TL;DR — md2u is a local desktop application. It collects no data, makes no network requests, and never sends anything anywhere.

Data Collection

md2u collects no data of any kind. Specifically:

No analytics or telemetry
No usage tracking
No crash reporting sent to any server
No network requests made by the application at runtime

File Access

md2u reads only the Markdown files you explicitly open — via drag-and-drop, CLI argument, or file association. Files are read locally and never uploaded anywhere.

Network

The application makes no outbound network connections. All rendering — Markdown, Mermaid diagrams, syntax highlighting — is performed locally using bundled assets.

Updates

md2u does not include an auto-updater. New versions are published on the GitHub Releases page and installed manually.

Open Source

The full source code is available at github.com/stanwu/md2u under the GNU General Public License v3.0. You can verify these claims by reviewing the code directly.
