If it is really just for personal use (i.e. not making any money off it, not even indirectly like YouTube ads), you are welcome to use the maps as long as the logo is visible and you properly credit us. A properly credited artwork has both the artist's name and the source of the picture with a clickable url: Artist/credit: Robert Szucs, source: www.grasshoppergeography.com Tagging us on social media would also do the trick (and we thank you for that), but a URL for source is a must. If you are unsure, or you'd like to use our maps for a commercial project, please get in touch, we are happy to discuss it. There are some occasions when you cannot use our work, though. We strictly prohibit using our maps in activities (incl. speeches, posts, videos, etc) that promote or foster discrimination on the basis of race, religion, gender, marital status, familial status, national origin, age, mental or physical disability, sexual orientation, gender identity, source of income or other protected status. Please don't use our maps for political purposes either, without asking for permission first.
