Last updated: May 17, 2026 · Effective: May 17, 2026
This page is both the license agreement for the Morion desktop app and the terms of service for morion.ai. One document, because the rules are simple.
You own your notes. Morion stores them as a local data file and markdown on your disk. They're yours. You can export, copy, or delete them anytime. We never receive them.
Free and open source. Morion is free and open source under Apache 2.0 — the full notebook, kanban, MCP sync, Mo work packets, and the Auto-code harness are all included. There's no paid tier, no subscription, and no license key. Mo and Auto-code run on your own LLM provider key. The source is on GitHub; the Morion name and logo are trademarks.
Don't do the obvious bad things — the code is Apache-2.0, but don't ship a fork under the Morion name or logo, and don't use it to break the law.
Software is provided as-is. We back Morion, fix bugs, and ship updates — but we can't promise it's defect-free, and our liability is capped at US$50 (§10).
The rest of this page is the careful, legally-useful version of the same thing.
"Morion," "we," and "us" refer to the makers of the Morion desktop application and this website. "You" refers to the person or entity using Morion.
By downloading, installing, or using Morion — or by using the morion.ai website — you agree to these Terms. If you don't agree, don't install the app and don't use the site. If you're using Morion on behalf of a company or other organisation, you represent that you have the authority to bind that organisation to these Terms.
These Terms should be read alongside our Privacy Policy, which describes what limited data we and our subprocessors see.
Morion's source code is released as open source under the Apache License 2.0, published at github.com/miksushko/morion-oss. Your rights to use, copy, modify, and redistribute the code are governed by that license. Where the Apache 2.0 license and these Terms differ on the code, the Apache 2.0 license controls for the code.
These Terms additionally cover your use of the official signed builds we distribute and of morion.ai. The Apache 2.0 license does not grant any trademark rights: the Morion and Mo names, the logo, and the branding remain ours. See the repository's TRADEMARK.md and §3.
Your notes and other content you create in Morion are yours. This license covers the software, not your data. See §5 for the details on your content.
The Apache 2.0 license is permissive — you may use, modify, fork, and redistribute the code under its terms. The limits below are about our brand and lawful use, not about the code itself. You agree not to:
You may use any MCP-compatible AI client with Morion. You may back up your data file wherever you want. You may read, build, and contribute to the source on GitHub. If you send us feedback, bug reports, or feature ideas, you grant us a non-exclusive right to use them without obligation to you.
Everything is free. Morion is free and open source. The full notebook, full MCP access, unlimited notes and kanban boards, per-folder and per-note MCP permissions (visible / create / update / delete), Mo work packets and in-app chat, and the Auto-code build/review workflow harness are all included for everyone. There is no paid tier, no subscription, no license key, and no checkout.
Your LLM provider. Mo and Auto-code run on the LLM provider you connect via API key (e.g. OpenRouter, OpenAI, Anthropic, Groq, or a local Ollama). You are responsible for the relationship with that LLM provider — their terms, their billing, their data-handling. Morion is not in the path of those LLM calls; we don't see prompt content. There is no hosted Morion model.
Builds and source. You can run the official, code-signed builds we distribute (see downloads), or build from source under Apache 2.0. Both are free. The Morion name and logo remain trademarks (§2, §3).
Feature changes. We may add, change, or remove features in future updates. We will not intentionally remove something you've come to rely on without a reasonable replacement or advance warning in the changelog or on GitHub. The current state of in-progress capabilities (for example, parts of Auto-code) is reflected in the app and the source.
Every note, tag, folder, task, and attachment you create in Morion is yours. You retain all intellectual property rights in that content. We claim no ownership, license, or right to use it for any purpose — including not for training, analytics, or product improvement — because we never receive it.
Morion stores your content in a local data file on your disk. We do not operate a server that hosts it. This has two consequences you should understand:
If you connect Morion to an AI client via MCP (Claude Code, Codex, Gemini Antigravity, Cursor, Cline, Zed, etc.), that client may read or write to the notes you permit. You are responsible for which clients you connect and which folders or boards you grant them access to. See our Privacy Policy §3 for how that flow works.
If you enable Mo or run Auto-code, the task-scoped work packet from the folder Mo or Auto-code is working on is sent directly from your machine to whichever LLM provider you connect (OpenRouter, OpenAI, Anthropic, Groq, or local Ollama) — we are not in that path. Mo never sees your whole notebook; folders you have hidden from AI are invisible to Mo too. Full data flow in our Privacy Policy §7.
Morion integrates with a small number of third-party services so it can ship updates, run optional LLM calls, and measure aggregate traffic on the marketing site. Their roles are described in full in our Privacy Policy §§7-8. When you use those integrations, their terms also apply:
We are not responsible for the availability, content, or practices of third-party services, except that we choose them carefully and document exactly what they see.
