Privacy Policy - Sublens

Sublens ("the extension") is a Chrome extension that blurs subtitles on Netflix, YouTube and Prime Video and lets you translate, define and hear the words in them. This policy explains exactly what the extension does and does not do with your data.

Data we collect

None. Sublens does not collect, store, transmit or sell any personal information. There is no analytics, no tracking, no advertising, and no account or sign-in.

What is sent to third parties

To translate and pronounce words, the extension sends data to Google Translate only when you actively trigger a lookup:

The word or phrase you click or select in a subtitle is sent to Google Translate to return its translation and dictionary entry.
That same text is sent to Google Translate's text-to-speech endpoint to return the pronunciation audio.

Only the text you choose to look up is sent. No full subtitles, browsing history, or identifying information is transmitted. These requests are handled by Google under Google's Privacy Policy.

Settings storage

Your preferences (such as the chosen languages and the on/off toggles) are stored using Chrome's built-in storage API. If you are signed in to Chrome, this may sync across your own devices through your Google account. These settings never leave Google's storage and are not shared with us or anyone else.

Permissions

storage - to save your settings.
scripting and host access to netflix.com and youtube.com - to read the on-screen subtitles and control the player so the extension can work.
host access to translate.googleapis.com and translate.google.com - to fetch translations and pronunciation audio.

Children's privacy

Sublens is a general-audience tool and does not knowingly collect any data from anyone, including children.
