Say it when it's time.
Write it whenever you're ready — a hard truth, a birthday wish, a prediction before the big reveal. Nobody reads a word, not even you, until the box opens, together, on the schedule you set. Not even the person who made the box gets to peek early.
No early peeks — not even for the person who made the box. Once a note's in, it's sealed for everyone until the box actually opens. There's no override, no admin key, no back door.
No ads, ever. We don’t sell or share your data. Kept isn’t funded by watching what you write — it runs on what people pay for it, full stop.
Kept isn't a chat. It's a place to put down the thing you're not ready to say out loud yet — and trust that it'll land at the right moment, for everyone at once.
Notes are unreadable to everyone — including whoever wrote them, and whoever created the box — until its next opening. No admin override, no peeking, no editing after the fact.
Invite anyone with a code — a partner, your kids, a therapist. They can watch the countdown and read what opens. They can never write or edit.
Daily, weekly, monthly, or just once — or the moment everyone agrees they're ready. A reminder lands before it opens, so nobody's caught off guard.
Write a note whenever it's on your mind. It disappears from view the second you save it — even from you.
Everyone with access watches the same countdown. A reminder nudges you before it's time.
At the moment you set, every waiting note reveals at once — to everyone, together.
What opened stays readable forever. The box locks again, ready for what's next.
Every box you're part of
Locked, with a live countdown
Everything opens together
Some of it's hard to say out loud. Some of it's just better as a surprise. Either way, it's worth everyone hearing it at the same moment.
Write to each other all year — the small stuff, the big stuff. It opens once, every year, on the day that means the most.
A standing Sunday box for appreciation, friction, what needs to change — without it turning into a fight over dinner.
Start it the day they're born. Grandparents and family add to it for years — nobody, including the parents, reads a word until the day they turn 18.
Everyone writes down where they think they'll be in ten years. Seal it at graduation. Read it together at the reunion.
Guests write something private at the reception. It stays sealed until the couple's first anniversary — a second wave of love, a year on.
Friends write down hopes, predictions, and a little trash talk on January 1st. Nobody looks again until next New Year's Eve.
Family adds a note whenever there's something worth remembering — a first step, a hard year, advice for later. It opens the day they walk at graduation.
Everyone locks in a prediction — the launch date, what'll break, who'll be right — before the work starts. It opens the day the project ships.
Kept is in early access on Android and iPhone, installed straight from the browser — no app store required.
