Terms of use
By using Sketch Hour you agree to these terms. They’re short.
Last updated 5 November 2026
Using Sketch Hour
Sketch Hour is free to use for practicing and studying drawing.
Your references
You’re responsible for the images you add. Only add images you’re allowed to use for study. Sketch Hour doesn’t claim any rights to them, and they stay in your browser.
Content from other sites
Images from Pinterest, FilmGrab, MapCrunch and other sites belong to their owners and are covered by those sites’ terms. Sketch Hour isn’t affiliated with or endorsed by them.
The museum references in the curriculum are works the Art Institute of Chicago has released as public domain (CC0). The rendered references were made for Sketch Hour.
No guarantees
Sketch Hour is provided as is. Features can change or stop working, including the Pinterest boards, which depend on Pinterest. To the extent the law allows, we aren’t liable for lost references or practice data, so keep copies of images that matter to you.
