# Mia · Settings

Words are saved in your browser first (local-first). Sign in with Google to sync them to your Mia library — tutor, flashcards and dashboard all see them.

## Account

Checking…
Signing in enables cloud sync and AI definitions. Without it, Mia still saves words locally.

## Learning languages

English 中文 Español Français 日本語
Mia offers to save words and short phrases in the languages you pick. Spanish expressions may include punctuation such as ¿…? and ¡…!

## Backend

Mia backend URL
Default is the hosted app. Point it at `http://localhost:3002` for local development.

## Sync

New words sync automatically as you save them; this pushes everything already stored locally.
Fetches words that exist in the cloud but not in this browser (e.g. saved by Mia in chat). Never overwrites local words.
