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.

FAQ
常见问题
密码和私钥会被平台看到吗？
保险箱内容会加密保存，后台默认不展示密码、私钥和助记词明文；法律 PDF 也不会导出敏感明文。
心跳检测会不会误触发？
心跳检测采用多阶段流程：先提醒本人，再通知可信联系人，最后才按用户设置释放资产或投递信件。
