DualSubtitle does not collect, store, or transmit any personally identifiable information.
When a YouTube subtitle appears, its text is sent to Google Translate solely to produce a translation. This request is made directly from your browser to Google's servers. We do not receive, log, or store the content of any subtitle.
Your ON/OFF preference is saved using Chrome's built-in storage API and may sync across your signed-in Chrome devices. No other data is stored.
Translation is performed by Google Translate. Please review Google's Privacy Policy for details on how Google handles translation requests.
