 #### Toot Privacy
 
 Toot privacy is handled independently of account privacy, and individually for each toot. The four tiers of visibility for toots are Public (default), Unlisted, Private, and Direct. In order to select your privacy level, click the ![Globe icon](screenshots/compose-privacy.png) globe icon. Changes to this setting are remembered between posts, i.e. if you make one private toot, each toot you make will be private until you change it back to public. You can change your default post privacy under preferences.
