One shared place for your child — across homes

Lina is one calm, secure line between two parents who share care.
Everything about your child — gathered in one place.

When plans, messages and photos are spread across different apps, important details get lost.
Lina brings structure and clarity to everyday cooperation.

A calmer way to cooperate

Lina is a shared space for co-parenting, focused on the child and designed to be calm, predictable, and supportive of cooperation between two parents — even in sensitive situations. Your data is private, secure, and shared only between the parents involved.

Without structure, small misunderstandings grow.

Lina gives you one shared space built specifically for parents who share care.

No social noise. No distractions. Just what matters.

Private by design

Lina is built with privacy as its foundation. Your data is protected through secure infrastructure, controlled access and signed links. Information is handled with respect and care. There is no advertising, no data sharing and no algorithm deciding what you should see — only a secure, structured space for cooperation.

Who Lina is for

Lina is made for parents who share care across homes and want fewer misunderstandings in everyday life. It is for those who value structure over noise and clarity over constant messaging. The structure supports cooperation regardless of conflict level, and helps create predictability even when communication feels difficult.

What Lina is not

Lina is not a social network, a general family chat or a place for endless conversation. It is a focused space designed specifically for cooperation around your child.
