Frequently Asked Questions

Quick answers about MDash. For detailed workflows, read the documentation.

Is MDash free?

Yes. MDash is free and open source under the MIT License. There is no paid tier, sign-up, or account. Browser storage capacity and the documented import and sharing limits still apply.

What can I create with MDash?

You can create notes, technical guides, linked knowledge bases, code-rich documents, mathematical writing, Mermaid diagrams, and Markdown presentations in one browser workspace.

Where are my notes stored?

Vault files and folders are stored in IndexedDB for the current browser profile and site origin. Interface preferences use localStorage, while offline application assets use the browser cache. MDash does not upload notes to a storage service. Keep important backups outside the browser.

Does MDash work offline?

Yes. The core Progressive Web App works offline after its application assets have been cached. Use the Offline Feature Pack in Settings while connected when you also need every bundled math, diagram, and syntax-highlighting asset offline.

Does MDash track me or use cookies?

MDash uses self-hosted Umami analytics for page views, anonymous visit context, selected feature events, and performance measurements. It uses no analytics cookies, respects Do Not Track, excludes URL queries and fragments, and is disabled on shared-document routes. It never sends note text, filenames, vault structure, search text, or shared document content.

Do I need an account to use MDash?

No. There is no sign-up or login. Open the editor and start writing. Vault documents save automatically in the browser, and the footer reports the local save state.

Does MDash support Arabic and other right-to-left languages?

Yes. Rendered blocks automatically detect direction for Arabic, Hebrew, and Persian. You can also force the whole document to left-to-right or right-to-left with Document Metadata or frontmatter. Unicode text, including CJK scripts, remains supported.

Can I write LaTeX math, diagrams, and highlighted code?

Yes. KaTeX typesets inline and display math, Mermaid renders common diagram types, and Shiki highlights fenced code across more than 200 language grammars.

Can I export to PDF and HTML?

Yes. Export a document as its original source, self-contained styled HTML, or a PDF through the browser print dialog. HTML embeds rendered diagrams and required KaTeX fonts. PDF layout and document properties can vary by browser and operating system.

Can I turn a document into a presentation?

Yes. Separate slides with a horizontal rule and press F5 or choose Present. Presentation Mode supports themes, navigation controls, fullscreen, and 16:9 PDF output.

Can I import my existing Markdown notes?

Yes. Import a supported text file, a folder, or a compatible URL. Folder import preserves supported subfolders and most standard Markdown links. Binary attachments are skipped, application-specific syntax may remain plain text, and duplicate basenames can make wiki-link resolution ambiguous.

Is there a mobile app?

MDash runs in modern mobile browsers and can be installed on the home screen as a Progressive Web App. Vaults remain local to each browser and device unless you export and move them yourself.
