1. Free packages

They can be used at no cost in personal or commercial projects, including ones that are sold or offered as a service.
They may not be redistributed as part of a public library, framework, template or development tool, nor sold separately.

2. Packages under a commercial license

Using them in any project (personal or commercial) that is published or put into production requires a valid AstrolUI license.
They can be tried without a license only in local development and test environments that don't serve end users.
License terms (projects, developers, duration, updates and price) are agreed in writing; request one at [email protected].
The NuGet repository will soon require credentials to download these packages.

Source code: not available. Decompiling, reverse engineering or modifying the packages is not allowed.
Intellectual property: all rights to the code, design and functionality of the Astrol. packages belong to Asley F. Cruz. Use grants no rights beyond those stated here.
Support: not guaranteed for the free packages; for commercial ones it is what each license states.
Liability: the packages are provided "as is", without warranties of any kind. The author is not liable for direct or indirect damages arising from their use.
Third-party components: Astrol.Component.Charts includes ApexCharts 3.50 (MIT license) and Astrol.Component.PDFViewer includes PDF.js (Apache 2.0 license); those parts are governed by their own licenses.
