Markdown Viewer with Mermaid
Last updated: August 22, 2026
Markdown Viewer with Mermaid does not collect personal information and does not send document contents or usage data to the developer.
Local Processing
Markdown files you open are processed locally in your browser to render the page, diagrams, table of contents, search, and editor. Preferences such as theme, language, and toolbar layout are stored with Chrome's storage APIs and may sync with your Google account only if you have Chrome Sync enabled.
Data Sharing
We do not sell or share user data. To view local files, you must enable "Allow access to file URLs" in the extension's details; those files remain on your device.
