What happens to your digital life when you're gone?

160+ online accounts per person. Only 24% have a digital estate plan. Your final messages, passwords, and crypto shouldn't die with you.

Without a plan

Family can't access important documents
Your crypto wallet becomes inaccessible forever
Password manager master key dies with you
Final messages never reach loved ones
Existing "encrypted" services can still read your data

With WillMessage

True zero-knowledge encryption for your sensitive data
Set automatic release when you can't check in
Choose who receives access and how
Bitcoin-verified, tamper-proof timestamp
Your encryption key never touches our servers

How It Works

Three simple steps. Complete zero-knowledge security.

Create

Build your vault with our browser tools, or bring your own encrypted file. Add messages, passwords, documents. Everything stays on your device until encrypted.

Encrypt & Anchor

Everything encrypts in your browser with a key only you control. Hash anchored on Bitcoin. Immutable proof the content hasn't been modified.

Deliver

Set your check-in schedule. If you can't respond, we notify your beneficiary via email, SMS, and postal letter with the encrypted vault. Only they can decrypt it, not us.

Three Ways to Deliver the Key

All zero-knowledge. Choose the level of security that fits your needs.

Default

Passphrase

You choose a passphrase that derives your encryption key. When the time comes, your beneficiary enters the passphrase to decrypt.

Create a strong passphrase and deliver it yourself

Key derived from passphrase
Beneficiary needs: The passphrase
Downloadable Recovery Kit

Best for: Anyone, corporate succession

Alternative

Shared Memory

Security questions that only you and your beneficiary can answer. Your answers derive the encryption key. We only see the questions.

"What year did we first meet?" "What was our first pet's name?"

Key derived from shared knowledge
Beneficiary needs: Nothing beforehand
Downloadable Recovery Kit

Best for: Family, partners, close friends

Pro Plan

Smart Contract

Key encrypted on blockchain. When the switch activates, an oracle delivers it to your beneficiary automatically.

Two systems. Neither has complete access.

Encrypted key stored on blockchain
Released via Chainlink oracle
Total separation of knowledge

Best for: Crypto holders, security professionals

Zero-Knowledge Means We Mathematically Cannot Read Your Data

Your encryption key never touches our servers. Even if we're hacked, attackers get useless encrypted blobs. This isn't "trust us" encryption. This is verifiable, auditable, cryptographic certainty.

Frequently Asked Questions

Everything you need to know about WillMessage.

No. Your encryption key never touches our servers — whether derived from shared answers, a passphrase, or stored in a blockchain contract. We store encrypted blobs that are useless without the key.

You can optionally generate a Recovery Kit when creating your vault. It's generated in your browser — we never see it. Store it securely: give it to a lawyer, put it in a safe, or deliver it yourself.

They still can't access your data. The Recovery Kit contains no logo, no URL, no identifying information about WillMessage. Even if they figure out it's ours and contact us, we never execute the switch manually. We only send the vault to the configured beneficiary email, only when the switch activates based on missed check-ins.

Your encrypted data is exportable. The encryption is standard AES-256-GCM — any implementation can decrypt with the right key.

Our crypto library is open source. The encryption happens in your browser using Web Crypto API. You can verify the code yourself.

Bitcoin for timestamping (via OpenTimestamps). Polygon for Smart Contract mode (low fees, EVM-compatible).

WillMessage is a secure storage and notification service, not a legal will. Consult a lawyer for legally binding estate planning.
