Markdown Studio — Privacy Policy

Last updated: 2026-06-10

Summary

This extension does not collect, transmit, or share any personal data. All Markdown rendering happens locally inside your browser tab. No content from your .md files leaves your machine.

What data the extension touches

Data	What	Where it lives
The text of the `.md` file you opened	Parsed and rendered into HTML	In-memory only, inside the browser tab. Discarded when the tab closes.
Display settings	Reading font, font size, content width, and colour theme (`markdown-studio-font`, `markdown-studio-theme`, `markdown-studio-font-size`, `markdown-studio-content-width`)	`localStorage` of the current origin. Never transmitted.
TOC collapse/expand preference	A single boolean (`markdown-studio-toc-hidden`)	`localStorage` of the current origin. Never transmitted.
File-access tip dismissal	A single boolean (`markdown-studio-file-tip-dismissed-v1`)	`localStorage` of the current origin. Never transmitted.
Comments you add to a document	The note text you type, plus the quoted passage, its surrounding context, and the nearest heading it anchors to (`markdown-studio-comments::…`)	For local (`file://`) files: saved in `localStorage` so they persist across reloads. For web (`http(s)`) pages: kept in memory only and cleared on refresh. Never transmitted.

When you choose Word (.docx) from the Export menu, the extension additionally fetches each <img> referenced by the rendered article so it can embed the image bytes into the downloaded .docx. These fetches go to whatever URLs the original .md references — the extension does not add destinations of its own, and the action happens only when you explicitly export.

What the extension does NOT do

No cookies, no analytics, no advertising.
No telemetry or crash reporting.
No remote API calls. The bundled libraries execute entirely locally.
No third-party tracking pixels or beacons.
No reading of pages other than .md, .markdown, .mdown files in the declared content-script match patterns.

User-data categories

None of the following categories are collected, used, or transferred by this extension:

Personally identifiable information
Health information
Financial and payment information
Authentication information
Personal communications
Location
Web browsing history
User activity
Website content

In addition, the developer certifies that user data is not sold or transferred to third parties outside the approved use cases, is not used for purposes unrelated to the extension's single purpose (rendering Markdown locally), and is not used to determine creditworthiness or for lending purposes.

Permissions

The extension declares only content_scripts matching .md URLs (HTTP, HTTPS, and file://). It does not request tabs, history, storage, webRequest, or any other browser API permission.
