An inheritance plan your family can actually open

Nothing breaks if you're gone tomorrow.

Build a private map of everything that matters — bank accounts, Bitcoin wallets, passwords, documents, people. Your family opens one file when the time comes.

The problem

You've planned for everything but this.

If you were gone tomorrow, could the people you love actually reach what you left them?

The map is in your head

You know where everything is — which accounts exist, which key opens what, whom to call. That map leaves with you.

Nobody calls your family

Banks, insurers and exchanges wait to be asked. An account nobody knows about is never claimed — it just sits there.

Locked means locked

Phones, accounts and wallets are built to keep strangers out. Without you, your family is just another stranger.

Step 1

Build the map

Every account, wallet, key and document — where it lives and who can reach it.

Test it together

A dry run with the person who'll use it — find what's confusing while you still can.

Step 3

Leave them one file

They double-click it — it opens offline, no app, no account.

Why this exists

Built for my own family — free and open-sourced, so it outlives even us.

Private by design

No servers, no tracking, no account. The plan never leaves your device.

Encrypted at rest

Locked with AES-256-GCM before it leaves your hands. Without the password, the file reveals nothing.

Built to last

Plain, open files in a documented format — readable in twenty years, with or without us.
