If you delete a lesson does it delete all the new words and LingQs you gained?

I don’t like having too many lessons in my imported lesson lists but I don’t want to lose my progress if I delete them all.

No, no impact on your LingQs or known words.
Happy deleting!

I delete always everything if I don’t use it anymore. I like to keep my libraries clean. You won’t have any problem.
