How Cubi came to be
Cubi is a private diary of a child, kept for the whole family — not a social network. This page sets out why Cubi exists, what it promises never to do, and what it is built on.
Why Cubi exists
A quiet space, not a feed
Cubi was made for days when the baby grows too fast, and for the people who love the little one from too far away. There are no likes to chase, no comments to answer — just one small heart sent to the baby. Cubi steps back quietly, so the family feels close and private, never watched. What is left is simply the baby, and the people who love them.
Far away, yet close enough to hold.
Four things Cubi will never do
No advertising
No ads between your child's moments, and your family's information is never used to target advertising.
No selling personal data
Cubi does not sell personal data. Technical data is shared only with the providers that run the service, and only as much as the service needs.
No public feed
Nothing is shown publicly. Only the people you invite can see anything, and every moment has a visibility scope you choose.
No likes to chase
No comment box, no counters, no pressure to reply. The family taps a single emoji, and that is enough.
What Cubi keeps, who processes it, and how it is deleted — all of it is in the Privacy Policy.
Who makes Cubi
Cubi is an independent product, made in Vietnam, for Vietnamese families.
Every choice here was the harder one. No ads means Cubi has to find another way to keep itself alive. No public feed means Cubi grows slowly, because there is nothing for strangers to pass around. No likes means there is no number pulling you back each day.
We chose them anyway. A child's diary should not be somewhere to sell advertising, and a baby's first days should not become content for strangers to scroll past.
There is no call centre here and no canned reply. Mail sent to hello@cubi.family goes straight to the people who make Cubi, and the person who writes back is a person.
