Can I reset my settings?

Hi,
There is no general reset button, but ist should be quite easy to adjust your settings to the values you want directly on the website:

For the training configuration:  That is the modes you want to use to learn (Reading, translation, Writing, ... ) and the frequency you want to learn (Sleeping days and number of repetitions). This can be changed on My Page - Settings . You can then decide if those changes should be applied to all of your existing cards or only for new cards.

As for the cards, the cards you have selected can be deleted. Go to the Content - My flashcards view and you will see the list of cards. If you have many cards you may select the page length to be 100 cards (at the bottom of that page). Then you can delete cards in batches of 100 cards each.

Hope that answers the question!

Thanks a lot!
