3. AI and Data Processing

This section describes how we handle your data in relation to our AI features:

How AI Uses Your Content

  • Your manuscripts and Codex entries are processed by AI models to provide writing assistance and context-aware suggestions
  • AI processing occurs on secure servers and your content is not permanently stored by the AI provider
  • Voice/style analysis creates a “voiceprint” stored in your account to personalize AI responses

What We Don't Do

  • We do NOT train AI models on your content. Your manuscripts, characters, and creative work are never used to train or improve AI models.
  • We do NOT share your content with third parties for their AI training purposes
  • We do NOT use your content for any purpose other than providing the Service to you

AI-Generated Content

Content generated by AI in response to your prompts is considered your content. However, AI outputs may occasionally be similar to content in the AI model's training data, which predates your use of the Service.

4. Data Sharing

We may share your information with:

  • Service Providers: Third parties who perform services on our behalf (hosting, payment processing, analytics)
  • AI Providers: To process your requests for AI-assisted writing (OpenAI for text, FAL.ai for images)
  • Legal Requirements: When required by law or to protect our rights

We do NOT sell your personal information to third parties.

5. Cookies and Tracking

We use cookies and similar technologies to:

  • Maintain your session and remember your preferences
  • Analyze how the Service is used
  • Provide personalized features

You can control cookies through your browser settings. Disabling cookies may affect some features of the Service.

6. Data Retention

  • Your account data and content are retained as long as your account is active
  • After account deletion, your data is permanently removed within 30 days
  • Some data may be retained longer if required by law or for legitimate business purposes (e.g., billing records)
  • AI processing logs are automatically deleted after 30 days

7. Your Rights

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

  • Access: Request a copy of your personal data
  • Correction: Request correction of inaccurate data
  • Deletion: Request deletion of your data
  • Portability: Export your content in standard formats
  • Objection: Object to certain processing of your data

8. Security

We implement appropriate security measures including:

  • Encryption of data in transit (TLS) and at rest
  • Secure authentication and access controls
  • Regular security assessments and monitoring
  • Employee training on data protection

While we strive to protect your information, no method of transmission over the Internet is 100% secure.

9. Children's Privacy

The Service is not intended for children under 13. We do not knowingly collect personal information from children under 13. If we learn we have collected such information, we will delete it promptly.

10. International Transfers

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

11. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes by email or through the Service. Your continued use of the Service after changes become effective constitutes acceptance of the revised policy.
