A private page for every person you care about.
Relational is a notebook for the people in your life. You write a note in your own words. Your iPhone reads it, shows you what it understood, and you say yes or fix it. Over time a page builds up for everyone you have written about.
It is being built for iPhone. It has not been released yet, and there is nothing to sign up for on this page.
The promise
We never see your notes — there is no server, no analytics and no account; the only things that ever leave your phone are ones you switch on yourself.
What that means in full, including the parts that are less flattering, is on the privacy page. It is written to be checkable rather than reassuring.
