Retro is built to help you share meaningful moments with friends while keeping you in full control of your privacy. Your account is set to private by default, which means only the friends you’ve added can see your posts and activity. Anyone who isn’t in your friends list won’t have access to your shared content.
How far back can my friends see my posts?
Your daily or weekly photo posts are also visible exclusively to your friends and remain available for up to 4 weeks before they automatically expire, Unless you give them a key, in which they can see your posts beyond 4 weeks.
