How It Works
Seven steps across three phases — from setup to automatic release. Your secrets stay encrypted and unreadable at every stage.
Write Your Secrets
Write passwords, instructions, messages, or account details. Everything is encrypted on your device — we never see your secrets, and neither does anyone else.
Client-Side OnlyEncryption & Key Splitting
A unique master key is generated and your secrets are locked with military-grade encryption. The key is then split into two shares — neither works alone.
AES-256-GCM · SLIP-39Deliver the Recovery Key
Download a Recovery Kit PDF or copy the key. Share it with your trusted contact through a secure channel — they'll need it to unlock your vault if something happens to you.
Zero KnowledgeVault Goes Live
Your encrypted vault is stored on our servers — but it's unreadable, even to us. The failsafe timer starts counting. Status: Secured.
Encrypted at RestPeriodic Check-Ins
Check in on your own schedule — every 6 months, 1 year, or 2 years. You'll receive 7 escalating reminder emails before any deadline. One click resets the timer.
Failsafe TimerTrusted Contact Notified
If you stop responding, your trusted contact is emailed automatically. They combine both key halves, reconstructing the master key to decrypt your vault.
Key RecombinationPermanent Destruction
14 days after recovery, the vault and all encrypted data are permanently destroyed. No copies, no backups, no traces. The lifecycle is complete.
14-Day CountdownBuilt for Real Life
From crypto keys to final wishes — see how people use ArkVault to protect what matters most.
Crypto & Wallet Keys
Pass on seed phrases, exchange credentials, and hardware wallet PINs to someone you trust — without exposing them while you're alive.
Family Emergency File
Centralize bank accounts, insurance policies, and critical passwords so your family isn't locked out during a crisis.
Business Continuity
Solo founders and freelancers: ensure a partner or successor can access servers, domains, and client data if you're unreachable.
Final Messages
Leave personal letters, video links, or wishes for the people who matter — delivered only when the time comes.
Legal & Estate Documents
Store locations of wills, trusts, deeds, and safe-deposit-box keys alongside instructions for your executor.
Medical Directives
Share advance directives, medication lists, and physician contacts with your next of kin — automatically when needed.
Built-In Security, by Design
Every layer is an independent barrier. Even if one were compromised, the others keep your vault sealed.
Military-Grade Encryption
Your secrets are encrypted on-device with AES-256-GCM, the master key is mathematically split via SLIP-39, and everything is wrapped in quantum-resistant ML-KEM-768. No single person or system holds enough to unlock your vault.
AES-256-GCM · SLIP-39 · ML-KEM-768Hardened Access
Memory-hard key derivation (Argon2id), automated rate limiting, encrypted sessions, and strict transport security work together to block brute-force attacks, clickjacking, and cross-site exploits.
Argon2id · HSTS · CSPTransparent & Audited
Our cryptographic design is open to scrutiny, built for third-party audits and SOC 2 compliance, with a bug bounty program rewarding responsible disclosure by security researchers.
SOC 2Vault Lifecycle Protection
Every access attempt is logged with device and location data. After recovery, vault data enters an irreversible destruction countdown until permanently erased.
Audit TrailIsolated Infrastructure
Encrypted vault data, authentication credentials, and audit logs live on separate, geographically distributed servers with strict network isolation between them.
Geo-DistributedUndisclosed Measures
Several additional security mechanisms operate behind the scenes — intentionally kept confidential to prevent adversaries from studying or circumventing them.
Your Secrets. Yours Only.
ArkVault is built on a zero-knowledge architecture. We can't read your data — not because we choose not to, but because it's mathematically impossible.
We Never See Your Data
Your secrets are locked on your device before they ever reach us. By the time anything hits our servers, it's already encrypted into unreadable data. No one at ArkVault — not an engineer, not an admin, not anyone — can ever see what's inside your vault.
We Can't Unlock Your Vault
The key to your vault is split in two — one half stays encrypted on our servers, the other goes to your trusted contact. We can't unlock our half, and neither piece works alone. Even if our servers were breached, your data stays protected.
Beyond Legal Reach
If a government, regulator, or court order demands your data, we can only hand over encrypted blobs — which are useless without the keys we don't have. This isn't a policy. It's how the cryptography works. There is no backdoor, no master key, and no override. Your privacy is enforced by math, not promises.
