Legal Architecture

Privacy Policy: LaTeX Craft Pro

This Privacy Policy describes how LaTeX Craft Pro ("the App") handles your data and protects your privacy. LaTeX Craft Pro is committed to protecting your personal information and maintaining transparency about our data practices.

DATA COLLECTION

LaTeX Craft Pro does NOT collect, store, or transmit any personal data to our servers. The App operates primarily on your local device and does not:

  • Collect personally identifiable information
  • Track user behavior or usage data
  • Use analytics or telemetry for tracking
  • Send document data to external servers
  • Require internet connectivity for main functionality

LOCAL DATA STORAGE

The App stores the following data locally on your device:

  • LaTeX Documents
    Location: %LocalAppData%\LaTeXCraftPro\Documents
    Content: .tex, .bib, and project files you create
    Purpose: Manages your working documents
  • Auto-Save Files
    Location: %LocalAppData%\LaTeXCraftPro\AutoSave
    Content: Automatic backup copies of documents being edited
    Purpose: Protects your work against data loss
  • User Settings
    Location: %LocalAppData%\LaTeXCraftPro\Settings
    Content: Editor preferences, AI settings, compiler options
    Purpose: Remembers your preferences and custom configurations
  • Recent Files
    Location: %LocalAppData%\LaTeXCraftPro\Recent
    Content: List of recently opened files
    Purpose: Quick access to frequently used documents
  • Compiled PDFs
    Location: %LocalAppData%\LaTeXCraftPro\Output
    Content: PDF files generated by LaTeX compilation
    Purpose: Document rendering and preview

All data remains on your device and is never transmitted to external LaTeX Craft Pro servers.

AI FEATURES AND DATA

LaTeX Craft Pro offers two modes of operation for AI features:

  • Local AI Models (LLaMA)
    When you use local AI models, all processing occurs entirely on your device. No document data is transmitted to external servers. You are responsible for downloading and managing local AI models.
  • Cloud AI APIs (OpenAI-compatible)
    When you configure the App to use third-party AI APIs (such as OpenAI, Anthropic, or compatible providers), your document content may be sent for processing to those providers' servers. LaTeX Craft Pro does not control this data after transmission.

You are responsible for reviewing and accepting the privacy policies of any third-party AI provider you choose to use.

DATA ACCESS

LaTeX Craft Pro requires the following permissions to function:

  • File System Access: To read, edit, and save LaTeX documents
  • Internet Access: For downloading LaTeX packages (Tectonic) and cloud AI APIs (optional)
  • System Integration: For document compilation and PDF rendering

These permissions are used exclusively for the App's main functionality and are not used to access unrelated files or data.

THIRD-PARTY SERVICES

LaTeX Craft Pro does NOT:

  • Use third-party analytics services
  • Integrate with cloud storage services (except user-configured AI APIs)
  • Display third-party advertisements
  • Connect to external APIs without your explicit consent and configuration

The only use of external services is when you explicitly configure a third-party AI API for AI assistance features.

DATA SECURITY

Your documents and local data are protected by:

  • Standard Windows file system security
  • Built-in security features of your device
  • Exclusively local storage (no cloud transmission for main functionality)
  • Auto-save system with multiple restore points

We recommend regularly backing up the %LocalAppData%\LaTeXCraftPro folder to avoid data loss.

DATA RETENTION

Documents remain on your device until you delete them through the App or manually. Auto-save files are maintained according to your retention settings. Settings and preferences persist until you reinstall the App or manually delete the configuration folder.

CHILDREN'S PRIVACY

LaTeX Craft Pro does not collect personal information from anyone, including children. The App is suitable for users of all ages, with the restriction that users under 13 should not use the App without parental consent, as per our Terms of Use.

CHANGES TO THIS PRIVACY POLICY

We may update this Privacy Policy periodically. Significant changes will be communicated through:

  • App updates on Microsoft Store
  • Updated policy within the App
