# UI languages are Portuguese, English and German

**Status:** accepted · **Date:** 2026-11-13 · **Implements:** RNF02

**Enforcement:** `[test]` the locale parity tests in `apps/mobile`, `apps/web`, `packages/errors`, `packages/email` · `pnpm i18n:check`.

The template shipped en, de and fr. BJJ Travel ships **pt** (Brazilian Portuguese, the base language of the prototype), **en** and **de** (German uses "du" with instructors and "Sie" in B2B academy contexts, as the prototype does). French was removed everywhere; device languages `pt-*` resolve to `pt`.
