Privacy Policy

Last updated: March 10, 2026

1. Introduction

InkMarshal ("we", "our", or "the Service") is an AI-powered platform for long-form novel creation. This Privacy Policy explains how we collect, use, and protect your information when you use our Service.

2. Information We Collect

2.1 Account Information

When you sign in via Google OAuth or email magic link, we collect:

  • Email address
  • Display name and profile picture (if provided by Google)

2.2 Content You Create

We store the novels, outlines, chat messages, and chapter content you create within the Service.

2.3 Usage Data

We may collect basic usage information such as feature usage patterns and error logs to improve the Service.

2.4 Guest Mode

If you use the Service without signing in, all data is stored locally in your browser. We do not collect or transmit any guest-mode data to our servers.

3. How We Use Your Information

  • To provide and maintain the Service
  • To sync your creative work across devices
  • To process your content through third-party AI providers for novel generation
  • To communicate important updates about the Service

4. Third-Party AI Providers

InkMarshal operates on a "Bring Your Own Key" (BYOK) model. Your creative content is sent to the AI provider you select (for example OpenAI, Anthropic, Google Gemini, or DeepSeek) using your own API key. We do not store your API keys on our servers. They are kept in your browser's local storage.

Please review the privacy policies of the AI provider you choose, as your content will be subject to their data handling practices.

5. Data Storage & Security

Authenticated user data is stored securely using LibSQL/Turso database infrastructure. We implement reasonable security measures to protect your data, including encrypted connections and secure authentication.

6. Your Rights

You have the right to:

  • Access your personal data
  • Export your creative content at any time
  • Delete your account and all associated data
  • Use the Service in guest mode without providing personal information

7. Cookies & Local Storage

We use browser local storage to save your preferences (theme, language, font size) and, in guest mode, your creative content. We use essential cookies for authentication sessions only. We do not use advertising or tracking cookies.

8. Children's Privacy

The Service is not intended for users under the age of 13. We do not knowingly collect personal information from children under 13.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new policy on this page with an updated revision date.
