A bug report is most useful with the exact sentence, the direction it was going (English → Thai, and so on), what the app showed and what it should have said. A screenshot covers most of that on its own.
Questions
The translation is wrong. What do I do with it?
Send it. Wrong translations and wrong word colours are the material the app is tuned on, and every reported sentence goes into the list that gets worked through. It is the single most useful thing you can send.
Does it work without a connection?
Yes, for languages you download: open the language list and tap Download next to Thai or Chinese (iPhone, iOS 26 or later). Those sentences then translate on the phone, even in airplane mode. Word meanings for a new sentence appear once you are back online, and history saves then too. Without a download, translation needs a connection.
Is what I type private?
Your dictation and your camera never leave the phone. Guest translations are not saved as history; signed-in history and favourites are stored on the Tiger server. A sentence in a language you have not downloaded is sent to a model provider to be translated; a downloaded language is translated on the phone. The privacy policy says exactly what goes where.
Which languages are there?
English ↔ Thai and English ↔ Chinese (Simplified), both directions. Korean, Japanese and Vietnamese come next; tell me which one you want first and it moves up the list.
Why is a word grey with no label?
That word came back without a part of speech, usually because the breakdown stage was unavailable when you asked. Translating the sentence again normally fixes it.
How do I delete my history?
Delete a row from History. Delete your account to remove all of that account's server history; deleting the app only removes its local cache.
What does it cost?
Nothing. An account is optional; there are no ads, subscriptions or in-app purchases.
