Actually, it says so clearly here 🙂 https://github.com/TandoorRecipes/recipes#all-the-must-haves
"This application is meant for people with a collection of recipes they want to share with family and friends or simply store them in a nicely organized way. A basic permission system exists but this application is not meant to be run as a public page."
@ruihildt right, it's documented as such at https://github.com/TandoorRecipes/recipes#license as well. My understanding is it's OK to selfhost but not resell tandoor for commercial stuff or host it for others (in the spirit of the author's current state of mind).
