Lend a drill to a neighbour, give it a return date, and record the handback. This ledger keeps a date and a name. It does not keep money, and it has no clock of its own — a loan ends when a person says it ended, and not a moment before.

What this ledger does and does not do. It has no clock inside it. Nothing here decides that a loan has finished, ever; an overdue loan still reads as out, because an item in somebody else's house does not come back by being late. Only the Record the return button — pressed by the borrower, or by the steward who owns the item — writes a return, and it writes one exactly once. It cannot check who you are: whoever's name you type is the name the ledger keeps. And it cannot tell you whether the drill came back with all its bits. It records that somebody said it did.

You

Nothing else identifies you. This page has no accounts, no passwords and no verification — the name above is a label you chose. It is the same name the borrower must use to bring their own item back.

Put an item in the cupboard

Lend it out

A return date is read as midnight UTC on the day you pick, and it has to be a date this ledger can actually read — a half-typed one is refused rather than guessed at, because a guessed deadline tells a borrower a lie about when they are late.
