How check-ins and releases work

Lastkey uses a server-authoritative 3-strike engine to reduce false triggers while still providing a clear release path.

The 3-strike flow

1. Your check-in interval ends.
2. We send Signal 1 (gentle reminder).
3. If you still do not check in, we send Signal 2.
4. If you still do not check in, we send Signal 3.
5. Signal 3 is the final notice; if you still do not check in during the signal window, a release begins.

The time between signals is the signal window, set in your settings.

Checking in

Use Safety check-in in the dashboard anytime. A successful check-in:

• Resets the timer for all vaults.
• Clears any strikes.
• Cancels pending signals.

Adjusting the schedule

Go to Settings -> Check-in schedule to update:

• Interval (days)
• Signal window (hours)

Changing your schedule resets timers to keep things predictable.

What happens on release

If a release occurs:

• Beneficiaries are notified by email.
• Owners receive a confirmation email when releases are created.
• They can sign in to the release portal to decrypt locally.
• The "Read this first" note appears first to guide them.
