SF Pro Rounded font is it a universal font

Gemini Says:

SF Pro Rounded is not a universal font in the same way that fonts like Arial or Times New Roman are. Here’s why:

• Apple-Designed Font: SF Pro Rounded is part of the San Francisco font family, which was designed by Apple Inc. specifically for its operating systems (iOS, iPadOS, macOS, tvOS, watchOS) and products.
• Licensing Restrictions: Apple's licensing agreements generally restrict the use of SF Pro fonts, including SF Pro Rounded, for the design and development of applications only for Apple’s platforms. This means you typically cannot use it freely for commercial purposes outside of Apple’s ecosystem, such as on websites or applications for other operating systems (Windows, Android, etc.), without violating the license.

Important!

• The UI fonts for Apple, specifically SF Pro, aren't consistently available outside of WebKit-based browsers on macOS.
• The UI fonts won't work on non-Apple operating systems.
