IntegralCam ships fifteen font files across fourteen typeface families. Hanken Grotesk sets the interface, Space Mono sets counters and technical labels, and the handwriting faces write your captions: Permanent Marker, Reenie Beanie, Homemade Apple, Caveat, and Shadows Into Light — joined by Yomogi, Klee One, and Zen Kurenaido for Japanese, Gaegu and Nanum Pen for Korean, and Neucha and Marck Script for Russian.

Twelve families are used under the SIL Open Font License 1.1. Permanent Marker and Homemade Apple, both by Font Diner, Inc., are used under the Apache License 2.0. The full license text for each family is below.
