## Switching language

Go to Settings → Preferences → Language and choose English or Spanish. The change applies immediately throughout the app. No restart required. Your home screen and lock screen widgets also update to match.

## What is translated

All app UI (labels, buttons, settings, messages, and alerts) is available in both English and Spanish. The Spanish translation uses U.S.-neutral Latin American Spanish with an informal (tuteo) register.

The following are **not** translated, as they are proper names or official designations:

- Stop names and street addresses
- Route numbers and route letters
- Transit agency names (e.g., Muni, BART, MTA)

## Storage

Your language preference is stored on your device only. It is never sent to any server.
