In general, you will need to purchase a license for proprietary fonts, which are fonts that are owned by an individual or company and are subject to copyright law.

Proprietary Fonts

These fonts are typically developed by commercial font foundries or individual designers, and they are typically not available for free download. If you want to use a proprietary font in your project, you will need to purchase a license from the font's creator or an authorized distributor.

Open Source Fonts

On the other hand, many fonts are available for free use under open source or free licenses. These fonts are typically available for download from a variety of websites, and they can be used for personal or commercial projects without the need to purchase a license.

Best Practice

In general, it's a good idea to check the license for any font that you plan to use in your project, whether it is a proprietary or open source font. This will help you ensure that you are using the font legally and appropriately.
