### Permission Terms by Use

| Use | Status | Note |
| :--- | :--- | :--- |
| Commercial work | Allowed | Whatever you make with the font is yours; the licence covers the font files. |
| Logo or wordmark | Allowed | A logo is a document made with the font; the licence sets no limit on it. |
| Website (@font-face) | Allowed, with conditions | Serving the file to browsers is redistribution: the copyright notice and licence travel with it, and the font file's own metadata counts. |
| App or game bundling | Allowed, with conditions | Bundle it in free or paid software; ship the copyright notice and licence with it. |
| Modify the font | Allowed, with conditions | A modified font stays under the OFL and must not use a Reserved Font Name (each font page lists its own). |
