Longer pieces, for when the short answer is not the one you needed.

The three pages behind the tabs above cover what WillSignal does, how it protects your messages, and the specific questions people ask. These go wider — into the idea itself, the safeguards in detail, and the part nobody can automate: deciding what to say.

What a dead man’s switch is

Where the idea comes from, what it does when applied to messages, and the one thing it can never tell you. Also what separates a switch worth trusting from a countdown with a send button.

How WillSignal keeps a message from arriving early

Every safeguard against premature delivery, in order: before your signal runs, while it runs, when something breaks on our side, and what is left if all of that fails. Includes the two features deliberately not built, and why building them would make delivery less safe.

How to leave messages for the people you love

The practical one. Who to write to, what to write, how long it should be, and the mistakes that quietly undo the whole plan — including the one that stops delivery working at all.

More are being written. If you are looking for something specific, the FAQ is probably faster.
