MarkdownTrellis Clip Privacy Policy

Effective: 2026-11-08 / Last updated: 2026-11-11

MarkdownTrellis Clip (the "extension") is a Google Chrome extension for pasting Markdown, checking it, making light edits, and copying it as Markdown or as formatted text. This policy describes how the extension handles information.

Information handled and why

  • Text you enter: Markdown you paste or type is used only inside the extension's work tab, to show the preview, to apply the formatting buttons, and to copy or download it. The text, selection, undo history and preview are not stored anywhere. They are discarded when you close or reload the tab, or click Clear.
  • Clipboard: the extension writes to the clipboard only when you click Copy Markdown, Copy Formatted or Copy Selection Formatted. It never reads the clipboard automatically. Pasting is Chrome's normal paste that you perform with Ctrl+V or similar. When "Paste formatted text" is on, the formatted (HTML) text in what you paste is read inside the work tab to convert it to Markdown. The converted text is handled like the rest of your text and is never saved or sent.
  • Downloads: only when you click Download, the text is saved to your computer as a .md file, following Chrome's download settings.
  • Settings: only when you choose "Save as the default for new tabs" in the Extra syntax dialog, the list of extra syntax names to enable (for example, alerts and footnotes) is saved in Chrome's extension storage (chrome.storage.local) and used when a new work tab opens. In addition, when you click OK in Paste settings…, whether to paste formatted text (on or off) is saved in the same storage. Neither contains your text or any website information.

Sending information

The extension does not send your text or settings to the developer or to any third party. It has no server communication, analytics or advertising, and the extension page is restricted so that it cannot connect to external sites. The preview does not load images from the internet or from your computer.

The extension does not read the content of websites you visit (it has no permission to access websites).

Only when you click a link in the preview (http, https or mailto) does it open in a new tab or your email app. Communication with the linked site takes place in that page or app.

Content the extension writes to the clipboard is handled by the app or service where you paste it. If you use your operating system's clipboard history or sync, it is also handled according to those settings.

Retention and deletion

Because the text is not stored, there is nothing to delete. To clear the saved default for extra syntax, click Clear all in the Extra syntax dialog, select "Save as the default for new tabs", and click OK. To turn off pasting formatted text, uncheck it in Paste settings… and click OK. Removing the extension from Chrome also removes the saved settings. Downloaded files remain on your computer; delete them yourself when you no longer need them.
