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.
All of these calls happen only at the moment the user actively looks up a word, and each can be turned off in the extension's Options page. All are free public APIs; no account, API key or payment is involved.
• The selected word, and the example sentence taken from the page → api.mymemory.translated.net, to get a suggested translation into Vietnamese or English. For single words the lookup goes Korean → English → Vietnamese, so the intermediate English word is also sent to the same service.
• The selected word → translate.google.com, to get a public text-to-speech pronunciation clip.
• The selected word → ko.wikipedia.org, to find illustration images for it and, when the user saved the word on its own, to find an example sentence.
• The article title matching that word → en.wikipedia.org, and a search term derived from it → commons.wikimedia.org, to find further openly licensed illustration images.
• No user text is sent to upload.wikimedia.org; it is contacted only to download the image files the user chose.
No other domains are contacted.
Flashcards (word, meaning, example sentence, pronunciation audio and any illustration images) are saved directly into the user's own Anki desktop app via the local AnkiConnect add-on. Audio and image files are downloaded and written into the user's own Anki media folder. All of this stays entirely on the user's machine.
Extension settings are stored via the browser's chrome.storage on the user's own machine: default deck name, AnkiConnect address, selected Anki note type and its field mapping, interface language, meaning language, image count and image source preferences, the on/off switches for auto-translate, auto-audio and auto-image, and — for the optional study panel — an exam date and optional exam name entered by the user, plus the study timer lengths.
The optional study panel also keeps, on the user's machine only, the state of the study timer and the most recent count of notes in the user's chosen Anki deck. That count is read from the user's local Anki collection through AnkiConnect and is never sent anywhere.
When a word is saved from Chrome's built-in PDF viewer via the right-click menu, the selected word is briefly held in the browser's session storage so the extension's panel can pick it up, and is removed as soon as it is read.
None of this data leaves the user's machine.
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.
