✨ Key Features

🔵 Overlay Translation

Translate text from any app while using it — games, webtoons,

documents, news, and more. No need to leave the app you're using.

🔒 Privacy Protection

━━━━━━━━━━━━━━━━━━━━━━

📵 No Internet Transmission

Captured images and recognized text are never sent to any

external server. Translation results also stay on your device.

📱 Fully On-Device Processing

All text recognition (OCR) and translation are processed

locally on your device via Google ML Kit,

with no internet connection required.

🗑️ Instant Deletion

Captured images are never saved. They are immediately

deleted from memory after translation is complete.

📷 Capture Method

The "Start recording" prompt is an Android system requirement

to grant screen reading permission.

No data is continuously recorded or transmitted.

A single still frame is captured only when the user

releases the floating button, and is immediately

deleted after translation is complete.
