The household

One household per browser, held under an anonymous HTTP-only cookie. There are no accounts and no password, which is why the share links carry their own warning.

Changing the base currency re-denominates balances, but the per-line rate captured when each line was written is kept — so an old foreign line does not silently re-price itself.

Where the outside numbers come from

Two keyless sources. Neither needs an account, and khata never presents a sealed sample as a live reading.

The method, in short

How money is attributed

For every line the payer's paid rises by the amount and each participant's share rises by their portion. Then net = paid − share, and a positive net means the household owes that person. An inflow follows the same rule, because receiving a refund on the household's behalf is arithmetically the same as fronting the money and recovering it. Each line keeps its own direction label so what the message actually said is never hidden.

Splitting uses the largest-remainder method, so the parts always sum to the whole exactly. Floor division would strand the remainder, and handing it to whoever came first in the list is the kind of small unfairness this product exists to remove.

Why the transfer count is minimal

Every transfer clears at least one outstanding balance and the last clears two, so from n non-zero balances no plan can use fewer than n − 1 transfers. The greedy pairing always pairs a debtor with a creditor, so it reaches that bound. khata reports the count and whether the bound held, so the claim can be checked rather than taken on trust.

What the trust score is

Six weighted factors summing to exactly one: evidence, confirmation, freshness, read confidence, rate discipline and dispute load. The Settle page shows each one's weight, the quantity it measured and the sentence explaining it, so the score can be audited. It is not a judgement about the people — only about how well the book is written down.

What is stored

• Ledger lines and their amounts, in a hosted Postgres.
• The original message text, because it is the evidence a line is checked against.
• Sealed audit events — no password, no card number, no document image.
• Nothing else. There is no analytics call, no third-party script and no font loaded from a CDN at runtime except the model weights you choose to download.
