The extension does not collect, track, or centrally store any personal data — it has no backend server. It does not collect browsing history, does not use cookies, and does not use any analytics or tracking tools.
When a user highlights a Korean word, exactly two things are sent out:
The selected word and its example sentence → api.mymemory.translated.net, to get a free suggested Vietnamese translation.
The selected word → translate.google.com, to get a free text-to-speech pronunciation clip.
Both are free public APIs, no account or key required. These calls only happen when the user actively selects a word, and can be turned off entirely in the extension's Options page.
Flashcards (word, meaning, example, audio) are saved directly into the user's own Anki desktop app via AnkiConnect at 127.0.0.1:8765 — this stays entirely on the user's machine.
Extension settings (deck name, note type, field mapping) are stored via the browser's chrome.storage.sync, tied to the user's own Chrome account, same as any other Chrome extension using that API.
The extension requests access to run on all websites (<all_urls>) because its core feature — highlighting Korean text — needs to work on any page the user is reading, not a fixed list of sites. This access is only used to detect a Korean text selection and show the save button; no other page content is read, sent, or stored.
Questions about this policy can be sent via the developer contact listed on this extension's Chrome Web Store listing.
