Keepr is a private home for your family's photos and videos. This section covers what it is, how the pieces fit together, and — more usefully — what to actually do in your first ten minutes.
If you only read one page here, read Start with your household. Most people who don't get anywhere with a family photo app get stuck at the same place: they set everything up alone and then try to convince relatives to join something that already looks finished. Starting with the two or three people closest to you avoids that completely, and it's free.
Once you're set up, Privacy and sharing is the section worth reading next — it's the one that answers "who can actually see this?", which is the question the rest of Keepr is built around.
