Font licenses
What each license type allows
Reference
'Downloaded free' ≠ 'can use': trial fonts in commercial logos — courts punish clients, not designers. Google Fonts (OFL) is a safe default for commercial work. When buying: check whether a separate web/app license is needed. For clients — pass the font name, not the file.
SIL OFL
Allows
Commercial ✓, web ✓, apps ✓, modification ✓
Limits
Can't sell the font alone; modified versions must use OFL + new name
