Question 1

Which Markdown syntax is supported?

Accepted Answer

GitHub-flavored Markdown: headings, emphasis, links, images, blockquotes, ordered and unordered lists, inline code and fenced code blocks, tables, and horizontal rules. The preview renders exactly what the HTML export will contain.

Question 2

Where is my text saved and for how long?

Accepted Answer

In your browser's localStorage on this device, a few hundred milliseconds after each edit. It survives reloads and browser restarts, but it is per-browser and per-device, and clearing site data removes it — use the HTML download (or copy your Markdown out) for anything you need to keep.

Question 3

What does the HTML download contain?

Accepted Answer

A single self-contained .html file with your rendered content and a small embedded stylesheet — no external scripts, fonts, or trackers. It opens in any browser and is easy to mail, host, or print.

Question 4

Is the rendered HTML safe?

Accepted Answer

The output is sanitized with DOMPurify before being shown or exported, which strips script tags and event-handler attributes. You can paste Markdown from untrusted sources without it executing anything in the preview.

Question 5

Is my document uploaded anywhere?

Accepted Answer

No. Editing, rendering, saving, and exporting all happen inside your browser; the document never leaves your device, nothing is uploaded or tracked, and the editor works offline once the page has loaded.
