Do I lose my LingQs and known words if I delete an imported lesson?

I imported far too much text for a single lesson - an entire chapter of a book. I really think I should delete it, divide it into smaller chunks, and upload the chunks. But I’ve already read through the lesson, and marked all the blue words either known or LingQs. I would really hate to lose that progress. I can delete a lesson without losing any words, right?

Don’t worry, the lingqs are not related to the lessons. The lessons just display your lingqs in yellow, the same lingqs will be displayed in any new lesson. Feel free to delete your imports.
PS. Please make sure Alex or any other LongQ administrator confirms my understanding. I’d recommend to wait for their confirmation :wink:
