🔐 The half no one else has · breach-proof by design

The combination, not the safe.
The PIN, not the phone.

Leave the people you love the half they'll need — a phone passcode, a safe combination, where the will is, a letter. Useless without the thing you keep at home, released only if something happens to you.

How it works

Set it up once. Then it just waits.

1
Add the half they'll need
A safe combination, a phone passcode, where the will is, a life-insurance policy, a letter. You store the code or the pointer — never the physical thing itself. Encrypted the moment you type.
2
Choose who receives it
Assign a trusted person to each record. They're invited and confirm once — but see nothing until the day comes. Family, a lawyer, a close friend.
3
We check in with you
Every so often we ask you to confirm you're OK. One tap and everything stays private. If your check-ins ever stop, your trustees receive exactly what you left them — never a moment before.
Why it's different

Not a password manager. Not a will. The half in between.

🔐
You hold the other half
We keep the code; your home keeps the thing. The phone, the wallet, the safe are never uploaded — so what we store is useless on its own.

🛡️
Breach-proof by design
Because the other half was never here, a breach reveals nothing usable. Security isn't a promise — it's the shape of the product.

The things that would be lost
A life-insurance policy no one knew about. An account abroad. Where the will and the solicitor are. Knowledge that otherwise vanishes.

Words, not just codes
A letter to your children. The story behind a ring. Funeral wishes. The irreplaceable things get equal billing — not an afterthought.

It points to your real will
Testamently isn't a legal will. It can hold a copy or simply name the solicitor who keeps the original — so your family knows exactly where to look.

📧
Released only if needed
A gentle check-in confirms you're OK. Nothing is shared while you're here — and you're told exactly what would happen, and when, if you ever stopped.

Built for long-term trust and reliability

Testamently only ever holds one half of the lock. The other half — the phone, the wallet, the safe — lives with you and is never uploaded. So what you store is safe even from us.

FAQ

Frequently asked questions

What is Testamently?+

Testamently is a private vault for "the half they'll need" — the codes, locations and messages your loved ones would need if something happened to you. A safe combination, a phone passcode, where the will is, a life-insurance policy no one knew about, a letter. You store the half that's useless on its own, and it's released to the people you choose only when it matters.

How is this different from a password manager?+

A password manager keeps live logins for you to use every day. Testamently is the opposite: you deliberately store only the harmless half — the PIN, not the phone; the combination, not the safe — so it's worthless to anyone who doesn't also have the physical thing you keep at home. It's built to be handed on, not used daily.

Is it a legal will?+

No. Testamently is not a will, trust or estate-administration service and is not a substitute for one. It complements your official will — it can hold a copy or simply point your family to the solicitor who keeps the original, so nothing important gets lost.

What if Testamently is hacked?+

It's breach-proof by design. We only ever hold one half of the lock; the other half — the phone, the wallet, the safe — lives with you and is never uploaded. Everything is also encrypted in your browser before it reaches us. A breach reveals nothing usable, because the half that makes it useful was never here.

How does the check-in (dead man's switch) work?+

You choose a check-in interval. As long as you check in, nothing happens and no one sees anything. If your check-ins stop past your grace period, your chosen trustees are notified and given exactly what you left them. A verified death certificate can also trigger release.

How do my trustees get access?+

Each trustee is invited and confirms once — but sees nothing until the day comes. They sign in from any device, years later, with just their own login. No hardware key, QR code, or browser file to lose. Designed to survive device changes and decade-long time horizons.

How much does Testamently cost?+

There is a free plan with 10 records and 5 trustees. Paid plans start at $29/year and add unlimited records, SMS alerts, more storage, and stronger protection for your most sensitive items.

Make sure nothing important is ever lost.

Free to start. No credit card required. Your first record takes two minutes.
