Translator for Billingo

Translator for Billingo overlays an English or French translation on the Hungarian-only Billingo invoicing interface (app.billingo.hu), so you can read what you are clicking. HOW TO USE 1. Open app.billingo.hu and log in as usual. 2. Click the Translator for Billingo icon in your toolbar. 3. Choose English or Français. The page is translated instantly, in place. Pick "Magyar (off)" at any time to restore the original Hungarian. WHAT IT DOES • Live, in-place translation of the whole app: menus, tables, forms, dialogs, the invoice editor, settings, bank sync, inventory, KATA and flat-rate tax assistants. • Hand-curated dictionary of 8,600+ Hungarian strings, with deliberate choices for Hungarian fiscal and legal terms (VAT, reverse charge, corrective invoice, proforma, flat-rate tax, NAV codes) and a documented glossary. • Coverage measured on the real app, not claimed: 99.7 % of the strings rendered across 25 authenticated screens, and 99.96 % of Billingo's own string catalogue. • Beyond exact matches: indentation, trailing punctuation, casing, "3 db"-style counts and composed table headers are handled by eight lookup layers. • Fiscal safety: amounts, tax numbers, invoice serials, IBANs, dates and addresses are never rewritten. Your own data (partner names, product names, line items) is left untouched too; only the interface is translated. • Instant language switching, no reload. The original Hungarian is remembered per element, so switching back restores the page exactly. • Fast: the dictionary is sharded per app section and loaded lazily. • Miss export: the popup lists the strings it could not translate and lets you copy or download them, which is how the dictionary keeps growing. PRIVACY No personal data is collected and no network request is ever made. The dictionary ships inside the extension; your language preference is stored in your browser's sync storage. Nothing is sent to the developer or to any third party. The extension runs only on app.billingo.hu. REQUIREMENTS Chrome / Edge (Manifest V3) or Firefox 127+.
