Terms of use.
Imark is free, open source, and made by one person. These terms cover the app, this site, and what happens if something goes wrong. They are short because the arrangement is simple.
Updated
The short version
Download Imark and use it for anything, at home or at work. You pay nothing and you sign up for nothing. In return, it comes with no warranty and no promise of support: one person maintains it, in his own time.
Using Imark or this site means you accept what follows.
The licence
Imark is released under the MIT licence. You can use, copy, change, and redistribute it, including in something you sell, as long as the copyright notice and the licence text travel with it.
The licence covers the code. It does not hand over the name or the icon — if you ship a build of your own, give it your own name.
Imark bundles other people’s open source, all of it permissive. THIRD-PARTY.md lists every package and its licence, and the same list ships inside the app under Imark > About Imark.
Where the download comes from
Every copy of Imark comes from the releases page on GitHub, or from the Homebrew tap. The disk image is signed with an Apple Developer ID and notarised by Apple, which is why it opens without a Gatekeeper warning.
If you found Imark on a download site, in a torrent, or anywhere else, it did not come from us and there is no way for us to vouch for what is inside it.
Your files stay your responsibility
Imark reads documents; it does not edit them. Comments are the exception: a note you write is saved into the Markdown file itself. Imark writes it to a temporary file and moves that into place, refuses to save at all if the document changed on disk since it read it, and keeps the last ten states so ⌘Z can undo any of them.
None of that is a backup. Keep your documents in version control or backed up, the way you would with any app that writes to them. If Imark ever damages a file, open an issue — that is the one bug worth interrupting everything else for.
Coding agents
Imark can hand a document back to a coding agent with your notes in it. The whole handshake is two small files on your own Mac, and the agent — Claude Code, Codex, or whatever else you run — is somebody else’s software under somebody else’s terms. What it does after you press Approve or Send Back is between you and it.
The skill guide explains how the review works before you install anything.
No accounts, nothing to cancel
There is no sign-up, no subscription, no trial, and no payment, so there is nothing to cancel and no receipt to keep. Uninstalling is dragging Imark to the Trash.
Imark collects nothing about you, which the privacy page goes through in detail.
No warranty
In the words of the licence, Imark is provided “as is”, without warranty of any kind, and its author is not liable for any claim or damage arising from it. In plain words: it is free software before version 1.0, written by one person, and you use it at your own risk.
That is the legal position, not the intention. Bugs get fixed and issues get answered — see what Imark is and is not for the honest shape of the project.
This site, and changes to this page
The words, screenshots, and recordings on imarkmd.com belong to their author. The commands and code snippets in the guides are there to be copied and used.
These terms can change as the app does. There is no mailing list to notify, so the date at the top of this page is the record: if it moved, so did the text.
Imark is made in Portugal, so Portuguese law applies to these terms. Nothing here takes away a consumer right you hold where you live.
Questions go to the issue tracker, where a person reads them.
