What Is a Proof of Life Protocol?
A proof-of-life protocol is a process that requires a person to periodically confirm that they are still able to respond. In a digital system, that confirmation can be a recurring check-in. If the expected check-in does not happen, the system can begin a predefined escalation process.

What does "proof of life" mean in a digital system?
In this context, proof of life does not mean a legal certificate or medical determination. It means a recurring action that shows the account owner still has access and is responding. The system only knows whether the expected check-in happened.
How a digital proof-of-life check-in works
A schedule is created
The user decides how often the system should expect a check-in.
The check-in becomes due
The user is reminded that confirmation is required.
You check in
Enter your PIN to confirm the check-in.
The user does not confirm
The system treats the check-in as missed and begins the configured grace period.
The grace period provides another chance
The user can still check in and stop the pending escalation.
The grace period expires
The system follows the release rules configured in advance.
How AnyCircumstances uses check-ins
AnyCircumstances uses recurring check-ins as the trigger layer for its encrypted-file release system. The user chooses the schedule, configures email reminders, sets a grace period, and selects trusted recipients. If the user stops checking in and the grace period eventually expires, recipient delivery begins.
Proof of life vs dead man's switch
The check-in is the proof-of-response signal. The dead man's switch is the automation built around the absence of that signal. One asks, "Did the user respond?" The other answers, "What should happen if they do not?"
A missed check-in is not proof of death
A missed check-in can happen for many reasons. Someone may be traveling, sick, offline, locked out of an account, or simply late. AnyCircumstances does not determine why a check-in was missed. It only follows the schedule and grace-period rules the user configured.
Why a grace period matters
A grace period reduces the risk that a single missed deadline causes an unintended release. It gives the user additional time to respond while preserving the ability to act automatically if the lack of response continues.
Common uses for recurring check-ins
- emergency information for family
- encrypted document delivery
- cryptocurrency recovery instructions
- business continuity information
- private account instructions
- travel contingency planning
- instructions for dependents or pets
How often should you check in?
Choose a schedule you can realistically maintain. A very short schedule creates more opportunities for accidental misses. A very long schedule delays the point at which the system can respond. The right interval depends on how quickly your recipients would need the information and how reliably you can complete the check-in.
