Corrections and changes

When a page or a calculator turns out to be wrong, the fix is listed here with the day it went up and what the site does now. Changes to the rules and new calculators are listed below it. The methodology page always shows the rules as they are today.

Corrections

October 31, 2026. The Mongolian tugrik rate for October 30 to November 15, 2025 was stored about 4,400 times too low, so a receipt in tugrik on those days came out far too large. Those days are now empty and use the last rate published before them, and a value that far from recent rates now waits until a person has checked it.
October 31, 2026. A share link could show a different amount the day after it was sent, once a newer rate was published. A new link now keeps the rate day it was made with. Links made before this change still recalculate when opened.
October 18, 2026. The page-not-found page loaded the Google ad script, although it has nothing to read. It no longer loads ads.
September 29, 2026. Pages that open a shared link loaded ads. An ad request includes the full page address, and there the address carries the settlement or its link id. Those pages no longer load ads, and the privacy policy says so.
September 27, 2026. On the restaurant bill, an even split showed an amount per person even when the number of people was empty, 0, a fraction or more than 50. It now shows no result until the number of people is valid.
September 27, 2026. The trip page said that nothing was sent anywhere. That was not true once you create a share link, which stores the settlement on our server. The page now says what happens, and a test keeps the old claim out.

Changes

October 18, 2026. The guest of honor and move-out pages name where their rules come from, and every calculator page says what happens to what you enter.
October 18, 2026. A new guide measures how much two years of exchange rates moved while a group waited to settle up.
October 12, 2026. The move-out calculator: final bills by days lived, the deposit and shared stuff. Each bill shows its daily rate.
October 11, 2026. The guest of honor calculator: treats are split by the people who shared each receipt.
September 30, 2026. A receipt can be edited in place on the trip calculator.
