Letters that only go out if you stop answering
Write to the people who matter, in your own words, while you still can. We keep your letters sealed and check in with you now and then. As long as you answer, nothing is ever sent.

Made so nothing goes out by mistake
- Nothing is sent while you answer
- One sign from you stops the steps
- Every step is checked before anything is sent
How it works
Four steps. While you answer, nothing is ever sent.
- 1Write and sealLetters, photos and videos for the people you choose. Encrypted, and private until they are sent.
- 2We check inOn a rhythm you choose, from a few days to five years. One press on I'm here, and your letters stay sealed.
- 3If you go quiet, we look for youReminders by email and text message, phone calls, and, if you added them, the people you trust. Any sign from you stops these steps, and your plan carries on as before.
- 4A final check, then they go outEvery step must really have happened. Only then does each letter reach its person, once. Until that moment your letters stay sealed and encrypted.

What people use it for
Some letters only matter if something happens. These are a few of the reasons people write them.
- A trip or an adventureMountains, the sea, a long journey alone. Set it for as long as you are away.
- An illness or an operationWords for the people you love, written in peace while you can.
- Parents of young childrenA letter in your own words, for the day they need to hear from you.
- Things never saidThank you, I'm sorry, I love you. The words that are hard to say face to face.
- Work with riskFor pilots, sailors, soldiers, rescue workers and everyone who knows the risk.
- Practical thingsWhere the important papers are, who to call, what you would want. Never passwords.

Read about passes and pricesQuestions people ask
Is this a dead man's switch?
In a way, but a careful one. A missed check-in does not send anything: it only starts the safety steps, with reminders by email and text message, phone calls, the people you trust if you added any, and final warnings. Your letters go out only after every step has passed without a sign from you.
What does it cost?
Setting up and writing is free. To start, you choose a pass: $20 for 1 month, $40 for 3 months, $50 for 1 year, or $99 once, watched for 50 years. Passes can be paid once or renew automatically.
How do my people get their letters?
Each person gets their own private link by email or text message, and only once every step has passed. They open your words, photos and videos on a simple page, without an account.
Can I change or stop it?
Yes. You can change your letters, pause your check-ins or end your plan at any time. Ending keeps your letters for later, and nothing is sent.
Is this a will?
No. These letters have no legal force and cannot decide who inherits anything. For that, make a will with a lawyer.
Can a letter be sent by mistake?
Not without many chances to stop it: reminders, phone calls, the people you trust if you added any, and a final check that every step really happened. One sign from you stops these steps, and your plan carries on as before.
What if I am in hospital or without signal?
Pause your check-ins before you go: press “Pause check-ins” and choose up to 90 days. We will not ask you to check in until the pause ends. If you could not pause in time, nothing happens quickly: each step takes days, and a check-in, a sign-in or pressing 1 on a call stops these steps at once, and your plan carries on as before.
Who can read my letters?
Your letters are encrypted, and nobody reads them. Your people only get them once every step has passed.
