Confidentialité

Une confidentialité liée à une première version ciblée.

EnglishCC is a browser extension for YouTube-based English learning. It helps users render clearer English captions, look up words, save vocabulary, and review saved words. The first public version does not require accounts, payments, advertising tracking, analytics, or cloud synchronization.

Last updated: July 5, 2026

Data EnglishCC Handles

  • Website content: caption text from supported YouTube video pages, selected words, related subtitle sentences, video titles, video URLs, and the video timestamp when a word is saved.
  • User activity: lookup history, saved vocabulary, learning status, review progress, and user-selected caption and dictionary settings.

How Data Is Used

  • To render a custom English caption layer on YouTube.
  • To show basic lookup cards, save vocabulary, and remember the original subtitle sentence and source video.
  • To display, sort, group, and review saved vocabulary in the vocabulary book and study page.
  • To play word pronunciation when the user actively clicks a pronunciation button.

Local Storage

  • Caption display settings, dictionary settings, saved vocabulary, lookup history, source video references, and cached meanings are stored in local browser extension storage.
  • The first public version of EnglishCC does not provide an account system and does not sync vocabulary to EnglishCC servers.

Third Parties and Remote Requests

  • EnglishCC does not execute remotely hosted code. Extension pages use JavaScript and CSS bundled with the extension.
  • When the user actively clicks a pronunciation button, EnglishCC may request pronunciation audio for that word from dict.youdao.com. If remote audio is unavailable, it falls back to browser speech synthesis.

What EnglishCC Does Not Do

  • EnglishCC does not sell or rent user data.
  • EnglishCC does not use or transfer user data for purposes unrelated to its single purpose.
  • EnglishCC does not use user data for creditworthiness, lending, advertising profiles, or third-party marketing.

User Control

  • Users can delete locally stored data by clearing the extension storage in their browser.
  • Users can uninstall the extension to stop EnglishCC from processing YouTube pages.
