Dead man's switch: how it works for automatic message delivery
A dead man's switch is a safety mechanism that automatically triggers a predefined action — such as delivering messages — when a person stops confirming their presence over a set period. Originally used in the railway and nuclear industries, this device now applies to digital legacy planning, ensuring your important words reach your loved ones.
Origin and definition of the dead man's switch
The concept was born in the railway sector in the early 20th century: a conductor had to keep a pedal pressed to prove they were conscious and in control. If they released the pedal (loss of consciousness, illness), the train would stop automatically.
The principle boils down to three steps:
- A system regularly requests an activity confirmation (check-in)
- As long as the person responds, nothing happens
- If they stop responding for a defined period, the system triggers an automatic action
In the context of digital legacy, this action is the delivery of posthumous messages to designated recipients.
How Hugete's dead man's switch works
Hugete's mechanism, called HugVeille, is designed to be reliable without being intrusive. It operates in three phases:
Phase 1: the watch system (HugVeille)
You choose a confirmation frequency (30, 60, or 90 days). As each deadline approaches:
- D-7: first reminder by email and/or SMS
- D-3: second reminder
- D-1: final urgent reminder
At each reminder, a single click postpones the date. It's your way of confirming "I'm still here."
Phase 2: grace period and HugGuard
If you don't respond to any reminder, Hugete doesn't transmit immediately. A double safety net activates:
- A 48-hour grace period starts
- Your HugGuard (designated trusted contact) is alerted
- The HugGuard can confirm the transmission or block it
Phase 3: secure delivery
If the grace period expires without blocking, your Capsule's messages (Hugz) are delivered to each recipient (HugOne) via a personal HugBox — a secure page accessible for 12 or 24 months depending on your plan.
Dead man's switch vs digital will: comparison
| Criteria | Dead man's switch (Hugete) | Digital will | Handwritten letter |
|---|---|---|---|
| Trigger | Automatic (missed check-in) | Manual (after confirmed death) | Random discovery |
| Delivery time | 48h after expiration | Weeks to months | Unpredictable |
| Confidentiality | Encrypted, zero third-party access | Read by notary | Accessible to anyone |
| Cost | Free (basic plan) | €100-300 (notary) | Free |
| Supported formats | Text, photo, video, audio | Text only | Text only |
| Modifiable | Yes, anytime | Yes, at the notary | Yes |
| Delivery guarantee | Yes (HugVeille + HugGuard) | Depends on executor | None |
Security and confidentiality
- Message encryption: your Hugz are encrypted at rest — nobody, not even Hugete, can access them
- HugGuard without content access: your trusted contact is alerted but never sees your messages
- European hosting (GDPR): data stored on Hetzner servers in Germany
- Full reversibility: you can modify, delete, or deactivate your Capsule at any time
Frequently asked questions about the dead man's switch
What exactly is a dead man's switch?
A dead man's switch is a safety mechanism that automatically triggers an action (here, message delivery) when a person stops confirming their presence at regular intervals. The term originated in the railway industry.
What happens if I simply forget to respond to the reminder?
Hugete sends 3 progressive reminders (D-7, D-3, D-1) by email and SMS. If you don't respond to any, a 48-hour grace period starts and your HugGuard is alerted. They can block the transmission. A simple oversight isn't enough to trigger delivery.
Can my HugGuard read my messages?
No. The HugGuard is only notified that the watch period has expired. They can confirm or block transmission but never have access to your message content.
Can I disable the dead man's switch at any time?
Yes. You can disable HugVeille, change the reminder frequency, delete messages, or cancel your Capsule at any time from your Hugete dashboard.
Does the dead man's switch also work for fixed-date messages?
No. The dead man's switch (HugVeille) only applies to Capsule-type messages, delivered in case of prolonged absence. Fixed-date Hugz are sent automatically on the scheduled date without a watch mechanism.
How much does Hugete's dead man's switch cost?
The HugVeille feature is included in all plans, including the free plan. The free plan allows 2 Capsules. Hug Addict (€1.99/month) and Hug Eternal (€4.99/month) offer more Capsules and storage.
