How far can I use a Free license?
The free license is similar to desktop license for anyone who needs fonts (.otf) installed on their Windows or Mac OS machine but limited to tests (solely evaluation + internal tests) and non-commercial use. The free fonts glyph set is more limited than Std or Pro fonts but already provide enough glyphs for usual projects. Any others use require the purchase of a desktop license, artwork license, ePub license, App license, server license, broadcast license, web license.
