The extension works in Chrome on a computer; the dictionary works in Telegram too.

Privacy Policy

How the WordSub extension for Google Chrome, the website wordsub.cc and the Telegram bot @wordsub_bot handle your data.

Effective October 30, 2026

Everything works on your device

WordSub translates subtitles right on your device with Chrome's built-in translator. Your dictionary and settings are stored in your browser. Nothing leaves your device unless you link a Telegram account. Removing the extension deletes everything it stored in the browser.

What reaches the WordSub server

The WordSub server (webapp.wordsub.cc) receives data only in the cases below, all of which need a linked account:

  • Sync, once you link Telegram (optional): the words in your dictionary with their translations, an example sentence where you met each word and the page address (site and path: the query string and the fragment are removed), your test answers and watch time.
  • Translation into a language Chrome cannot translate on your device: only the word or subtitle line goes to the server, which has Google Translate and MyMemory translate it; they receive only the text. Text sent for translation never comes with the address of the page.
  • AI subtitle translation (PRO), if you turn it on: the subtitle text of the video, without the page address.

“Subtitles from audio” sends the tab's sound to Chrome's speech recognition, a Google service. The WordSub server never receives the audio.

Your Telegram account data (your name) is used only to sign you in. We do not store your numeric Telegram ID.

What we never do

No ads and no tracking. We do not sell your data or share it with anyone.

The use of information received from the WordSub Chrome extension adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.

Deleting your data

Write to @wordsub_bot and we will delete your account and all of its data within 30 days.
