2. License Grant

Subject to the terms and conditions of this Agreement, Swing-UI.com ("Licensor") grants you a limited, non-exclusive, non-transferable, non-sublicensable license to use the Software solely in accordance with this Agreement and the license tier you have purchased or obtained.

2.1 Free License

Permitted for personal, non-commercial use only.
Limited to the UI components explicitly designated as "Free" in the Licensor's documentation or product listings.
No support is guaranteed.
2.2 Personal License
A one-time license fee grants you the right to use most UI components for personal, non-commercial use.
The following components are excluded from the Personal License: InternalWindow and SplitView. Access to these components requires a Commercial License.
May not be used in any product or service offered for sale or subscription.
2.3 Commercial License

All rights not expressly granted in this Agreement are reserved by the Licensor.

3. License Scope and Usage Restrictions

3.1 Single-Developer Use

Each license is tied to one (1) individual developer. That developer may use the Software across their own personal machines, local virtual machines, and CI/CD pipelines that build their own licensed projects. Use of the Software by multiple developers within a team or organization requires a separate license per developer, unless explicitly authorized in writing by the Licensor.

3.2 Runtime Environments

The Software is designed to run on supported Runtime Environments (Node.js, Bun, and Deno 2) in runtime version as specified in documentations. Use of the Software on any other runtime or platform is at your own risk and is not supported by the Licensor.

3.3 Package Registries and Distribution Channels

You may install the Software via supported package registries (e.g., npm, JSR) for your own licensed use. You may not:

Publish, re-publish, or upload the Software (or any modified version thereof) to any package registry or distribution channel as a standalone package.
Distribute the Software under a different package name or identifier for the purpose of circumventing licensing restrictions.
Make the Software available for download or use by others outside of your own bundled application.
3.4 No Sharing or Transfer
You may not sell, rent, lease, sublicense, share, assign, or transfer your license or the Software to any third party. This includes sharing access credentials, license keys, or activation tokens.
3.5 No Circumvention or Tampering
You may not modify, disable, bypass, tamper with, or otherwise interfere with any license validation, activation, usage tracking, or protection mechanisms implemented in the Software. Distribution or use of modified versions of the Software designed to bypass licensing is strictly prohibited.

4. Distribution and Bundling Rules

4.1 Permitted Bundling (Free and Personal Licenses)
