Write a message to the future
One text message without attachments per day is free.
How a message travels through time
From writing to delivery, the message stays sealed. Nobody reads or changes it in between.
You write
Text, video or photos. You can send without registering.
We seal it
The message and attachments are encrypted in your browser before they leave your device.
We keep it
The message waits, encrypted, until the moment you chose.
We deliver it
The recipient gets an email (and optionally a paid text message) with a link. If you chose a password, they open the message with it; otherwise the link is enough.
Security we can describe precisely
No vague promises. We say what we encrypt, how we do it, and who can access the message.
Security detailsMessages and attachments, end-to-end encrypted
We encrypt the text, subject, file names and files in your browser with AES-256-GCM. When you choose a password, the key is protected by a password only you and the recipient know, and not even we can read the content.
Password or link only: your choice
With a password, the recipient unlocks the message in their browser and the password never reaches us, so we cannot recover it. Without a password, anyone with the link can open the capsule; we keep the secret from the link encrypted so we can send the link on the delivery day.
Unique link with limited validity
Every message has its own link. It works only for the period you choose.
Anonymous sending
If you prefer, the recipient won't learn who sent the message.
Your data, under your control
Delete your account and every stored message in one step from settings.
