=== User: Here’s a screenshot of a text field on a banking app that i use. ===
Here’s a screenshot of a text field on a banking app that i use. It shows a context menu with Chinese characters option. My phone is only set to English and not Chinese and the option is only available on this app. What could cause this?

=== Assistant: This usually isn’t caused by your iPhone system language — instead, it comes from the app itself. ===
This usually isn’t caused by your iPhone system language — instead, it comes from the app itself.

Here are the most likely reasons why you’re seeing Chinese text options only inside this banking app:

===== ✅ 1. The app embeds its own custom text-processing menu =====

Some apps don’t use Apple’s default text-selection menu.
They inject their own UIMenuController items, including language-specific tools like:
* Simplified/Traditional Chinese conversion
* Character suggestions
* Translation shortcuts

If the developers reused a component originally made for a Chinese market, those options can appear even if your phone is set to English.

===== ✅ 2. The app uses a hybrid framework (React Native, Flutter, WebView) =====

When apps use embedded WebViews or hybrid UI components, some frameworks include built-in Chinese language tools.
This would show additional menu options that your system normally wouldn’t display.

===== ✅ 3. The app supports Chinese as a secondary language internally =====

If the banking app supports Chinese (even if you never switched to it), iOS can expose language-specific actions for text fields.
This can trigger the “简 ⇄ 繁” (Simplified ↔ Traditional) option.

===== ✅ 4. Part of the app thinks the input field is Chinese-compatible =====

Developers can specify text input traits like:
* UITextInputMode
* textContentType
* keyboardType

If they accidentally configured something like a Chinese input hint, iOS may suggest Chinese-related tools automatically.

===== Is this harmful or a security risk? =====

❌ No, it’s just a UI/UX quirk.
It doesn’t mean your phone is compromised or that the app is unsafe.

===== If you want to test: =====

You can check if it’s app-specific by opening the same clipboard menu in:
* Notes
* Safari
* Messages

If the Chinese options do NOT appear there, then the app is adding them.

If you want, I can look at the specific app (just tell me the name) and confirm whether it's known to use hybrid UI components that commonly cause this.
