Lullia’s principles
Nothing is rewritten
Messages, notes and records can’t be edited or deleted.
No “online” or “last seen”
Nobody watches whether you’ve opened the app.
Both homes, same weight
Two colours of equal strength. People are shown by name.
Server time on everything
Every record carries the time it happened.
Lullia in 30 seconds
A week in two homes, without the back-and-forth.
The calendar, an exchange, a calm reply and a record export, as both parents see them. No sound needed.
A silent film, about 30 seconds long. Maya and Daniel share one calendar for Leo and Ava: two weeks fill in day by day, a full week in each home, with the exchange on Friday at 6:00 pm. At the exchange, Maya taps I’m here, Daniel checks in on his phone, Maya swipes to hand over and Daniel confirms. Both phones then show the same closed record with server times. Next, Maya’s sharp draft becomes a calm reply after she taps Calmer, and the sent message stays as written. An export lists record IDs, UTC and local times and a SHA-256 hash, shared read-only with an attorney. The film ends with: Free for the other parent, always.
How it works
Start from what you already agreed.
Upload your custody order and check each rule against the page it came from, or start from a common pattern. Holidays, school breaks and summer come in the same way, and nothing applies until you confirm it.

Alternating weeks
A full week in each home, one exchange a week.
Overnights over two weeks. Templates are a starting point, so always check them against your custody order.

Features
Everything two homes share, in one calm place.
Example thread. The other parent writes: “Can Leo bring his cleats on Friday? He has a game Saturday.” A sharp first draft becomes “Yes, I’ll pack them in his bag.” after the Calmer suggestion, and it is sent with no read receipts.
Messages that stay as written
Threads by subject, no read receipts, nothing edited after it’s sent. Optional tone suggestions only you see, and translation when you write in different languages.
Child support from Daniel to Maya: $1,150 a month, paid via the State Disbursement Unit. Eight of twelve months paid, one pending.
Money, kept straight
Child support, shared costs split 50/50, by percentage or by income, with receipts and deadlines. Pay with Zelle, Venmo, PayPal or Cash App. Lullia records the payment and never moves money.
Sample export page: exchange records, record X-2026-0141, 23:02 UTC · 6:02 pm local, with a SHA-256 hash.
Records for your attorney
Exports carry record IDs, UTC and local time and a SHA-256 hash. Give a mediator or attorney read-only access for set dates, and both parents see the access log.
Safety without fuss
Hide your address everywhere, hand over in public places, cover the screen in one tap and lock the app. Help is one tap away: 911 and the National Domestic Violence Hotline.
Travel consent for Toronto, Dec 20 – 27: signed. Change request to swap the weekend of the 18th: reply by Thursday.
Requests with a deadline
Swaps, reimbursements, travel consent letters and time offered first all land in one inbox. Nothing changes until the other parent answers.
Pricing
One subscription for the whole family.
The other parent never pays and never sees a paywall. Neither do mediators or attorneys you invite.
