Privacy Policy & Data Security

Your privacy is our top priority. Learn how we protect your data and what information we collect.

Last updated: April 27, 2026

🔒 What Stays Local, What Doesn’t

The live preview, PDF export, HTML export, and Markdown export all run entirely in your browser. That content never touches our servers — it’s parsed, rendered, and packaged in JavaScript on your machine.

DOCX export is the one exception. By default, the converter POSTs your markdown text to /api/convert-to-docx so server-side Pandoc can produce a higher-fidelity Word file. Pandoc reads your markdown from a temp file, generates the .docx, the temp files are immediately deleted, and the binary streams back to your browser. We don’t log document content, persist it, or send it anywhere else. The whole roundtrip takes a second or two.

If the Pandoc route is unreachable or fails, the converter automatically falls back to a fully-local DOCX path using the docxnpm package. If you’d rather skip the server roundtrip entirely, you can use that fallback by blocking the /api/convert-to-docx endpoint in your browser, or just stick to PDF/HTML/Markdown export.
