Last updated: August 24, 2026

1. Introduction

Mindory ("we," "our," or "us") takes your privacy seriously. This Privacy Policy explains how we collect, use, store, and protect your personal information. By using Mindory, you agree to the practices described in this policy.

2. Data Storage Location

All book content is stored on your local device. We do not upload your book content to any server. Your reading data, notes, and highlights are stored in your device's local storage.

3. AI Interactions & Data Transmission

When you use the AI Q&A feature:

  • Only your question and the relevant text context are sent
  • Complete book content is never transmitted
  • Your personal information or device information is not sent
  • AI service providers' (if any third-party) data processing is governed by their own privacy policies

4. Information We Collect

As a local-first application, Mindory minimizes data collection. Information we may collect includes:

  • Usage Data: Anonymous usage statistics to improve product experience
  • Crash Reports: Technical diagnostic information when the app crashes, excluding book content
  • User Feedback: Feedback and suggestions you voluntarily submit

5. Information We Do Not Collect

  • Book content
  • Reading notes and highlights
  • Personal identifying information (name, email, etc.)
  • Device unique identifiers
  • Location information

6. Third-Party Services

Mindory may use the following third-party services:

  • App Distribution Platforms: Such as Apple App Store, governed by their privacy policies
  • Crash Analytics Services: For diagnosing technical issues

7. Data Security

We take reasonable technical and organizational measures to protect your data. Since book and reading data is stored locally, your data security primarily depends on your device's security. We recommend keeping your device secure and backing up your data.

8. Data Retention

Your local books and reading data will remain on your device until you delete them. We do not retain any book content or reading records on servers. Uninstalling the app will delete all local data.

Mindory is not directed to children under 13. We do not knowingly collect personal information from children.
