## FAQ

### What frameworks does localize.dev support?

It works with React, Next.js, React Native, Vue, Svelte, Astro, Angular, Flutter, iOS, Android, Rails, Django and Laravel.

### How is my data handled during translation?

The API only receives the UI text, file path, and short component context, never whole files, and uses models that do not train on your data.
