Free forever

Co-parenting communication that holds up in court.

Kinbria keeps a secure, permanent record of every message, calendar change, and exchange between co-parents — and it can't be secretly changed. That's the one thing family courts rely on. Free for everyone.

Talking to a difficult co-parent shouldn't cost $300 a year.

Separated parents are told to keep everything in writing, in case it's ever needed in court. The apps that do this well charge per parent — often $110–$300 a year each — and the two biggest just removed their free plans. Kinbria does the same job, better on the part that matters, and it's free.

How it works

Documented in four simple steps

1

Create your account

Free in under a minute. You can begin even if your co-parent hasn't joined.

2

Message & schedule

Talk and coordinate custody in one place. Every message and calendar change is dated and permanent.

3

Generate a record

One tap turns your history into a sealed, dated official copy you can take to court.

4

Anyone can check it

A judge or attorney confirms it's genuine and unchanged on a public page — no account, no cost.

Everything you need

Built for the whole co-parenting job

Not just messaging — the complete toolkit, free.

Documented messaging

Uneditable, undeletable messages with sent and read timestamps. Both parents always see the identical record.

Shared custody calendar

Color-coded pickups, drop-offs and holidays. Every change is logged as court-grade evidence.

Certified records

Free, unlimited sealed and dated official copies for court — a "certified record" is one anyone can check.

Anyone can check them

Anyone can confirm a record is unchanged on a public page — without trusting us or seeing what it says.

Private & encrypted

Conversations are encrypted while stored and visible only to you, your co-parent, and people you invite.

Free for everyone

No per-parent fees, and you never pay to read, export, or share your own records. Hardship and domestic-violence access is automatic.

The difference

Records a court can trust — and anyone can check.

Each message is sealed to the one before it, so nothing can be secretly changed or reordered. When you generate a record, Kinbria adds a digital seal and a trusted date stamp. A short code lets a judge, attorney, or the other parent go to a public page and confirm it hasn't been changed — they can prove it for themselves, instead of taking our word for it.

Safety first

Designed with survivors in mind

Kinbria assumes the other parent may be difficult — or dangerous. Two-factor sign-in is required for protected accounts, invites never reveal whether someone has an account, there are no live "read receipts" that expose your routine, and you can sever an abuser's access while your records stay safely preserved. And because it's free, no one is ever priced out of documenting.

Questions

Common questions

Is Kinbria really free?
Yes — completely, with no per-parent fees, and you never pay to read, export, or share your own records. We keep it free by not building the expensive features that force other apps to charge (in-app calling, money transfer, huge file storage). Optional donations help cover hosting.
Are the records actually admissible in court?
Kinbria records are built to prove on their own that they're genuine, so you shouldn't need a witness just to confirm the file is real. Each one carries a digital seal, a trusted date stamp, and a signed statement from the person who keeps the records. Whether any specific record is accepted is always the judge's decision — Kinbria gives you the strongest possible foundation, but it isn't legal advice.
Can my co-parent edit or delete messages?
No. Once sent, a message can never be changed or removed, and both parents see the exact same history. That's the whole point.
What if my co-parent refuses to join?
You can begin on your own and keep your own record. Your entries are still saved and dated.
Who can see my messages?
Only you, your co-parent, and people you specifically invite (like a therapist or attorney) as view-only. Messages are encrypted while stored.
