications about your learning streak and goals (if enabled)
• Improve and optimize the App's performance and features
• Communicate important updates about our service

3. Data Sharing and Disclosure

We do not sell your personal information. We may share your information only in these circumstances:

• With Your Consent: When you explicitly agree to share (e.g., public profile, leaderboards)
• Service Providers: Trusted third parties who assist in operating our App (cloud hosting, analytics)
• Legal Requirements: When required by law or to protect our rights and safety

4. Data Security

We implement industry-standard security measures to protect your data, including:

• Encrypted data transmission (HTTPS/TLS)
• Secure password hashing
• Regular security audits
• Access controls and authentication

5. Your Rights and Choices

You have the right to:

• Access: Request a copy of your personal data
• Correction: Update or correct inaccurate information
• Deletion: Request deletion of your account and associated data
• Portability: Export your learning data
• Opt-out: Disable notifications and certain data collection in Settings

6. Data Retention

We retain your data for as long as your account is active. If you delete your account in the app, we remove at once your personal information and everything tied to you: your XP, streak and achievements, your words and reading progress, your comments, likes, community posts, friendships and challenge entries. Only counts no longer tied to you remain, plus records we must keep by law (for example purchase receipts held by Apple or Google).

7. Children's Privacy

Lexi is not directed at children under 13 years of age. We do not knowingly collect personal information from children under 13. If you believe we have collected such information, please contact us immediately.

8. International Data Transfers

Your data may be processed in countries other than your own. We ensure appropriate safeguards are in place for international transfers in compliance with applicable data protection laws.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes through the App or via email. Your continued use of the App after changes constitutes acceptance of the updated policy.
