Last updated: March 12, 2026

This Privacy Policy explains how Project Jules collects, uses, stores, and shares information when you use the Project Jules website, reader experience, and related mobile applications (collectively, the "Services").

This policy is intended to cover both the web product and the mobile app unless a section says otherwise.

1. Information We Collect

We may collect the following categories of information:

• Account information, such as your name, email address, profile image, and sign-in provider details when you create an account or sign in.
• Content you provide, such as uploaded books or files, highlights, notes, saved items, support requests, and other information you choose to submit.
• Reader activity, such as reading progress, reading level preferences, library activity, and interactions with books and reader tools.
• AI interaction data, such as prompts, messages, and context needed to generate chat responses, summaries, or other AI-powered features.
• Usage and device data, such as IP address, browser type, device type, app version, pages or screens viewed, approximate location derived from IP address, and analytics events.
• Authentication and session data, such as session identifiers, refresh sessions, and security-related logs used to keep accounts secure.

2. How We Collect Information

We collect information:

• Directly from you when you create an account or use the Services.
• Automatically when you browse the website or use the mobile app.
• From third parties you choose to use for sign-in or integrated functionality, such as Google authentication.

3. How We Use Information

We use information to:

• Provide, operate, and maintain the Services.
• Authenticate users, sync accounts across web and mobile, and secure accounts and sessions.
• Save your reading progress, highlights, notes, chat history, and uploaded content.
• Power AI-assisted features such as chat, summaries, metadata generation, or reading adaptations.
• Analyze usage, improve features, and diagnose bugs or abuse.
• Comply with legal obligations and enforce our terms and policies.

4. AI Features

Some features may use third-party AI models or infrastructure to process prompts, book content, excerpts, and related context in order to generate responses or other outputs. If you use those features, the content you submit may be transmitted to the relevant AI provider for processing on our behalf.

You should avoid submitting sensitive personal information in prompts, notes, or uploaded content unless you are comfortable with that information being processed to provide the feature.

5. How We Share Information

We may share information in the following circumstances:

• With service providers that host, store, analyze, secure, or help operate the Services.
• With authentication, analytics, storage, database, and AI providers that process data on our behalf.
• If required by law, regulation, legal process, or a valid governmental request.
• To protect the rights, safety, security, and integrity of Project Jules, our users, or the public.
• In connection with a merger, acquisition, financing, or sale of all or part of the business.

We do not sell your personal information.

7. Cookies and Similar Technologies

On the web product, we and our service providers may use cookies and similar technologies to keep you signed in, remember preferences, measure traffic, and improve the website. You can control cookies through your browser settings, although some features may not function properly if cookies are disabled.

8. Data Retention

We retain information for as long as reasonably necessary to provide the Services, maintain account functionality, comply with legal obligations, resolve disputes, and enforce agreements. Retention periods may vary depending on the type of data and the purpose for which it was collected.

10. Data Security

We use reasonable administrative, technical, and organizational measures to protect information. No system is completely secure, and we cannot guarantee absolute security.

11. Children's Privacy

The Services are not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, contact us so we can review and delete the information if appropriate.
