How to change language on KuCoin? (Interface settings)

Accessing Language Settings

1. Log in to your KuCoin account via the web platform or mobile application.

2. Navigate to the top-right corner of the interface where the user profile icon is located.

3. Click on the profile icon to open the dropdown menu containing account-related options.

4. Select “Settings” from the dropdown list to enter the configuration panel.

5. In the left-hand navigation sidebar, locate and click on “Interface Settings”.

Selecting Preferred Language

1. Within the Interface Settings page, locate the “Language” section.

2. A dropdown menu displays all supported languages including English, Chinese (Simplified), Chinese (Traditional), Korean, Japanese, Spanish, French, German, Arabic, Russian, Vietnamese, Thai, Indonesian, Turkish, Portuguese, Italian, and Dutch.

3. Click the current language label to expand the list and scroll through available options.

4. Choose your desired language from the list — selection is applied instantly without requiring confirmation or reload.

5. The entire UI, including navigation menus, trading panels, order forms, and system notifications, updates immediately to reflect the new language.

Mobile App Language Configuration

1. Open the KuCoin mobile app and tap the “Me” tab at the bottom navigation bar.

2. Scroll down and select “Settings” to access global configuration options.

3. Tap “App Language” under the “General” section.

4. A modal window appears listing all available interface languages.

5. Tap the target language — the app automatically restarts its UI layer to render all text elements in the selected language.

Browser Cache and Persistent Display

1. After changing the language setting, some legacy browser cache may temporarily retain previous text strings.

2. Clearing browser cookies and cached files ensures full synchronization with the updated language preference.

3. On Chrome, Edge, or Firefox, navigate to settings > privacy and security > clear browsing data, then select “Cached images and files” and “Cookies and other site data”.

4. KuCoin does not store language preferences server-side per session; instead, it relies on local storage and HTTP headers for consistent rendering.

5. Repeated language switching across devices does not affect account security parameters or two-factor authentication status.

Frequently Asked Questions

Q1: Does changing the interface language affect API response formats? No. API endpoints return JSON payloads exclusively in English regardless of UI language selection. Field names, error codes, and documentation references remain unchanged.

Q2: Can I set different languages for trading interface and email notifications? Email notifications use the language associated with your registered region and cannot be decoupled from interface language settings. All official correspondence follows the same linguistic configuration.

Q3: Why does the futures margin calculator still display values in English after switching to Chinese? Numerical labels and unit identifiers such as “USDT”, “BTC”, or “%” are retained globally across all language modes to maintain consistency in financial interpretation and prevent misreading of contract terms.

Q4: Is Korean language support available for the KuCoin Web3 Wallet extension? Yes. The standalone KuCoin Web3 Wallet browser extension fully supports Korean localization, including wallet creation prompts, transaction signing interfaces, and token approval screens.
