Scores are open, and most of what you write isn't. Once a round is done, anyone holding its link can read the card, with no login, and the captions golfers wrote on it unless the round is private, kept out of friends' feeds or hiding its scores while it's played; while it's being played, only people connected to someone on it can see it. A finished round shows up in Home for anyone who's friends with a player on it, unless that player turned off Show in friends' feeds for it: then it's still there for anyone who looks. Posts go to friends unless you pick Everyone or Only me. Your email, phone, and birthday reach your friends only if you choose to share them, and your GHIN number stays yours alone. You can export everything you own as JSON or delete your account in-app; your rounds stay on your buddies' cards, with no account behind them.
