Dead Man’s Switch is a scheduled check-in service for digital legacy and continuity. You choose how often to confirm you are still reachable: daily, weekly, or monthly. You add trusted contacts and attach the messages and files they would need if you stopped responding for good. Each contact can receive different content.

If you miss a check-in, the service does not release anything immediately. It sends reminders on the channels you enable: email, Signal, and Telegram. You configure grace periods and escalation so a busy week, travel, or a lost phone does not trigger delivery by accident. Only after that full sequence completes with no response from you does the system deliver what you stored. Messages and files are encrypted in storage and in transit; contacts see plaintext only after delivery.

Typical uses include passing on account recovery steps, locations of documents or hardware, instructions for a business or estate, and private notes meant for specific people. You can run test deliveries to verify addresses, wording, and attachments before the live switch matters.

Dead Man’s Switch is separate from Flare, which is built for coercion in the moment (silent alerts, decoys, delays, and a response plan under pressure). This product is for prolonged silence: wallets, passwords, legal material, and anything else that should not vanish because only you knew where it was. Subscriptions can be paused or cancelled when you want.

It complements legal planning and platform emergency-access features; it does not replace a will or formal estate documents. Where those tools define authority or inventory, Dead Man’s Switch automates handoff when check-ins stop and reminders and grace have run out, so people you chose receive what you left for them without depending on someone stumbling across a note years later.
