Private family photos
A family Chest is unlisted. People open it with an invite, not by finding it on a public feed.
A public feed is a poor place for family photos. A Chest stays unlisted. The owner creates it and invites the people who should see it.
A personal link expires 24 hours after it is created and works once. A personal QR code expires three minutes after it is created and works once. Each one adds one person. A wedding needs a different invite.
The guest joins with a display name. There is no email address and no password. OurChest does not add a location field to the photo.
