Frequently asked questions
The OFL lets you use the font anywhere - websites, apps, logos, print, products and client work - free of charge, commercially or not. You can also modify the font and redistribute it, as long as derivatives stay under the OFL and don't reuse any reserved name.
No attribution is required to simply use an OFL font in a document, website or product. Only when you redistribute the font files themselves must the copyright and license notices travel with them. A credit is always appreciated, never required.
Yes - anything you design with it (logos, books, merchandise, apps) can be sold freely. The one thing the OFL forbids is selling the font files by themselves; they must be free or bundled with something else.
