Privacy Policy

Last updated: April 3, 2026

The short version

Mistline collects zero data. No accounts, no analytics, no telemetry, no tracking, no network requests. Everything stays on your Mac.

What Mistline accesses

Mistline reads your local file system to display your project's file tree, previews, and activity. This data is processed entirely on your machine and is never transmitted anywhere.

Specifically, Mistline accesses:

• File and folder names, paths, sizes, and modification times within the project directory you open
• File contents for preview rendering (Markdown, HTML, CSV, images, PDFs)
• File contents for in-app search
• Git history for the changelog view
• .gitignore, .claudeignore, .cursorignore, and .aiderignore files for AI scope analysis

What Mistline stores

Mistline stores the following data locally on your Mac:

• App settings — preferences, shortcuts, panel widths (~/.mistline/settings.json)
• Recent projects — folder paths you've opened (~/.mistline/mistline.db)
• Annotations — notes you add to files (.mistline/annotations.json inside each project)
• Dismissed ghost files — files you've marked as not orphaned (.mistline/ghost-dismissed.json)

All of this data is stored in plain text or SQLite on your local file system. None of it is encrypted because none of it leaves your machine.

What Mistline does NOT do

• No network requests of any kind
• No analytics or usage tracking
• No crash reporting
• No user accounts or authentication
• No cloud storage or sync
• No third-party services, SDKs, or integrations

Third-party services

Mistline itself makes no network requests. However, your purchase is processed through Polar.sh, which handles payment processing and license delivery. Polar.sh has its own privacy policy.

Updates

If Mistline ever adds features that change this policy (such as auto-update checks or optional telemetry), this page will be updated and you will be notified before any data collection begins.
