Quick Anki uses names of user's Anki decks to let them choose which decks to add a new card to. At the moment no personal data is sent anywhere. In the future, we may collect clicks for statistics in which case the privacy policy will be updated.
Quick Anki uses Chrome (Chromium) and browser's Web Storage API (localStorage) for storing user's chosen decks so that they don't have to choose it every time they reload a page.
At the moment, this website doesn't collect or send any personal data but may do so in the future in which case the privacy policy will be updated.
