Privacy Policy

1. Introduction

Lernt ("we", "us", or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, store, and share information when you use our AI-powered learning platform ("the Service").

2. Information We Collect

Account information: When you create an account, we collect your email address, display name, and authentication credentials.

Learning data: We store courses, lessons, exercises, quizzes, and progress data that you generate and interact with on the platform.

API keys: If you provide API keys for third-party AI providers, we store them in encrypted form to make requests on your behalf.

Usage data: We collect information about how you use the Service, including pages visited, features used, and interactions with generated content.

3. How We Use Your Information

We use the information we collect to:

• Provide, maintain, and improve the Service
• Generate personalized learning content based on your requests
• Track your learning progress across courses, modules, and lessons
• Communicate with you about your account and the Service
• Ensure the security and integrity of the Service

4. AI Provider Data Handling

When you generate content, your prompts and preferences are sent to third-party AI providers (such as Anthropic or OpenAI) to produce learning materials. These requests are made server-side using your stored API keys. We do not control how AI providers process or retain the data sent to them — please review their respective privacy policies for details.

5. API Key Storage

Your API keys are encrypted at rest and are only decrypted server-side when making requests to AI providers on your behalf. API keys are never exposed to the client-side application, shared with other users, or used for any purpose other than generating content you have requested.

6. Cookies and Local Storage

We use cookies and browser local storage to maintain your session, remember your preferences, and ensure the Service functions correctly. We do not use tracking cookies for advertising purposes.

7. Data Retention

We retain your account and learning data for as long as your account is active. If you delete your account, we will remove your personal data within 30 days, except where retention is required by law. Anonymized, aggregated data may be retained indefinitely for analytics and service improvement.

8. Third-Party Services

The Service integrates with third-party AI providers to generate content. We may also use third-party services for hosting, analytics, and infrastructure. These services have their own privacy policies, and we encourage you to review them. We do not sell your personal data to third parties.

9. Data Security

We implement reasonable technical and organizational measures to protect your data, including encryption of API keys, secure server infrastructure, and access controls. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

10. Your Rights

Depending on your jurisdiction, you may have the right to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your data
• Export your data in a portable format
• Object to or restrict certain processing of your data

To exercise any of these rights, please contact us at usingai.app@gmail.com.

11. Children's Privacy

The Service is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal information, please contact us and we will take steps to delete such information.

12. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of material changes by posting the updated policy on the Service with a revised "Last updated" date. Your continued use of the Service after any changes constitutes acceptance of the updated policy.
