How it works
Three simple steps. No accounts, no servers.
1

Set your check-in interval

Choose how often you want to receive a check-in email — daily, weekly, monthly.

2

Set your inactivity period

Define how long without a check-in before the deadman switch activates.

3

Add your recipients

Add up to 20 email addresses. If the switch activates, they all receive your message.

Features
Simple by design
🔒

Your Data

Self-hosted and runs locally. Deploy on Start9 or any private server. Your data never touches a third-party.

Live countdowns

Real-time timers show exactly when your next check-in is due and when the switch would activate.

📧

Up to 20 recipients

Add as many trusted contacts as you need. Everyone gets notified with their own separate email.

🛡️

Open source

Fully auditable code. No black boxes. You know exactly what runs when the switch activates.

Pairs with Legacy

Encrypt your seedphrase with Legacy on your SeedSigner and scan it straight into your Deploy email.

🧪

Test immediately

Set your intervals to minutes and run the full sequence yourself before going live.