Morion ships updates periodically — security fixes, bug fixes, and new features. By installing the app, you consent to the app checking for and installing updates automatically. Updates are delivered as signed macOS .dmg packages hosted on GitHub Pages and verified by the operating system before install.
You can disable automatic update checks in the app's settings. We strongly recommend leaving them on — we use the update channel to ship security patches, and we will not ship an update that silently changes your data format or deletes your notes.
We may add, change, or remove features in future updates. We will not intentionally remove something you've come to rely on without a reasonable replacement or an advance warning in the changelog or on GitHub.
"Morion" and the Morion logo are our trademarks. You may refer to Morion in reviews, comparisons, tutorials, and screenshots in the ordinary course — we're delighted when people write about Morion. You may not use our name or logo in a way that implies endorsement, partnership, or affiliation unless we've agreed in writing.
If you send us feedback, bug reports, or feature requests (for example via hello@morion.ai or the waitlist form), you grant us a perpetual, irrevocable, royalty-free licence to use that feedback in the product, with no obligation to compensate you or keep it confidential. You will not expect payment, credit, or a response.
The following section is written in emphatic language because law requires it to be visible. Please read it.
MORION AND THE MORION WEBSITE ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, TITLE, UNINTERRUPTED SERVICE, ERROR-FREE OPERATION, OR ACCURACY.
Nothing Morion does constitutes legal, medical, financial, or other professional advice, even when an AI system is reading your notes.
Some jurisdictions do not allow the exclusion of certain warranties, so some of the above may not apply to you. In those jurisdictions, our warranties are limited to the minimum duration and scope permitted by law.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, MORION WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES — INCLUDING LOSS OF DATA, LOSS OF PROFITS, LOSS OF GOODWILL, BUSINESS INTERRUPTION, OR COST OF SUBSTITUTE GOODS OR SERVICES — ARISING OUT OF OR RELATING TO YOUR USE OF MORION, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
MORION IS PROVIDED TO YOU FREE OF CHARGE. OUR TOTAL AGGREGATE LIABILITY TO YOU FOR ALL CLAIMS RELATING TO MORION IN ANY 12-MONTH PERIOD WILL NOT EXCEED US$50.
Nothing in these Terms limits or excludes any liability that cannot legally be limited or excluded — including liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or under any non-excludable consumer protection law that applies to you.
You are responsible for how you use Morion and for the content you put into it. If a third party brings a claim against us because of content you stored in Morion or the way you used the app in breach of §3, you agree to defend us against that claim and pay the damages, costs, and reasonable legal fees a court finally awards against us — to the extent permitted by law and reduced by any fault of our own.
You can stop using Morion at any time. Delete the app and your data file and you're done. There is nothing to cancel — Morion is free.
We can terminate the rights granted under these Terms if you materially breach them — for example, by misusing the Morion name or logo (§3), or by using Morion for illegal purposes. Your rights in the source code under Apache 2.0 are governed by that license. Where the breach can be fixed, we will notify you and give you a reasonable opportunity to fix it before terminating.
On termination: the license in §2 ends. Sections that by their nature should survive (§3 restrictions, §5 your content, §9 warranty disclaimer, §10 liability, §11 responsibility, §13 governing law) survive termination. Your notes on your disk are unaffected — they were always yours.
These Terms are governed by the laws of the Republic of Lithuania, excluding its conflict-of-laws rules and excluding the UN Convention on Contracts for the International Sale of Goods. Disputes that we can't resolve by talking will be brought exclusively in the competent courts of Vilnius, Lithuania.
If you're a consumer resident in the European Economic Area, the United Kingdom, or Switzerland, the above does not deprive you of the protection of any mandatory consumer-protection law of your country of residence — you may bring a claim in the courts of your home country if your local law says you can. EU consumers may also use the European Commission's Online Dispute Resolution platform, though we'd prefer you email us first at support@morion.ai — we read every message.
We may update these Terms from time to time — to reflect product changes, new integrations, or legal requirements. When we do, we'll update the "Last updated" date at the top and, for material changes, notify users on the website and — where we have their email — by email at least 30 days before the change takes effect.
Continued use of Morion after a change means you accept the revised Terms. If you don't accept them, stop using Morion and delete it.
Whole agreement. These Terms, plus the Privacy Policy, are the entire agreement between you and us about Morion. They replace any prior understanding.
Severability. If any part of these Terms is held unenforceable, the rest stays in force.
No waiver. If we don't enforce a provision on one occasion, that doesn't mean we've waived the right to enforce it later.
Assignment. You can't transfer your rights under these Terms without our written consent. We may transfer ours as part of a corporate reorganisation, acquisition, or sale of all or substantially all of our assets — your rights won't be diminished.
Force majeure. Neither party is liable for delay or failure to perform to the extent caused by events beyond reasonable control (outage of a third-party provider, natural disaster, network failure, act of government).
