How it works

Three Steps

Write what's on your mind, let time deliver it

01

Write a Letter

Use Markdown or plain text to say what you want. Add images. End-to-end encrypted — only the recipient can read.

02

Set the Time

Pick a future date, or choose "on-death" delivery. Set up heartbeat monitoring so no letter is ever lost.

03

Relax

Letters are encrypted in storage. Scheduled letters auto-send on time. On-death letters trigger after heartbeat confirms inactivity.
