Terms of Service

Last updated: March 2026

1. License to Use

RakuAI Inc. grants you a non-exclusive, worldwide, royalty-free license to use the Raku Engine runtime for both commercial and non-commercial game development. The Free tier includes 8 templates and limited resource allocation. The Pro tier ($14.99/month) includes all features, templates, and expanded resource limits.

2. User-Generated Content

You retain full ownership of all games, .raku files, and creative content you produce using the Raku Engine. RakuAI Inc. does not claim any ownership, copyright, or license over your creations. You may distribute, sell, or modify your games without restriction, subject to the acceptable use policy below.

3. AI-Generated Content Responsibility

Games created with the Raku Engine may include AI-generated content at runtime, including NPC dialogue, dynamic difficulty adjustments, and procedural content. You are responsible for the content your games generate, including compliance with platform content ratings (ESRB, PEGI, etc.) and storefront policies (Steam, Xbox, etc.). The ai_disclosure system in every .raku file helps you declare AI usage for platform compliance.

4. Acceptable Use

You may not use the Raku Engine to:

  • Create malware, spyware, or software designed to harm users
  • Circumvent content rating systems or storefront policies
  • Reverse engineer the runtime binaries (the .raku file format is open; the engine internals are proprietary)
  • Redistribute the runtime binaries under a different name or brand
  • Use the engine in violation of applicable laws

5. Limitation of Liability

THE RAKU ENGINE RUNTIME IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. RAKUAI INC. SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF YOUR USE OF THE SOFTWARE. Our total liability to you shall not exceed the amount you paid for the Pro subscription in the 12 months preceding the claim.

6. Termination

Free tier access may be revoked if you violate the acceptable use policy. Pro subscriptions may be terminated for ToS violations with 30 days written notice. Upon termination, you retain all .raku files and game content you have created. The runtime will continue to function for games already distributed.

7. Governing Law

These terms are governed by the laws of the State of Washington, United States. Any disputes shall be resolved in the courts of Washington State.
