7 Features
One platform.Your legacy, protected.
Henedo is a single zero-knowledge platform with seven surfaces: a will builder, an encrypted vault, a 1,000-prompt Life Story, crypto inheritance, a dead man’s switch, a multimedia journal, and a 100-to-500-year Eternal Vault. Every feature shares the same trusted contacts, the same encrypted store, and the same release rules, so you set things up once, then keep updating instead of re-doing.
The seven featuresthat make up Henedo.
Each feature is a full product on its own. Together, they share the same encryption, the same contact list, and the same release controls, so adding one never means re-keying or re-uploading what you’ve already done.
Digital Will
Legally-recognized will, all 50 states.
Attorney-reviewed templates. Build in two minutes. Update unlimited times. Generate, sign, and store your will alongside everything an executor will need.
- State-specific witness and notary clauses
- Unlimited updates as life changes
- Auto-paired with the rest of your vault
Digital Vault
100 GB, end-to-end encrypted.
Insurance, deeds, tax records, password vault, recovery codes, all stored zero-knowledge under a key only you hold. The server never sees plaintext.
- AES-256-GCM with Argon2id-derived keys
- Device-bound Account Secret Key
- Open formats. Free export, anytime.
Crypto Inheritance
Don’t let your Bitcoin die with you.
40 million Americans own crypto. Most have no plan. Henedo stores recovery phrases with split-key delivery and only releases on a controlled trigger.
- Seed phrases for hardware and software wallets
- Engraved NFC card + email completion code
- Works with Ledger, Trezor, MetaMask, Phantom, and more
Dead Man’s Switch
Release on inactivity. Never before.
A 5-week warning cascade after 180 days of silence, gated server-side. Your trusted contacts already hold the keys. The switch only unlocks the ciphertext.
- Configurable inactivity window
- Email + SMS escalation cascade
- Server-side policy gate, even for compromised keys
Journal
The journal that becomes a legacy.
Daily text, voice notes, video, and photos. Encrypted under your master key. Scheduled to deliver to the people you choose, on the date you decide.
- Voice and video messages, not just text
- Per-recipient delivery rules
- Date-locked or trigger-based release
Life Story
1,000 questions. The person behind the documents.
A curated bank of 1,000 prompts across ten dimensions of a life: childhood, family, love, career, lessons, legacy. Voice, video, or text. The memoir layer no other estate-planning product ships.
- 10 categories × 100 prompts each
- Voice and video answers, encrypted under your master key
- Released on the dead man's switch or sealed for 500 years
Eternal Vault
100–500 years. Post-quantum signed.
A permanent, cryptographically-signed record of your life. Inheritable across generations. Ed25519 today, ML-DSA-65 against quantum tomorrow.
- One-time purchase, no subscription decay
- Hybrid classical + post-quantum signatures
- M-DISC physical backup option
Me + Partner
Single bill, shared storage, separate wills.
Either of you can leave anytime — your data stays with you. One person pays, the partner joins free. Each keeps their own private will, life-book, and journal under their own keys.
- Shared storage pool across both partners
- Separate private wills and journals per person
- Save $24/year on Guardian, up to $1,190 over 3 years on Couple Legacy 1 TB
How the features work together
Most legacy products are silos: one app for the will, another for the vault, a spreadsheet for the crypto, a sticky note for the passwords. When something needs to release, no single system has the full picture, and your family has to assemble the pieces under the worst conditions imaginable.
Henedo is the inverse: one product, seven internal subsystems, each isolated by design but sharing the primitives that matter. Three of those primitives are user-facing.
01 · Encrypted store
One vault, every feature.
Will documents, scanned deeds, recovery phrases, journal entries, and Eternal Vault manifests all live in the same AES-256-GCM store, keyed off your device-bound ASK.
02 · Trusted contacts
Add a person once.
Each contact you designate already holds their decryption material the day you add them: engraved NFC card on Legacy and Eternal, email completion code on Guardian. Will, vault, journal, and crypto all share that same contact graph.
03 · Release rules
One switch governs all.
The dead man’s switch is the single server-side gate. Until it fires, ciphertext is never served, even to a contact who holds a valid key. After it fires, every feature unlocks together.
Which features come with which plan
Witness is free and gets you started. Guardian and Legacy are monthly subscriptions that cover all five day-to-day features. Eternal Vault is a separate one-time purchase you can add to any tier. See full pricing.

Frequently asked
Get started
You don’t have to set everything up today.
Start with the will. Add the vault next week. Configure crypto inheritance the week after. Every feature stays in sync, and your trusted contacts only ever need to be added once.
