Can I use Apiway in my own language?

Yes. The app interface is available in 11 languages: English (US), English (UK), Russian, Spanish, French, German, Portuguese (Portugal), Portuguese (Brazil), Arabic, Simplified Chinese, and Japanese. By default the app follows your browser language; to pick one explicitly, open Account → Interface → Language, or ask the chat (for example, “switch the interface to German”). Your choice is saved to your account and applies on every device.
