An inheritance plan your family can actually open

Leave your family a map they can follow — without you.

Build a private map of everything that matters — bank accounts, Bitcoin wallets, documents, devices, people, and where access details are kept. 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.

How it works

Map it. Check it. Hand it over.

Step 1

Build the map

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

Leave them one file

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

Why this exists

Everything in your hands. Nothing in ours.

Built for my own family. Free, open source, and yours to verify — so it outlives even us.

Private by design

No servers, no tracking, no account. Your family's map never sits on someone else's computer.

Locked like a vault

Your plan file is sealed with the same encryption banks rely on. Without the passphrase it reveals nothing — to anyone.

Verify, don't trust

Free and open source. Every claim on this page can be checked in the code — by you, or anyone you trust.

Built to last

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