Open When

You wonder who is
on the other side of this

Dear you,

We did not set out to build an app. We set out to fix one small, common heartbreak: you have something real to say, and nowhere good to put it. A text gets buried by lunch. A card arrives three days early. And the words that matter most — for a bad day, a long flight, the first morning in a new city — are exactly the ones that need to arrive later, not now.

So we made somewhere to keep them until then.

Since February 2026, 12,000+ letters have been sealed here by 6,000+ people. We have no idea what is inside a single one of them, and we never will — that was the whole point. But we know some were written at 2am. Some were written by people who could not say it out loud. Some are still sitting there, sealed, waiting for the day they were meant for.

Thank you for trusting us with those words. Honestly, it is the best part of doing this. Every time a rating comes in saying we helped someone say something hard, we read it out loud to each other.

If you have already written one here: thank you. If you have not yet, there is probably someone in your life who is overdue.

What we promise you in return

The letter itself stays free

Writing, sealing, and sending will never cost anything. The paid extras exist so the free part can keep existing — not the other way round.

We never read your letters

We can see how many letters are written and how many get opened. We never open one, and we never sell anything about you or the person you sent it to.

No account, no email, no trail

You came here to write, not to register. Nothing here asks who you are, and letters expire rather than pile up forever.

When you tell us something, we change it

Longer letters, free stickers, note jars, a free sticker of your own — each of those exists because somebody wrote in and asked for it.
