I've installed ScriptCat on non English versions of various chromium based browsers (Chrome, Edge, Vivaldi and Brave).
I've tried in all browsers setting their language to various languages (German, Italian and Greek).
When the default language in the browsers is not English ScriptCat defaults to Chinese and even if you change ScriptCat's language to English it changes it but it doesn't save the change and it goes back to Chinese.
At least the setting to use English should be saved and not to go back to Chinese.
Please devs of ScriptCat have a look at it.
International users if their language is not available in ScriptCat would prefer to get at least English and not Chinese.
Because it is more likely they know English than Chinese.
