Buril

Legal

Terms of Service

Version 2.0 · 19 August 2026

Buril is proprietary software licensed under a paid subscription. The source is closed and confidential.

Everything Buril generates for you is yours — scripts, prefabs, scenes, configuration. No copyright of ours, no license of ours, including work you deliver to clients and charge for. If you stop paying, you stop using Buril: you do not lose your game.

1. Definitions

Licensor — the copyright holder of Buril and its sole owner.

Software — the Buril Unity Editor bridge, its tool catalog, the MCP connector and relay, the desktop extension package, accompanying documentation, and any updates the Licensor makes available. Third-party components listed in the attribution notices are not part of the Software for the purposes of Sections 3 and 4; see Section 7.

You — the individual or legal entity that has accepted these terms.

Seat — one named individual authorized to use the Software. Seats are not concurrent-use licenses and may not be shared, pooled, or rotated among people.

Subscription — a current, paid entitlement issued by the Licensor that identifies your tier and your number of Seats.

2. Grant of license

Subject to your Subscription being current and to every limitation in this document, the Licensor grants you a non-exclusive, non-transferable, non-sublicensable, revocable license to:

  1. Install and run the Software on machines controlled by you or your organization, for as many Seats as your Subscription covers.
  2. Use the Software to develop, test, and ship your own games, tools, and other projects — including work you deliver to clients and charge for.
  3. Keep the output. Everything the Software produces for you is yours. The Licensor claims no ownership of, and no license to, your project or its output.

This is a license to use, not a transfer of ownership.

3. Restrictions

You may not:

  1. Redistribute the Software, in whole or in part, in source or binary form, whether or not for a fee. This includes publishing it, mirroring it, bundling it into another product, or including it in a repository, package, or asset others can obtain.
  2. Host the Software as a service for anyone outside your organization, whether paid or free.
  3. Reverse engineer, decompile, or disassemble the Software, or attempt to derive its source code, except to the extent this restriction is unenforceable under law that applies to you.
  4. Circumvent licensing, metering, or authentication, including modifying the Software to run without a valid Subscription, or sharing Subscription credentials or bridge tokens outside your Seats.
  5. Build a competing product using the Software, its source code, its tool catalog, or its documentation as a basis or reference.
  6. Remove or obscure copyright notices, license notices, or attribution.
  7. Transfer or assign this license, including by merger or acquisition, without the Licensor's prior written consent.

If you have access to the source code (as an employee, contractor, or under a separate written agreement), it is confidential information. You may read and modify it for your own internal use under a current Subscription; you may not disclose, publish, or share it.

4. Ownership

The Software is licensed, not sold. The Licensor retains all right, title, and interest in and to the Software, including all intellectual property rights. All rights not expressly granted in Section 2 are reserved.

Feedback you send the Licensor (bug reports, feature requests, suggestions) may be used freely and without obligation or compensation to you. This does not give the Licensor any rights to your project, your code, or your assets.

5. Your data

The Software runs locally inside your Unity Editor. Your project files, source code, and assets stay on your machine. What the Software transmits, and to whom, is described in the Privacy Policy.

The Licensor does not train models on your project content.

6. Term and termination

This license runs for as long as your Subscription is current.

It terminates automatically if you breach Section 3. It also terminates when your Subscription lapses, expires, or is cancelled.

On termination you must stop using the Software and delete all copies, including any source code in your possession.

Everything the Software produced for you before termination remains yours, and remains usable, without restriction. You do not lose your game because you stopped paying for the tool.

Sections 3 (last paragraph), 4, 8, 9, and 10 survive termination.

7. Third-party components

The Software includes third-party components — 34 under the MIT License and 5 under Apache License 2.0 — listed with their notices in the attribution documentation. Those components remain governed by their own licenses, not by this one. Nothing in this document restricts any right you have in those components under their original terms.

8. No warranty

THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. THE LICENSOR DOES NOT WARRANT THAT THE SOFTWARE WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT IT WILL MEET YOUR REQUIREMENTS.

The Software modifies files in your Unity project. Keep your project under version control and keep backups. The Licensor is not responsible for lost or damaged work.

9. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE LICENSOR WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, OR BUSINESS, ARISING OUT OF OR RELATED TO THE SOFTWARE, WHETHER IN CONTRACT, TORT, OR OTHERWISE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

THE LICENSOR'S TOTAL AGGREGATE LIABILITY WILL NOT EXCEED THE AMOUNT YOU PAID FOR THE SUBSCRIPTION IN THE TWELVE MONTHS PRECEDING THE CLAIM.

Some jurisdictions do not allow these exclusions; in those places they apply only to the extent permitted.

10. General

Entire agreement. This document, together with your Subscription terms, is the entire agreement between you and the Licensor about the Software, and supersedes the Buril Sustainable Use License v1.0 and any prior understanding.

Severability. If any provision is held unenforceable, the rest stays in effect.

No waiver. A failure to enforce any provision is not a waiver of it.

Changes. The Licensor may issue new versions of these terms for new releases. The version shipped with the release you are using governs that release; a new version does not retroactively change the terms of a release you already have.

11. Contact

Licensing, enterprise terms, and anything this document doesn't answer in writing — ask before you deploy. Good-faith questions get a written answer you can rely on.
