SpareKey Ledger

Spare keys go missing quietly. SpareKey Ledger keeps them accounted for.

Record every spare you have cut, who is holding it, and exactly which lock it fits — so the answer is never "somewhere in a drawer".

THE LEDGER
• Each key with a clear label and the lock it opens
• Who currently holds it — you, family, a neighbour, a tenant
• Where it is kept, for the ones that stay home
• Notes such as when it was cut or which door is the awkward one

CHECKED OUT
Filter to see every key currently with someone else. When someone moves out, you know precisely what should come back — and what needs re-cutting if it does not.

SENSIBLE PRIVACY
Fully offline. No account, no ads, no analytics, no internet permission. Label keys by nickname rather than address and the ledger stays useful without being a liability if you lose your phone.
