Privacy Policy

Last updated: May 2026

1. What We Collect

All Markdown-to-PDF, -Word, and -HTML conversion happens inside your browser. Your Markdown content is never sent to our server and we cannot read it.

When you create an account, we store your email address and a record of past conversions (file names, formats, sizes, and timestamps only — never the file content itself).

2. How Conversion Works

HTML is rendered locally with the unified/remark pipeline. Word (.docx) is generated in the browser via the docx package. PDF uses your browser's native print engine (the same engine that "Save as PDF" uses) inside a hidden iframe. In every case, the generated file is created on your device and downloaded directly — no upload, no server round-trip.

3. Data Storage

We use Supabase to host the optional accounts table and the conversion-history log. The only data stored there is what you see on the Dashboard — email and history metadata. Markdown content and generated files are not stored anywhere by us.

4. Cookies

We use essential cookies for authentication. We do not use tracking cookies or third-party analytics.

5. Third-Party Services

We use the following third-party services:

  • Supabase — authentication and history database
  • Vercel — frontend hosting
  • Google — OAuth authentication (optional)
