Beirut. Translator and localisation consultant. Lingo Desk reviews small-app copy. The bug classes that cost real trust:
Shame bugs (wrong gender/plural in user-facing strings; users read disrespect, not typos). Money bugs (currency formats, decimal separators, RTL amounts; money wrong is trust gone). Date bugs (calendar differences, first-day-of-week, formats; missed prayers, missed meetings, missed trust). Machine-smell (fluent but foreign phrasing everywhere; users smell MT and downgrade everything, even the correct parts).
Fix order: money first (trust), shame second (respect), dates third (utility), smell last (polish). One native review per release. Cheapest trust insurance available.
