Create an encrypted vault that automatically delivers your keys, passwords, and instructions to the people you trust — only if you stop checking in. No one can access it early. Not even us.
How It Works
Three steps. Your secrets stay encrypted and unreadable at every stage.
Write Your Secrets
Add passwords, seed phrases, instructions, or messages. Everything is encrypted on your device with military-grade encryption — we never see your data.
Encrypted on DeviceSet Your Timer
Choose how often to check in — every 6 months, 1 year, or 2 years. Miss a check-in and a 7-day grace period begins with escalating reminders. One click resets the timer.
Failsafe TimerThey're Delivered When Needed
If you stop responding, your trusted contact is notified and can decrypt your vault with their Recovery Key. 14 days after recovery, the vault self-destructs. No copies, no traces.
Zero KnowledgeBuilt for Real Life
Your crypto keys are the most urgent use case — but ArkVault protects anything you can't afford to lose.
Crypto & Wallet Keys
If you hold Bitcoin, Ethereum, or any cryptocurrency, your seed phrases and private keys are the only way to access your funds. If something happens to you and no one has those keys, that crypto is gone forever — just like the $430 billion already lost. ArkVault encrypts your keys on your device and delivers them to your trusted contact only when needed.

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 encrypted on your device before they ever reach us. By the time anything hits our servers, it's already unreadable. No one at ArkVault — not an engineer, not an admin, not anyone — can 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. Neither piece works alone. Even if our servers were breached, your data stays protected.
Privacy by Architecture
If a government, regulator, or court order demands your data, we can only hand over encrypted blobs — useless without keys we don't have. There is no backdoor, no master key, and no override. Your privacy is enforced by math, not promises.
Simple Pricing
Your first vault is free. No subscriptions. No hidden fees.
