Remove from Deck (and when to use it)

We’ve tried hard to make sure your time spent learning is used as efficiently as possible. For that reason we provide a Remove from Deck button for each item which will make that word disappear into a black hole and never be seen by you again. If you do this to a kanji, it will count it as learned and unlock any associated vocabulary. These are the times when you'll want to use that button:

Those are the main two reasons you’ll want to use that button. A good rule of thumb is: if you think that if you never saw that word again for the next 3 months that you would still know what it means and how to read it, then you should be safe deleting it. If you accidentally delete a word you want to keep, there’s an undo button that pops up for 5 seconds that will bring it back. Beyond that, if you search for the word using our search bar, you can “learn” it from there, which will add it back to your review queue. So if you destroy one and later regret it you can still bring it back.
