Released if you stop checking in
People often describe this idea before they know its name: a way to leave letters for their family that would only go out if they stopped checking in. A safer version: letters released if you stop checking in and multi-step verification completes.
The popular name for this is a dead man's switch: something that happens if you stop responding. It's a useful metaphor. But the movie version (a timer runs out and everything is sent instantly) is the wrong design for something as precious as a goodbye letter. This post explains a safer version.
Myth 1: one missed signal sends everything
The myth: You miss a check-in and your letters go out.
A safer design: A missed check-in starts a careful process, not a release. In MemoryShield, the email life-check asks you on a schedule you set to confirm you're OK. While you answer, nothing is released and your trustees see nothing.
Here is what happens if you stop answering your email check-ins. Nothing is released because of one missed email. First there's extended monitoring: more check-ins, more time. Then your backup contact is notified; they can't see your vault. Then there's a waiting period. Only after all of that do your verified trustees receive the items you designated for them. MemoryShield doesn't certify death and has no death-certificate, legal or medical review step. Full walkthrough: How an email life-check and verification work before vault release.
The point is to avoid two failures: a letter that never reaches anyone, and a letter released because you were on holiday, in hospital, or your check-in landed in spam.
Myth 2: it's the same as scheduling a message
The myth: A switch is like scheduling an email for a future date.
The difference: MemoryShield has no scheduled or on-date delivery. Release depends on your silence plus verification, not on a calendar. If you'd like a letter to be read on a particular occasion, you can say so in the letter, and your trustee can choose when to hand it over.
Myth 3: a switch replaces planning
The myth: Set a timer once and you're done.
Reality: A switch is only as good as what it holds and who receives it. A workable plan has four parts:
- What you leave: letters, videos you record in your browser or upload, photos and documents
- Who receives it: named trustees who accept the role (naming doesn't unlock anything)
- The signal: an email life-check you can keep up with
- Verification before release: extended monitoring, a backup contact notice, a waiting period
Myth 4: text messages are more serious than email
The myth: A proper switch must use text messages.
Reality: MemoryShield's life-check is email only, by design. Choose an inbox you read and a schedule you can keep.
Myth 5: a will or a sealed envelope is the switch
The myth: A will or an envelope with a friend will "activate" when needed.
Reality: A will is a legal document; it doesn't run check-ins or hold your letters for specific people. See A will does not release your digital vault. An envelope depends on one person and can be lost or opened early. Neither is wrong; they solve different problems.
Side by side
| Movie-style switch | Email life-check with verification | |
|---|---|---|
| What starts it | One missed signal | Missed email check-ins |
| What happens next | Immediate release | Extended monitoring, backup contact notice, waiting period |
| Who receives it | Whoever is set up, all at once | Named, verified trustees, item by item |
| Early release risk | High | Designed to be low |
| Certifies death | Often implied | No. MemoryShield doesn't certify death |
A quiet note on security: your vault is encrypted at rest (AES-256), with escrowed keys so release can work after verification; not zero-knowledge. Item-level encryption is opt-in: you can turn it on for an item, and it's off unless you do. MemoryShield isn't a password manager or a will, and it can't open anyone's other accounts. How security works.
Questions to ask any "switch"
- What exactly starts the release?
- What checks happen before anything is sent?
- Who receives what, and can that differ by item?
- Can anyone see my letters before release?
- Does it claim to certify death or replace a will? (It shouldn't.)
