The Twitter marks include, but are not limited to, the Twitter name, Twitter logo, the term “Tweet” and any word, phrase, image, or other designation that identifies the source or origin of any Twitter product. Always capitalize the T in “Twitter,” as well as all noun and verb versions of “Tweet” and “Retweet.”
Never use Twitter logos or icons as your own. Please don’t incorporate Twitter’s marks, in whole or in part, in the name of your company, product, service, website, domain name, application, or website.
Remember to always be clear that it’s about Twitter, not by Twitter. Please name your books and publications something unique, and do not incorporate Twitter’s marks (Twitter, Tweet, Retweet, and Twitter logo) in the title or cover.
A product branded with the Twitter name or logo is a reflection of Twitter. Unless the Twitter logo is locked up with a #Hashtag or @Username, or you’re using it with other social media icons, we don’t allow others to make, sell, or give away anything with our name or logo on it.
