When you're done, you can share in a boatload of ways, though I discovered that some are hidden until you enable them, like Gmail. And its designed to handle only one identity in order to add another you have to create a whole set of custom fields, and there's no way to organize them.
However, without a subscription it won't sync that info across devices. You enter all your personal information, as well as any other information you want to create a field for, and while filling in you can just tap it and have it fill.
There's a sort-of autofill option as well.
