Privacy Policy
Last updated: March 4, 2026
1. Introduction
Logos X (“we,” “us,” or “our”) respects your privacy and is committed to protecting your personal data. This Privacy Policy explains how we collect, use, store, and protect your information when you use the Logos X desktop application and related services (the “Service”). By using the Service, you agree to the practices described in this policy.
2. Information We Collect
2.1 Account Information
When you create an account (required for the paid tier), we collect your email address and basic profile information through our authentication provider (Auth0). This is used to manage your account and process payments.
2.2 Payment Information
Payment processing is handled entirely by Stripe. We do not store your credit card numbers, bank account details, or other financial information on our servers. We receive only transaction confirmations, amounts, and Stripe customer identifiers. Please refer to Stripe’s Privacy Policy for details on how they handle your payment data.
2.3 User Content
The documents (PDFs) and video URLs you provide are processed to generate courses. In the free tier, your content is sent directly from your device to the third-party AI provider you configure (e.g., OpenAI, DeepSeek, Google Gemini). In the paid tier, your content is sent to our cloud API, which forwards it to our AI provider for processing. We do not permanently store your uploaded documents or video transcripts on our servers — they are used only during the course generation process and discarded afterward.
2.4 Locally Stored Data
Logos X is primarily a desktop application. The following data is stored locally on your device and never transmitted to our servers:
- Generated course content (lessons, quizzes, study guides)
- Your learning progress and quiz results
- Essay submissions and feedback
- AI provider API keys (free tier)
- Text-to-speech audio files
- Application settings and preferences
- Gamification data (streaks, XP, achievements)
2.5 Usage Data
We do not collect analytics, telemetry, or usage tracking data. We do not use cookies, tracking pixels, or similar technologies in the desktop application. The landing website (logosx.space) uses only essential cookies required for basic functionality.
3. How We Use Your Information
We use the information we collect to:
- Provide, maintain, and improve the Service
- Process payments and manage your account
- Generate AI-powered educational content from your materials
- Communicate with you about your account or service-related matters
- Detect and prevent fraud or abuse
- Comply with legal obligations
We do not sell, rent, or trade your personal information to third parties. We do not use your data for advertising purposes.
4. Third-Party Services
The Service integrates with the following third-party providers. Each has their own privacy policy governing how they handle your data:
| Service | Purpose | Data Shared |
|---|---|---|
| Auth0 | Authentication | Email, profile info |
| Stripe | Payment processing | Payment details (handled by Stripe) |
| AI Providers | Course generation | Document text, video transcripts |
| YouTube | Video metadata & transcripts | Video URLs |
When using the free tier, your content is sent directly to the AI provider you configure. We have no access to or control over this data exchange. When using the paid tier, your content passes through our cloud API before reaching the AI provider.
5. Data Security
We implement appropriate technical and organizational measures to protect your data. All communications between the desktop application and our cloud services are encrypted using TLS (HTTPS). Payment processing is handled by Stripe, which is PCI DSS Level 1 certified. Your locally stored data is protected by your device’s own security measures (disk encryption, user accounts, etc.). However, no method of transmission over the Internet or electronic storage is 100% secure, and we cannot guarantee absolute security.
6. Data Retention
Account data: We retain your account information for as long as your account is active. If you request account deletion, we will remove your data within 30 days, except where retention is required by law.
Payment records: Transaction records are retained as required by applicable tax and financial regulations.
User content: Documents and transcripts submitted for course generation (paid tier) are processed in real time and are not permanently stored on our servers.
Local data: Data stored on your device persists until you delete it or uninstall the application. We have no access to your locally stored data.
7. Your Rights
Depending on your jurisdiction, you may have the following rights regarding your personal data:
- Access: Request a copy of the personal data we hold about you.
- Correction: Request correction of inaccurate or incomplete personal data.
- Deletion: Request deletion of your personal data, subject to legal retention requirements.
- Portability: Request your data in a structured, commonly used, and machine-readable format.
- Objection: Object to the processing of your personal data in certain circumstances.
- Withdrawal of consent: Withdraw consent at any time where processing is based on consent.
To exercise any of these rights, please contact us at [email protected]. We will respond to your request within 30 days.
8. Children’s Privacy
The Service is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that we have collected personal data from a child under 13, we will take steps to delete that information promptly. If you believe we have inadvertently collected information from a child under 13, please contact us.
9. International Data Transfers
Our cloud services may process data in regions outside your country of residence. By using the paid tier of the Service, you consent to the transfer of your data to servers that may be located in different jurisdictions. We ensure appropriate safeguards are in place for any international data transfers.
10. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of material changes by updating the “Last updated” date at the top of this page. Your continued use of the Service after any changes constitutes your acceptance of the updated policy. We encourage you to review this policy periodically.
