Review the terms for fonts you distribute

← All articles

OFL font delivery, including in an SDK, requires review of license and copyright inclusion, standalone sales and any Reserved Font Names. A listed font alone does not prove redistribution.

Read about OFL-1.1 font terms

If you redistribute the font, include copyright and OFL text, do not sell it alone, and respect any Reserved Font Names. Otherwise, acknowledge after confirming no font redistribution.

When this review appears

Shown for OFL fonts in Distributed binary, Library or SDK, and Mixed. Actual duties depend on font redistribution; renaming depends on Reserved Font Names and permission.

Before you acknowledge

  1. Check whether font files actually ship with your product or SDK. If they do, include the copyright notice and OFL text and do not sell the font on its own.
  2. If you modify the font, check whether upstream declares Reserved Font Names. A modified font must avoid those names unless the copyright holder grants permission to use them.
  3. Acknowledge after meeting the applicable OFL terms, or after confirming that you do not redistribute the font.

Reserved Font Names are names expressly declared by the copyright holder, not every original font name or trademark. If no Reserved Font Name is declared, this condition does not require renaming a modified font. If a name is reserved, permission from the copyright holder may allow its continued use.
