Who needs a Dead Man's Switch

📰

Journalists

Protecting sources

"If I'm arrested, this publishes automatically after 72 hours." A journalist investigating power structures sets up a Dead Man's Switch pointing to critical documentation. If they're silenced, the information releases to their editor, lawyer, or public repository automatically.

🗂ïļ

Whistleblowers

Evidence contingency

Whistleblowers facing retaliation need a guarantee that evidence will surface even if they're silenced. The Dead Man's Switch creates that guarantee without requiring trust in any individual.

🔑

Crypto holders

Digital estate planning

Billions in crypto have been lost because their owners died without transferring access. A Dead Man's Switch with a 30-day check-in delivers seed phrases and wallet access to heirs automatically — without leaving plaintext credentials anywhere.

ðŸĒ

Business owners

Knowledge transfer

Critical operational knowledge should not live in one person's head. A business owner sets up a Dead Man's Switch with key passwords, vendor contacts, and crisis procedures — releases to their COO if they're unreachable for 14 days.

How It Works

1

You write the secret

Your message is encrypted in your browser with AES-256-GCM. We only receive ciphertext. Set your check-in interval (daily, weekly, monthly).

2

You check in regularly

Visit your personal check-in URL before the deadline. This resets the countdown. As long as you check in, the secret stays sealed.

3

Miss a check-in

If you fail to check in by the deadline, the switch activates. The secret link is sent to your designated recipient or fires to your webhook URL.

4

Delivery is guaranteed

The trigger fires to your recipient's email or your webhook (Slack, Zapier, etc.) with the decryption link. They open it once — and it burns permanently.

Important: bookmark your check-in URL

After creating your switch, you receive a personal check-in URL. Bookmark it immediately. If you lose this URL, you cannot check in — and the switch will eventually trigger.

We recommend setting a recurring calendar reminder at 70% of your check-in interval (e.g., if the interval is 7 days, set a reminder every 5 days).
