# Looop Engine License

**Version 1.0 — 2026-07-10**

This license covers the **Looop Engine**: the software bundle you download
through the Looop CLI after signing in — game libraries, the platform layer,
the multiplayer room server, and the accompanying craft documentation
(together, the "Engine"). It is written to be read by humans (and their AI
agents); the short version is:

> **Read it, learn from it, modify it, and use it to build and publish games
> on Looop. Your games are yours. The Engine stays ours, stays on Looop, and
> may not be redistributed or used to build something that competes with
> Looop.**

## 1. Definitions

- **"Looop Platform"** — the services operated by Looop at and around
  `play.looop.games`, including publishing, hosting, multiplayer, identity,
  and platform APIs.
- **"Your Game"** — a game you develop for the Looop Platform, consisting of
  the code and assets you (or your tools) author. Files you copy or adapt
  from the Engine — including `overrides/` copies of Engine modules — remain
  part of the Engine, not Your Game.
- **"You"** — the holder of the Looop account that accepted this license.

## 2. License grant

Subject to this license, Looop grants you a personal, non-exclusive,
non-transferable, revocable license to **download, read, run, and modify the
Engine solely to develop, test, and publish games on the Looop Platform**.
This grant is tied to your Looop account and each Engine download is made
under it.

Publishing and monetizing Your Game on the Looop Platform is expressly
allowed — including commercially. Learning from the Engine's code and
documentation is expressly allowed.

## 3. Your Game is yours; the Engine is ours

You keep all rights in Your Game. Looop claims no ownership of the code or
assets you author, beyond the hosting and distribution permissions you grant
by publishing on the Looop Platform (governed by the platform's terms).

The Engine — including any copy, portion, or modification of it, wherever it
lives — remains the property of Looop. Modifying the Engine (for example via
`overrides/`) is allowed for use in Your Game on the Looop Platform, and does
not transfer any ownership to you.

## 4. Restrictions

Except as needed for the use allowed in section 2, you may not:

1. **Redistribute the Engine** — publish, share, sublicense, sell, or host
   the Engine or any substantial portion of it (code or documentation)
   outside the Looop Platform, in source or bundled form, including inside a
   game distributed anywhere other than the Looop Platform.
2. **Use it off-platform** — use the Engine or its components to build,
   power, or ship software that is not a game for the Looop Platform.
3. **Compete with Looop** — use the Engine, its code, or its documentation to
   build or operate a product or service that competes with the Engine or
   the Looop Platform.
4. **Remove notices** — strip copyright, license, or attribution notices from
   the Engine.

## 5. Termination

This license ends automatically if you materially breach it, or when your
Looop account is closed. On termination you must stop using the Engine and
delete your copies; games already published on the Looop Platform are
governed by the platform's terms. Looop may revoke access to Engine downloads
at any time; versions you legitimately downloaded remain licensed for the use
allowed in section 2 while your account is in good standing.

## 6. No warranty; limitation of liability

The Engine is provided **"as is"**, without warranty of any kind, express or
implied, including merchantability, fitness for a particular purpose, and
non-infringement. To the maximum extent permitted by law, Looop is not liable
for any damages arising from the Engine or its use, and Looop's total
liability under this license is limited to the amount you paid for the Engine
(zero, today).

## 7. Changes

Material changes to this license get a new version number and are accepted
the same way this one was — at sign-in approval. The version you accepted
governs the downloads made under it.

*Accepted at the `/activate` approval step ("I agree to the Looop Engine
License"). A copy ships as `LICENSE.md` inside every Engine download.
