Gister is set in three open typefaces, all released under the SIL Open Font License 1.1. The license lets us bundle and use them freely; it does not let anyone sell the fonts on their own.

The full license text for each face ships inside the app bundle (OFL-Syne.txt, OFL-Karla.txt, OFL-DMMono.txt).
