The dated record your companions quietly keep as you share your days — plus anything you write in yourself. Each entry stays with the companion you told it to; entries you add here can be recalled by any of them. Edit fixes an entry's wording in place; Forget removes it for good.
Dated today, in your own words. Any of your companions can recall entries you add here.
Each companion keeps its own memories of you. Turn sharing on and the facts you told one — memory cards and logbook lines — can surface for another, marked as secondhand, so you never say a thing twice. Their opinions and their own read of you stay their own. Off is truly off; nothing is copied.
