Nothing shared by mistake.

Dead Man's Switch

If you stop checking in, Henedo waits, warns trusted contacts, then delivers sealed access exactly when you planned.

Sealed until unlocked.

Imagine to have avideo with yourgreat-great-grandmother.

Nobody saved that moment.

Your future generationwon't have to imagine.

You're the first in your bloodlineto leave a digital legacy.

For most of human history, people left behind only the smallest traces of themselves: a name carved into stone, a brief mention in a church record, a quiet proof that they were once here. The ability to preserve a voice, a laugh, a personality, or even an ordinary afternoon is incredibly new. For the first time in ten thousand years, someone in your bloodline can leave behind more than fragments. You are the first generation that future descendants may be able to truly know, not just remember existed.

Legacy isn’t just the house, the money, or the inheritance. It’s whether your great-grandchildren will still know who you were.

History lives only if preserved

We didn't build an app.We built the only wayto live forever.

Active preservation

Geo-redundant.Refreshed every decade.

Your primary storage is geo-redundant across multiple regions, and the underlying drives are migrated to current technology every ~10 years — the same active-preservation discipline national archives use. M-DISC (ISO/IEC 10995:2011/ECMA-379, rated up to 1,000 years) is an extra redundancy layer on top, not the primary medium.

Institutional permanence

Designed to outlast us.

We've structured Henedo so your data's future never depends on our continued existence, using legal trusts, accredited custodians, and a self-sustaining endowment.

01
Legal TrustA formally constituted irrevocable trust governs all assets and access, independent of any team, board, or parent company.
02
University PartnersFormal agreements with accredited universities and national archives guarantee custodial access long after commercial operations end.
03
Endowment FundA diversified, inflation hedged investment fund finances operations perpetually, remaining currency agnostic and autonomously managed.
04
Succession ProtocolA legally enforced and independently audited chain of custody. Documented, tested, and designed so no single person can sever your access.

Security architecture

Quantum-proof fromthe ground up.

01

Zero-Knowledge
Architecture

All data is encrypted client-side before transmission. Our servers function as blind relays, storing only ciphertext. Plaintext never exists outside your device.

02

Client-Side Key
Management

Encryption keys are derived and held exclusively in your browser. They are never transmitted, never stored remotely. A server breach yields nothing decryptable.

03

Post-Quantum
Cryptography

AES-256-GCM with 128-bit post-quantum security. ML-DSA-65 (NIST FIPS 204) for digital signatures. No legacy algorithms. No retrofitting.

The cost of doing nothing

What changes the day you sign up.

They tear through every drawer hoping a will exists somewhere. It doesn't.

The day you're gone, your signed will is already in their hands. Sealed. Final.

The recovery phrase lives only in your head. It dies the day you do.

Half on a metal card, half by email — both needed to unlock what you saved.

Twenty years of photos vanish the month no one renews the cloud bill.

Every photo and video, encrypted and copied across continents. Built to last centuries.

Your voice, your laugh, your stories — gone within one generation.

A video for her wedding. A letter for his 18th. Delivered the morning they need it.

Family fights in court for years over what you "would have wanted."

You name each person and exactly what's theirs. No fight, no judge, no probate.

Questions

Everything you want to know.

The Living Vault is your active, always-updated record: will, documents, passwords, contacts. It evolves with your life and is designed to deliver everything to the right people, then permanently delete itself. The Eternal Vault is a sealed time capsule, a permanent, cryptographically signed snapshot preserved for up to 1,000 years. One manages your legacy while you're alive. The other preserves it for generations. Living Vault is included in your subscription. Eternal Vault is a one-time purchase from $499.

The Journal is time-forward. Dated, free-form voice notes, video messages, and text entries. A daily chronicle of life as it happens, scheduled to deliver to the people you love on the days you choose ("her 18th birthday," "their wedding"). The Life Story is the inverse, time-backward. A curated bank of 1,000 prompts across ten dimensions of a life (childhood, family, love, career, lessons, funny moments, big decisions, legacy, beliefs, adventures), designed to surface memories you would not think to write down on your own. Same vault, same trusted contacts, same encryption. Most people use the Life Story for everything before now and the Journal for everything from now on.

Your data never depends on us. Every Eternal Vault is governed by an irrevocable legal trust with accredited university partners and custodians. A self-sustaining endowment fund finances operations independently. Even if the company ceases to exist, the trust structure keeps your vault intact. And if you ordered an M-Disc, you hold a physical copy rated for up to 1,000 years (ISO/IEC 10995:2011/ECMA-379, U.S. Department of Defense projection).

No. Everything is encrypted on your device before it ever leaves. Our servers store only ciphertext, encrypted data that is unreadable without your key. We use AES-256-GCM with zero-knowledge architecture. No one at Henedo can access or read your data. Not engineers, not support, not executives. A server breach yields nothing decryptable.

No. You choose how long the switch waits before activating: 1 month, 3 months, 6 months, 1 year, or longer. After that period of inactivity, all your contacts are notified and a grace period begins. During this window, a single check-in from you stops everything. You'd have to be completely unreachable for your entire chosen interval plus the grace period before any access is released.

Yes. Paid plans include a full will builder with jurisdiction-specific legal templates that meet signing and witness requirements worldwide. The free Witness tier includes only a watermarked template for preview purposes and is not legally binding. For additional assurance, attorney document review is available as an add-on ($79/document), with Legacy subscribers receiving one free review per year.

By design. The Living Vault is a delivery mechanism, not a monument. Once your contacts have received their designated access (passwords, documents, final messages), the vault permanently and irreversibly deletes after 60 days. This protects your privacy even after death. No lingering data, no future exposure. It does its job and disappears.

Each card is personalized with the contact's engraved name, a unique QR code, and an NFC chip. Cards are mailed within 14 days of signup. While you're alive, the cards exist but access is blocked. When the continuity switch fires, contacts receive a certified letter and can tap or scan their card to reach their designated portion of the vault. Think of it as a permanent physical key to a digital lock.

No. Once sealed, the Eternal Vault is cryptographically signed and permanent. That's the whole point. It's a verified record of a moment in your life. You can create multiple Eternal Vaults for different milestones: one at marriage, one at retirement, one per child. Each is a separate sealed chapter. Your Living Vault handles everything that changes.

It works like a university endowment. A portion of your one-time payment goes into a long-term capital reserve that funds storage and maintenance over time. As storage technology gets cheaper every year, the reserve grows while costs shrink. This model has sustained institutions for centuries, and it's how we guarantee your vault outlasts any subscription.

No. Contacts know they've been designated and they receive their access card or key, but the platform blocks all access while you're alive and checking in. They cannot see, browse, or preview any contents. Access is only granted after the continuity switch fires and the grace period expires. Until then, the vault is fully private.
